skoric at eunet dot rsMore detailed information about LILO (Linux Loader) itself you may find in wonderfull LILO mini-HOWTO.
Bill Wohler wrote in his v1.1 of The Linux+WindowsNT mini-HOWTO:
"Due to hardware or software problems or user headroom, I pulled my hair out for several days trying to get both NT and Linux happily settled on my new HP Vectra PC at work."
I could say that was true in my case too, but you really have a way to make both Linux and Windows NT co-existing on the same machine and to switch from one of them to another.
"Under no circumstances run the Disk Administrator from NT 3.51 to format partitions. It asks if it can write a signature "which will cause absolutely no harm." When it did this, it hosed my partition table until fixed by steps 3 and 7 below. Because of these problems, I was limited to one FAT NT partition. Also remember that even if you do get the Disk Administrator to work, you'll want at least one small FAT partition to use as a staging area for exchanging files between Linux and NT until Linux has an NTFS filesystem."
Well, NT's Disk Administrator is sufficient tool to check what situation on your hard disk(s) you have, before and after you used an utility called Partition Magic by Power Quest. This utility might be needed to 'shrink' your NT (either NTFS or FAT) partition, in order to get some free space for your further Linux' partitions. (After a while, I recognized that 'shrinking' used partition might not be needed. Actually, if you start from 'scratch', it might be the best way to re-format your whole disk(s) using FDISK command. You should make a DOS boot floppy diskette where DOS commands FDISK and FORMAT have to be also copied. More details later...)
"I installed Linux first and then NT, but based on my experience, I might now be able to install NT first and then Linux."
Of course you all are able to install Windows NT first and after that Linux. We'll see how to do that and how to use LILO (Linux Loader) to chose which operating system to boot. But, before that we'll see the procedure that Bill Wohler, the previous maintainer of this mini-HOWTO, has been using:
1. Install a minimal Linux (hold off on installing the rest until you win the Linux/NT battle). Do all your disk partitioning in Linux, including your NT partition (make it FAT). I was not successful at making more than one NT partition. I also made it the first partition, but I don't know if that is essential or not.
2. Edit /etc/lilo.conf and use boot=/dev/sda (I
was not successful
at installing LILO on the Linux partition--/dev/sda3 in my case) and
run "lilo". You'll have to use the editor ae. You'll live.
3. Save the MBR with this: dd if=/dev/sda of=/dev/fd0 bs=512 count=1 Use a floppy. Trust me. Also do this each time you change the disk partition table.
4. Install NT, part 1. When it goes to reboot halfway through the process you'll boot into Linux.
5. Add NT stanza to /etc/lilo.conf, e.g.:
other=/dev/sda1
label=NT
table=/dev/sda
and run lilo. If lilo complains about this (I forget the message), add the "linear" flag to /etc/lilo.conf near the "compact" keyword. Furthermore, if your partition table is screwed up by NT you'll either need to use "ignore-table" or follow the directions in Step 7. See also "fix-table". The LILO HOWTO is your friend.
6. Reboot, select NT from LILO, and finish NT install. You'll need the "Boot Disk XU, HP Vectra AIC 7880 Driver A.01.02" floppy to install the ethernet drivers and the "XU/VT Drivers and Documentation" CD (directory video/disk4 if I recall correctly) to install the video drivers for the Matrox MGA Millennium.
7. Back to Linux, run fdisk and ensure you don't get "partition doesn't end on cylinder boundary" on your Linux partitions. You'll still have this error on the NT partition though, but this seems to be OK.
/dev/sda1 1 1 322 329301 6 DOS 16-bit >=32M
Partition 1 does not end on cylinder boundary:
phys=(321, 39, 9) should be (321, 63, 32)
Cfdisk reports strangeness, but it seems OK:
Unusable 0.04*
/dev/sda1 Primary DOS 16-bit >=32Mb 321.59*
Unusable 0.39*
If you do get the cylinder boundary warning on your Linux partitions, it is sufficient to use cfdisk to do something innocuous like changing the boot sector.
If, however, NT has really screwed you over and cfdisk can't even run, complaining that it cannot open /dev/sda, then you'll need to take more extreme action. You'll need that MBR you saved previously. Clear and restore the MBR (but not the signature) with:
dd if=/dev/zero of=/dev/sda bs=512 count=1
dd if=/dev/fd0 of=/dev/sda bs=510 count=1
8. Install the rest of Linux. Easy, huh?
If you prefer to have NT write the MBR instead of LILO, you may have to resort to the following to clear the MBR first:
Epilogue: After first posting this message, I heard from several folks that they had no problems with NT's Disk Administrator, and were able to install either NT or Linux first without any problems. Hopefully, you'll be in this camp, but if not, perhaps this campfire story will be of some use.
Since the first edition of this mini-HOWTO, others have written similar documents as well. Please be sure to consult them. If your experience differs from any presented, then you should submit your own mini-HOWTO or submit a revised version of this document to the HOWTO maintainer (reference this sentence) and send a carbon copy to me as I don't have the time to maintain this document. Someone should eventually combine all of these documents into a single coherent HOWTO.
Finally, I'm afraid this document details all I know about this subject. I should point you to an appropriate Linux newsgroup for further information. I use NT about one day a year. Under duress.
/etc/lilo.conf file. After you make those changes,
restart Lilo with a command: /sbin/lilo and, after the next
re-boot, you will have both 'linux' and 'nt' (or 'dos' or similar)
entries under Lilo menu.
other=/dev/hda1
label=nt
So, the whole /etc/lilo.conf looks like this:
boot=/dev/hda
timeout=50
prompt
default=linux
vga=normal
read-only
image=/boot/vmlinuz-2.2.12-20
label=linux
root=/dev/hda3

label=nt
/etc/lilo.conf
file: After I have installed Windows NT, I assigned the letter C:
to that drive. Beside that, I wanted to have another NTFS
partition in order to store and backup important files, case I
have to re-install NT on C: for some reason in the future. That's why
I've made another NT partition, that has been assigned as D: disk.
Both NTFS partitions are approximatelly 3 GB each and Linux setup
found them as /dev/hda1 and /dev/hda2 partitions. The rest free space
on the disk was cca. 2 GB, where I have made the /root partition of
near 1.9 GB and /swap part of cca. 100 MB (/dev/hda3 and /dev/hda4
respectively). Lilo went to the MBR and all has been running fine.
For your information, I wanted to make these linux partitions that time. Later, I found that it was not needed, so now I let Linux setup to make partitions from the free space in a way it likes to do that. I trust it :-)
Notice: Folks, you see, at my place, one of computers has several SCSI disks. That's why I put the word 'SCSI' in parentheses. There I have a couple of SCSI controllers, a SCSI CD ROM drive and a SCSI Tape drive. That doesn't mean that *you* will be using SCSI parts at all. You'd rather handle more than one IDE disks, but I hope that install process shouldn't change too much, if any.
/etc/lilo.conf file. When you open this file for the first time,
you'll see that there is only one (or more) Linux entry. Well,
you should know the exact position (read: a partition) where
Windows NT has been installed, so you could add an appropriate
entry into /etc/lilo.conf file. After you do that, restart Lilo
and, after the next re-boot, you will have both 'linux' and 'nt'
entries under Lilo menu.
other=/dev/sda1
label=nt
So, the whole /etc/lilo.conf looks like this:
boot=/dev/sda
map=/boot/map
install=/boot/boot.b

/etc/lilo.conf
file: After I have installed Windows NT on the first disk,
I assigned the letter C: to that drive. After I made enough free
space after the NTFS partition, I let Linux setup to
handle further partitioning. Although Linux should support as far
as four primary partitions per disk, it seems that Linux setup is
likely to make an extended partition, whenever it recognizes that
there is already a primary partition on the disk. Considering that
those 'virtual' primary partitions would be numbered from /dev/sda1
to /dev/sda4 (including an extended one, of course), the extended
one should become /dev/sda4. Following that idea, the first one logical
partition within the extended one was numbered as /dev/sda5 (in my
case, it was the /boot partition that physically was the first from
the beginning of the first hard disk). So, the /root and /swap
partitions are /dev/sda6 and /dev/sda7 respectively. You may see a line
"root=/dev/sda6" telling you that. Once again, Lilo went to the MBR
and all has been running fine.
Well, actually, it isn't a real "upgrade" of running NT to 2000, but a "fresh" installation of Windows 2000 Professional. I hope it should also work for other Windows 2000 products. I haven't tried its server-type installations yet, but I remember I haven't experienced any problem with NT, regarding it was Server or Workstation.
/etc/lilo.conf to check it once again. You should have
there at least two options: Linux and NT. Case you don't see the
option to boot your beloved Windoze, you have to add it. It
was described in previous sections. Then you have to run
/sbin/lilo in order to put LILO boot loader into the MBR.
Notice: When I say 'beside Linux and Windows 98', I mean of Linux and Windows 98 that already work together, so they were installed earlier, before we made a decision to add Windows 2000. One of the machines I use at work, has both Linux and Win98. They both load from under LILO menu.
Actually, it is not a very big problem to install Windows 2000 on a computer where another Windows is running. In my case, it is Windows 98 so I just put 2000's CD into the drive. After it recognized that an 'older' version of Windows was running on my machine, it offered me either to upgrade it to 2000 or to install W2k as the 'clean' installation. At first, I tried to upgrade my Windows 98 to W2k, in order to get a very similar combination that I have at home (described in previous chapter). But, some hardware and software compatibility issues were reported (I mean, some of my components wouldn't stay fully operational if I just did an upgrade).
When saw that, I considered to try the 'fresh' installation of W2k, beside Win98 and Linux. Happily, I recently installed another HD into the box, so I did not need to handle the first disk, where Win98 and Linux were living. Actually, the main reason to add the second disk was that the first one got almost full. If I wanted to install the third operating system on the first disk, I'd have to clean it well. So, when W2k's Setup asked for the location to be installed, I told it to use the second disk, repartition it and format it as the NTFS file system (just to mention that my Win98 was FAT32 and Linux was ext2).
After an hour or so, W2k's installation was finished. During the setup procedure, it re-started the system a couple of times. When it was about to do that for the first time, I was curious if it would re-write the MBR, where LILO resides (actually, in the previous chapter, I have mentioned that W2k's installation was likely to re-write the MBR). Interestingly, it did not do that this time, so I continued to see 'LILO boot:' on the screen. But, a *new* thing has appeared after LILO: the Windows 2000 boot loader, that in turn offered not only to load W2k but a 'Windows' (ie. my old Win98) too.
Well, depending on which operating system I like to start, the procedure might slightly differ, but it is easy. No problem at all. For example:
/etc/lilo.conf;
Notice: Recently my bosses decided to get a couple of HP Omnibook 6000 portables, so I quickly rushed to play with new toys. It was a series with Pentium 3 at 1 GHz and 128 MB of RAM. There's also a hard disk of 30 GB, removable DVD and FDD drives, a secondary battery that goes to the removable drive bay (when it's empty) and NIC/modem combo card.
Well, you may ask me why somebody should make a free space somewhere in between. The answer is: In order to allow Linux's /boot partition to stay under well known 1024 cylinder limitation. When it comes to 1024 cyl area (actually, when you enter 1025, 1026 ... etc), it doesn't matter what is happening there. It means, there you may put your Linux / (root) partition (regardless of its size and structure), as well as to use remaining space for Windows/Linux exchange zone (i.e. FAT).
Escape should be pressed one or two times, in order to
change the "boot" device order (of course, a CD/DVD should be
chosen here).
Notice: Well, all I have said in the previous section, resulted in a "multiboot" (or, better to say, "3-boot") system. When I want to run Linux - I have to choose its option from within LILO menu. When I am about to run any kind of Windoze - I have to choose Windows (or DOS, or whatever else) from within LILO menu. Soon after, on the screen appears Windows 2000 boot loader. Finally, from this point, either NT or 2000 may be booted. Well, for a next task, I wanted to install Symantec's Norton System Works onto both Microsoft environments. I did it successfully, but it seems that I have later entered a command that resulted in changing something very important in the setup. In sum, I have become not able to run both flavors of Windows properly. Looks that it was the right time to re-install all the stuff again :-)

| 2 | 7.30 GB | FAT32 | HPNOTEBOOK C: | Primary | |
| 3 | 52 MB | - | - | Primary | |

| 6 | 258,4 | swap | - | Logical | |
| 7 | 2.008,1 | free space | - | Logical |
Next, you may see that I have "shrinked" W2k's FAT32 partition to a smaller size (cca. 7.5 gig), in order to release enough free space for Linux.
I would suggest you to let Linux setup procedure to transform the free space into Linux partitions. I mean, there's no need to prepare the Linux partitions manually. As you can see from the tables, it took cca. 50 megs for the boot part, cca. twice a physical RAM (2 x 128 = 256 megs) for swap and the rest goes for other Linux parts. Remaining free space was probably left after the conversions of various file format systems.

Notice: Folks, that part of the article is NOT a commercial for HP production of any means! In fact, a series of their machines I use has lots of failures in the power supply units, as well as with their hard disks. On the other side, laptop's batteries get exhausted earlier than expected. Other than these issues, HP machines are fine.
HP Omnibook 6000
A laptop computer Omnibook 6000 is equipped with a bootable DVD drive. On the other hand I have supplied a bootable DVD-ROM with Mandrake Linux 9.1 installation. After booting the laptop with that bootable DVD, it gets directly to the installation menu, asking the user to choose a language to use for the rest of the installation.
HP Vectra VL420 (used as a server)
In opposite, an HP Vectra VL420 doesn't have a DVD drive (it only has a CD drive), so the direct installation from that particular installation DVD is not possible. But, an option of making a bootable floppy disk for starting the installation procedure is possible. In fact, several boot images are available for those users who don't have (bootable or not) DVD drive. One of the images is a 'network' one. That means, in a local area network there has to be either a NFS, FTP or HTTP server from which the installation will take place.
HP Vectra VL420 (used as a workstation)
Another VL420 desktop system I also use, has a spare HDD from a previous Windows 2000 server installation (actually, that IDE disk was moved from the other computer where it was a primary one and here it is the second one disk for backup data). The nice things is that it has a HTTP and FTP servers installed (of course, usable if the system is boot from that disk). That was good so I could use one of these servers now. On the other hand, that particular Vectra VL420 was used to install a workstation kind of Linux (that time, using its first hard disk - having Windows 2000 Professional).
System boot of the laptop
As explained earlier, the laptop has a bootable DVD drive, so that's it.
System boot of desktop machines
So, I made a 'network' bootable floppy and booted the first Vectra VL420 (intended to be a Linux server) with it. After a while, it came to a point to choose the installation method (NFS or FTP or HTTP server). At first, I wanted to use the second 'spare' HTTP server on the other Vectra, but regardless of what permission I tried to give to the 'Everyone' group of Windows users, I always got the following answer from the Linux setup:
Error: Couldn't get file ... (or something like that)
Then I tried to use the 'spare' FTP server from the second Vectra and, at first, it also asked for local and remote IP addresses. That time successfully, it started to load a part of the remote Linux files into its memory without any complaint. Soon after, it came to the very same position as Omnibook 6000 did: it got directly to the installation menu, asking a user to choose a language for the installation use.
>From that point, the setup process was almost the same...
I have chosen/confirmed the following items:
- a language to use, besides English(American) as default: I added Unicode and Serbian (both Cyrillic and Latin); - a mouse and keyboard; - a security level - I accepted defaults: 'Standard' for laptop and 'Higher' for server;
The next important task was to choose one of DrakX partitioning options:
- for laptop I chose the 'Use the free space on the Windows partition', because the laptop has one IDE hard disk and I wanted it to use a part of it for Linux (besides existing Windows 2000 Prof. already installed). Windows' Disk Management reported:
Disk 0 15 MB FAT (HP Diagnostics or like)
7.13 GB FAT32 (C: "HPNOTEBOOK")
20.80 GB Free space
The two partitions (FAT & FAT32) were made during the installation procedure, using HP's supplied installation CD's.
At the first moment, Linux setup complained that my Windows partition "was too fragmented" and required me to reboot under Windows, run the "defrag" utility, then restart the Mandrake Linux installation. The defragmentation process have taken cca. 1.5 hour to be completed! When restarted the setup, it wanted to use 7.13 GB Windows partition, instead of 20.80 GB. I chose to 'Use the free space'. Then it made partitions for Linux: /dev/hda5 and /dev/hda7.
- for Vectra VL420 I used 'Custom disk partitioning' because there I had two SCSI disks, one of them running Windows 2000 Server already installed, and the other one I wanted to use entirely for a Linux server. BTW, I wasn't sure what the option 'Erase entire disk' would do during its next step (erase a whole disk or a partition?), although it also may be the proper solution too. DrakX recognized the two SCSI disks as sda and sdb and I chose sdb to install Linux. The first step was to 'Clear all' and after that to 'Auto allocate' the space on that second disk. Finally, after a 'Done' it appeared to make /dev/sdb1 and /dev/sdb6 Linux partitions.
Package Group Selection
Per default, the Mandrake 9.1 setup offers the following to be installed:
- Office Workstation - Internet Workstation - KDE Workstation - Gnome Workstation
that is in sum: Total size 1010/5267 (at laptop) and 1066/5265 (at server).
- for laptop I added all that was available, excepting 6 'Server' items (1612/5267),
- for server I added all that was available, including 6 'Server' items (1708/5265).
Then I got an info, related to selecting following servers (?) on laptop:
cups, postfix, rwho, webmin
and on server box:
cups, openssh-server, postfix, proftpd, rwho, webmin, ypserv, bind and nfs-utils.
Although I was confused about the 'servers' to be installed on a laptop, I have accepted those things to be installed, considering them needed for the proper installation of other packages.
The installation started ...
Interestingly, although the installation on the laptop was performed directly from its DVD drive, the package installation process was significantly faster on the server box. I suppose that was due the difference in performances between server's SCSI disk and laptop's IDE disk.
After that step was finished, and after entering a password for root, setup asked to 'Enter a user' (an ordinary user). The difference between laptop and server installation was that the latter offered some additional tasks for the (ordinary) user:
- access to compilation tools (ctools) - access to rpm tools (rpm) - access to X programs (xgrp) - access to network tools (ntools) - access to administrative files (adm) - allow "su" (wheel)
... and that should be the same for other (new added) users.
Then laptop suggested to 'set up computer to automatically log on one user'. I didn't accept such a solution because I wanted each user to enter his/her password every time he/she is about to log on to the system.
On the other hand, server's setup skipped that particular step and asked where to install the bootloader. I have chosen to use 'First sector of drive (MBR)'.
Soon after, a 'Summary' screen appeared, so I could fine tune the installation. I changed the following items:
- timezone: Belgrade (both machines) - Graphical Interface (reported as 'not configured' on the laptop? - I tried with 'Flat Panel 1400 x 1050' because that resolution runs fine under Windows), X server: Rage Mobility, XFree 4.3 and 16 million colors - 24 bits). On laptop, I chose XFree to start when I reboot. On server, it offered 800 x 600 - due to a recognized monitor Samsung SyncMaster 510(M)s (CHA5807*) and card ATI Rage 128 and 16 bit - 65 thousand color. - Sound card: laptop is ESS Technology|ES1983S Maestro-3i|PCI Audio and server is Intel Corporation|ICH2 810 Chipset AC'97 Audio Controller. - Network: with 'Use auto detection'. Results: on laptop it recognized 'LAN connection - ethernet card(s) detected'; on server it recognized nothing. So, on server I chose to configure 'LAN connection'. Drivers are: 3c59x (laptop), eepro100 (server). IP addresses for both laptop and server. Host name: laptop, server, Gateway: - Firewall: disabled (def.) - Botloader: lilo-graphic on /dev/hda (laptop) lilo-graphic on /dev/sda (server) default boot: windows on /dev/hda2 (laptop) windows on /dev/sda1 (server) - Services: 32 activated for 47 registered (laptop) 24 activated for 60 registered (server)
Soon after ...
Congratulations, installation is complete.
(reboot)
Installation results
The next Windows boot made a screen 'System Settings Change': Windows 2000 has finished installing new devices. You must restart your computer before the new settings will take effect. Do you want to restart your computer now? Well, I said <Yes>
Windows' Disk Management has showed new Linux partitions:
- laptop: 5.85 GB Healthy \ Disk 0 495 MB Healthy - all 3 are logical drives within the extended one 27.95 GB 14.46 GB Healthy / - server: 5.85 GB Healthy - primary partition Disk 1 494 MB Healthy \ 17.12 GB 10.79 GB Healthy - these 2 are logical drives within the extended one
It seems that /boot and /swap partitions are very similar in size,
regardless the disk sizes, but / (root, home etc) partitions depend on
disk size. Note that at my 'laptop' box I used the same HD of 27.95 GB for both
Windows and Linux (for Windows 7.13 GB FAT32 of 27.95 GB available, the rest,
cca. 20 GB for Linux).
At the 'server' box I have two HD's of 17.12 GB each, and I used Disk 0 (the 1st one) entirely for Windows 2000 Server, and Disk 1 (the 2nd one) entirely for Linux.
The first Mandrake Linux boot screen:
- laptop: a screen with only a name of a user (no root available!), Reboot and Halt buttons.
- server: a screen with 'Enter Login', 'Enter Password' and 'Session type' (no name of a user appeared).
First Time Wizard: Default KDE (both)
...
What about the Ctrl-Alt-Del action:
- laptop: a screen 'End Session for "username"' What do you want to do next? Login as different user, Turn off computer, Restart computer, OK and Cancel buttons.
- server: a screen 'End Session for "username"', Logout and Cancel buttons.
After choosing Login as different user (at laptop), or Logout (at server), what appeared were the same screens as described in 'The first Mandrake Linux boot screen' section.
Should you want to learn more about LILO (Linux Loader), configured to boot the systems in the examples above, you should refer to the LILO mini-HOWTO.
HP Vectra VL420 (workstation - desktop client)
As mentioned before, HP Vectra VL420 doesn't have a DVD drive (it only has a CD drive), so the installation from that particular DVD installation was not possible. But, an option of making a bootable floppy disk for it was possible. In fact, several boot images are available for those users who don't have (bootable or not) DVD drive. One of the images was a 'network' one. That means, in a local network there should be a NFS, FTP or HTTP server from which the installation will take place. As earlier explained, a Windows 2000 server machine (that I earlier used for Mandrake Linux server installation), has HTTP and FTP servers installed. That was good so I could use one of them now.
So, I used the 'network' bootable floppy and booted Vectra VL420 with it. After a while, it came to a point to choose the installation method (NFS or FTP or HTTP server). At first I wanted to use my HTTP server but regardless of what permission I gave to 'Everyone' I always got the answer from Linux installation program: Error: Couldn't get file ...
Then I tried to use my FTP server (on the same Windows server) and it also asked for IP local and remote addresses. Then it started to load a part of the remote files into its memory. Soon after, it came to the very same position as Omnibook 6000 did: it gets directly to the installation menu, asking for choosing a language to use.
>From that point, the installation procedure was almost the same...
I have chosen/confirmed the following items:
- a language to use - besides English(American) I also added Unicode and Serbian, both Cyrillic and Latin; - a mouse and keyboard; - a security level - default 'Standard';
The next important point was to choose one of DrakX partitioning options:
- At first I used the 'Use the free space on the Windows partition' because it has one IDE hard disk and I wanted it to use a part of it for Linux (besides existing Windows 2000 Prof. already installed).
At the first moment, Linux setup complained that my Windows partition "was too fragmented" and asked me to reboot under Windows, run the "defrag" utility, then restart the Mandrake Linux installation. After defragmentation process was finished, I tried once again the 'Use the free space on the Windows partition' but it wanted just to 'shrink' Windows partition from cca. 30 gig to cca. 28 gig. Then I used Partition Magic software and tried to shrink it to cca. 20 GB in order to get more free space for Linux.
Than I tried 'Custom disk partitioning', chose the first IDE disk (hda) of 27GB, chose action 'Resize'. That one option was not good because it just offered Windows partition to get larger instead of smaller than before. Finally I used 'Use the free space' and it automatically made Linux partitions. In fact, on that one Vectra I have two IDE disks, one of them having Windows 2000 Server already installed, and the other one having Windows 2000 Prof. that I wanted to use partly for Linux. After 'Done' it came to making /dev/hda5 and /dev/hda7.
Package Group Selection
Per default, Mandrake installation offers the following:
- Office Workstation - Internet Workstation - KDE Workstation - Gnome Workstation
in sum, Total size 1009/5105 (client).
- for client I added everything else (1638/5105), excepting 6 'Server' items.
Then I got an info, related to selecting following server(s) on client:
cups, postfix, rwho, webmin
I have accepted those things to be installed.
The installation started ...
After that step was finished, and after entering password for root, setup asked to 'Enter a user' (an ordinary user). The difference between client and server installation was that the latter offered some additional tasks for the user:
- access to compilation tools (ctools) - access to rpm tools (rpm) - access to X programs (xgrp) - access to network tools (ntools) - access to administrative files (adm) - allow "su" (wheel)
... and that would be the same for other (new added) users.
Then client suggested to 'set up computer to automatically log on one user'. I didn't accept that because I wanted each user to enter his/her password every time he/she is about to login to the system.
Soon after, a 'Summary' screen appeared, so I could tune the installation. I changed the following items:
- timezone: Belgrade - Graphical Interface: it offered 1280 x 1024 - due to a 'custom' monitor and card NVIDIA GeForce2 DDR (generic) - 24 bit 16 million colors. - Sound card: Intel Corporation|ICH2 810 Chipset AC'97 Audio Controller. - Network: with 'Use auto detection'. Results: recognized nothing. So, I chose to configure 'LAN connection'. Driver is: eepro100. IP address Host name: client, Gateway: - Firewall: disabled (def.) - Botloader: lilo-graphic on /dev/hda default boot: windows on /dev/hda1 - Services: 32 activated for 47 registered (the same as laptop)
Soon after ...
Congratulations, installation is complete.
(reboot)
Installation results (all 3 systems)
- laptop options: windows, linux, failsafe, floppy; - client options: windows, linux, linux-nonfb, failsafe, windows2, floppy - server options: windows, linux, linux-nonfb, linux-secure, failsafe
Notes:
- 'windows2' option at the client box is, in fact, Windows 2000 Server installation located on the second HD.
- Not sure why 'laptop' doesn't have 'linux-nonfb' text boot option, although it looks like it boots to Linux in just like that mode (maybe it is a matter of the laptop's LCD screen capabilities or something like that). On the other hand, client and server differ in floppy and linux-secure options (perhaps as some security measures or like).
- 'linux-secure' option at the server box may be a result of a 'Higher' security level, that I have chosen at the beginning of the installation or, maybe, there are some special server security features.
The next Windows boot made a screen 'System Settings Change': Windows 2000 has finished installing new devices. You must restart your computer before the new settings will take effect. Do you want to restart your computer now? Well, I said Yes.
Windows Disk Management has showed new Linux partitions (comparison of 3 systems):
- laptop: 5.85 GB Healthy \ Disk 0 495 MB Healthy - all 3 are logical drives within the extended one 27.95 GB 14.46 GB Healthy / - client: 5.68 GB Healthy \ Disk 0 494 MB Healthy - all 3 are logical drives within the extended one 37.28 GB 3.52GB Healthy / (same as laptop) - server: 5.85 GB Healthy - primary partition Disk 1 494 MB Healthy \ 17.12 GB 10.79 GB Healthy - these two are logical drives within extended
It seems that /boot and /swap partitions are very similar in size,
regardless the disk sizes, but / (root, home etc) partitions depend on disk
size. Note that at my 'client' box I used the same HD of 37.28 GB for both
Windows and Linux (for Windows 27.60 GB NTFS of 37.28 GB available, the rest,
cca. 10 GB for Linux).
At the 'server' box I have two HD's of 17.12 GB each, and I used Disk 0 (the 1st one) entirely for Windows 2000 Server, and Disk 1 (the 2nd one) entirely for Linux. That's why Mandrake setup allocated 'less' space for / at the larger disk (in fact, at the 'server' box, it allocated relatively much more space for / even that HD is smaller - because that HD is 'dedicated' for Linux only.
The first Mandrake Linux boot screen:
- laptop: a screen with only a name of a user (no root available!), Reboot and Halt buttons.
- client: a screen with only a name of a user (no root available!), Reboot and Halt buttons.
- server: a screen with 'Enter Login', 'Enter Password' and 'Session type' (no name of a user appeared, but root may also login there!).
First Time Wizard: Default KDE (client, just like the others)
There is a difference between KDE screens at client and server: the client VL420 offers 'CD-ROM mounted at /mnt/cdrom' and 'Floppy mounted at /mnt/floppy' but server Vectra VL420 (having the same type of devices!) doesn't. Besides that, if a flash storage is connected to a USB port, before Linux being started, there will also appear an icon for it. Interestingly, at server there's no something like that. I consider, that is also a matter of the difference between the client and server types of Mandrake Linux installations, or maybe a matter of some security measures for server-type installations. Whatever it is, I see that as a shortage of confortable for Mandrake Linux servers. Case some of you, the readers, has some workarounds on that issues, your contributions are welcomed!
Besides that, KDE's Panel at client offers 'Mandrake Control Center - System configuration tool' (although useful only under root privileges), and KDE's Panel at server doesn't have that (in fact, an 'ordinary' user may access the same tool from the Start Applications menu and, again, to use it after the root's password entered). It makes me wonder why they at Mandrake did it like that. Maybe they didn't want 'ordinary' users to access some configuration tools as easily ...
...
What about the Ctrl-Alt-Del:
- laptop: a screen 'End Session for "username"' What do you want to do next? Login as different user, Turn off computer, Restart computer, OK and Cancel buttons.
- client: a screen 'End Session for "username"' What do you want to do next? Login as different user, Turn off computer, Restart computer, OK and Cancel buttons.
- server: a screen 'End Session for "username"', Logout and Cancel buttons.
After choosing Login as different user what appeared were the same screen as described in 'The first Mandrake Linux boot screen' section.
Should you want to learn more about LILO (Linux Loader), configured to boot the systems in the examples above, you should refer to the LILO mini-HOWTO.
There is also a difference between client and server behavior when it is about to shutdown (halt) the system. A user is capable to halt the system even from the login screen at client (that is not available at server). On the other hand, a user has to know root password to halt the system at server.
A 'Network' bootable installation floppy should also be capable to reach Mandrake installation files not only from NFS, FTP or HTTP servers, but files that are copied to shared disks on machines within the local network. When an image is called a 'Network' image, that means, IMHO, all kinds of network locations should be accessible - NOT only those specific server-type locations like NFS, FTP or HTTP servers. In fact, if a user in a local network doesn't have NFS, FTP or HTTP servers, but has the installation packages copied somewhere else on the LAN, there should be a way to access those packages too.
The workstation-like installations do not offer a 'root' account to be used from the graphical login window (I suppose that 'su' or 'sudo' actions are available - I haven't tested them yet). That might be a problem in cases when a user misconfigures his/her account and when the administrator has to login to the system to fix that problem. At the moment, I am not sure how the administrator could do that without having the 'root' login ability (perhaps using virtual text consoles accessed with CTRL-ALT-F1, CTRL-ALT-F2 ... , then starting GUI if needed, etc ...)
Some issues after the Mandrake 9.1 Linux installation:
Talking about the behavior of Mandrake 9.1 - related to the type of installation (a workstation or a workstation/server combination) - it seems that there are some other differences. As already mentioned, on a workstation desktop there are icons for CD and FD drives (although maybe not already being mounted at the moment of the system boot). As well, if a USB flash storage is connected to the USB port, there is also an icon of an sda (SCSI ?) USB storage available. On the other hand, in case of workstation/server installations - there are no icons of those devices at all. It seems that the server installation considers that is better to live without these devices in case of a server :-) Any comments are welcomed.
Related to writing and testing HOWTO's. I prefer to write a 'HOWTO' document
using a text editor and make it with a .sgml extension. Then I use the old,
good sgml2html tool to make HTML pages, in order to check how these
pages will look like. Well, that's OK under Red Hat 7.1 but under Mandrake 9.1 it
seems that I am not able to find the same tool. Any idea on that task?

Recently I had a hard-disk failure and my more_than_a_year old Linux/Windows 2000 home system disappeared. When considering what to have on a new purchased disk, I decided to try Linux with both Windows 2000 and Windows XP.
In short, the new disk was of 40 GB and I made a half of it (20 GB) a NTFS partition for Windows XP. It became so called C: disk. The second partition of 10 GB (FAT32) became D: disk of Windows 2000. As usual, you have to repeat installations of Microsoft products for several times - before they even start behaving partly as you expect from them. To be more precize, it looked that Windows 2000 had to be installed before Windows XP, in order its boot entry got a part of XP's list of boot entries (If I remember, I tried it the opposite way and it didn't work).
Then I used the remaining 10 GB to install Mandrake 9.1 (Bamboo) and I made it without problems - The only minor issue was that a try of disk-type installation where Linux files were placed on an existing NTFS partition failed because Linux setup actually did not manage to locate installation files on a NTFS partition. (That was why I made Windows 2000 installation on a FAT32 file system - because later I could use it for Mandrake 9.1 disk-type setup).
So far - so good. One of the main things I wanted to make working within all three environments was the e-mail client. You bet, an another open source solution was available: the Mozilla suite. For Windows operating systems I used Mozilla 1.7.11 and for Linux I used Mozilla 1.6 (an older xft version - some newer ones I was not able to install). And, as usual for me, I wanted all of them to share my mailbox files, i.e. I wanted to access my incoming emails from all and each operating system - booted at the time.
In order to make that possible, I chose Mozilla under Windows 2000 (FAT32) to become the 'central location' for saving the mailbox files. That means I had to make some changes within other two Mozilla's configurations - to make them capable to read/write from/to the first chosen mailbox location (FAT32). For Linux I did the following:
Instead of keeping an 'original' Linux-native location:
/home/misko/.mozilla/default/fydeba98.slt/Mail/solair.eunet.yuI changed to this mounted one:
/mnt/win_d/Documents and Settings/misko/Application Data/Mozilla/Profiles/default/oeu1tmbd.slt/Mail/solair.eunet.yu
As a result of that change, now it is possible for me to download email messages from within one O.S. - then to read them from another O.S. - and finally reply/send the email from the 3rd one environment. The only minor drawback is that each operating system is likely to 'remember' only its own last known state of Mozilla's Mail & Newsgroups. In order to get a 'refreshed' state of e-mail folders, a user has to click on a mailbox name. Another solution is to activate an option of 'Compact all folders ...'.
What belongs to my 'wish-list' now, is to continue upgrading all three Mozilla's (at least that old one v1.6 that runs under Mandrake). It makes me wonder if I could use a 'regular' one (instead of xft's) - although I remember that older regular's were producing awful fonts under Linux environment. I am not sure if things got improved.
The second important task is to install one of the most popular radio amateur software, also an open-source, called LinFBB (FBB for Linux). More details related to that you can find in another Linux manual: the FBBHOWTO.

Notice: I often participate in various (inter)national ICT conferences in Serbia and abroad, presenting technical papers and delivering half-day and full-day tutorials, covering basic ideas and useful mission of the amateur radio hobby and its possible usage in engineering education. What I have been doing is to spread - as much as possible - the knowledge about existing open source products, including Linux and amateur radio free software. Besides that, I have been writing various articles for a variety of scientific and other magazines. Here you have the list of those articles and paper topics submitted to the conferences.
In case you want to re-publish or forward my volunteer paper works to some journals or other public media around, you are free to contact me. Some of my papers are written in Serbian Cyrillic, some of them are in English and some of them even combined!

Besides the published articles and presented works, I am also a member of the following associations: IEEE Computer Society, IEEE Communications Society, WSEAS and ACM. In addition, I work on establishing an academic computer network that would use the amateur radio stations as the media. Some kinds of proposed networks exist elsewhere on this planet and I invite their administrators to contact me in order to cooperate.

You are strongly recommended to take a backup of your system before major installation and backups at regular intervals.
This is not the first release of this mini-HOWTO. I hope to improve it whenever possible. Besides that, there are other documents that may help you to install more than one operating system on the same computer. You may look for them at the same location where you get Linux+WindowsNT mini-HOWTO.
This mini-HOWTO would be improved from time to time. If you think that the HOWTO on your Linux installation CD is some out-of-date, you may check for newest release on the Internet. It could be found within the main Linux Documentation Project or some of its mirrors.
This version of Linux+WinNT mini-HOWTO is based on:
The Linux+WindowsNT mini-HOWTO
by Bill Wohler, wohler@newt.com
v1.1, 19 February 1997
Credit also goes to:
Dragomir Kalaba, a local Linux 'guru'
Any comments or suggestions can be mailed to my email address: skoric at eunet dot rs
These are intended as the primary starting points to
get the background information as well as show you how to solve
a specific problem.
Some relevant HOWTOs are Bootdisk, Installation, SCSI and UMSDOS.
The main site for these is the
LDP archive
at Metalab (formerly known as Sunsite).
These are the smaller free text relatives to the HOWTOs.
Some relevant mini-HOWTOs are
Backup-With-MSDOS, Diskless, LILO, Large Disk,
Linux+DOS+Win95+OS2, Linux+OS2+DOS, Linux+Win95,
Linux+WindowsNT, Linux+NT-Loader, NFS-Root,
Win95+Win+Linux, ZIP Drive, FBB packet-radio BBS.
You can find these at the same place as the HOWTOs, usually in a sub directory
called mini. Note that these are scheduled to be converted into SGML and
become proper HOWTOs in the near future.
In most distributions of Linux there is a document directory installed, have a look in the /usr/doc directory. where most packages store their main documentation and README files etc. Also you will here find the HOWTO archive ( /usr/doc/HOWTO) of ready formatted HOWTOs and also the mini-HOWTO archive ( /usr/doc/HOWTO/mini) of plain text documents.
Many of the configuration files mentioned earlier can be found in the
/etc
directory. In particular you will want to work with the
/etc/fstab
file that sets up the mounting of partitions
and possibly also
/etc/mdtab
file that is used for the md system to set up RAID.
The kernel source in /usr/src/linux is, of course, the ultimate documentation. In other words, use the source, Luke. It should also be pointed out that the kernel comes not only with source code which is even commented (well, partially at least) but also an informative documentation directory. If you are about to ask any questions about the kernel you should read this first, it will save you and many others a lot of time and possibly embarrassment.
Also have a look in your system log file (
/var/log/messages)
to see what is going on and in particular how the booting went if
too much scrolled off your screen. Using tail -f /var/log/messages
in a separate window or screen will give you a continuous update of what is
going on in your system.
You can also take advantage of the
/proc
file system that is a window into the inner workings of your system.
Use cat rather than more to view the files as they are
reported as being zero length. Reports are that less works well here.
There is a huge number of informative web pages out there and by their very nature they change quickly so don't be too surprised if these links become quickly outdated.
A good starting point is of course the Linux Documentation Project home page, or this one: Linux Documentation Project an information central for documentation, project pages and much, much more.
Please let me know if you have any other leads that can be of interest.
In the end you might find yourself unable to solve your problems and need help from someone else. The most efficient way is either to ask someone local or in your nearest Linux user group, search the web for the nearest one.
Another possibility is to ask on Usenet News in one of the many, many newsgroups available. The problem is that these have such a high volume and noise (called low signal-to-noise ratio) that your question can easily fall through unanswered.
No matter where you ask it is important to ask well or you will not be taken seriously. Saying just my disk does not work is not going to help you and instead the noise level is increased even further and if you are lucky someone will ask you to clarify.
Instead describe your problems in some detail that will enable people to help you. The problem could lie somewhere you did not expect. Therefore you are advised to list up the following information on your system:
Remember that booting text is logged to /var/log/messages which can
answer most of the questions above. Obviously if the drives fail you might not
be able to get the log saved to disk but you can at least scroll back up the
screen using the SHIFT and PAGE UP keys. It may also be useful to
include part of this in your request for help but do not go overboard, keep
it brief as a complete log file dumped to Usenet News is more than a
little annoying.
