Hello,

I run an OS/2 installation on the first partition (primary)
of my second hard disk. After OS/2 installation I had removed
the OS/2 boot manager since I had installed it only for being
able to install OS/2 :-/

Currently I boot OS/2 using LILO (Linux is my primary OS)
which is fine. However since GRUB provides some things I would
like to have, I gave it a try.

My OS/2 section in `/boot/grub/menu.lst' looks like this:

| title OS/2 Warp 4.0
| rootnoverify (hd1,0)
| savedefault
| makeactive
| chainloader +1

This does not work. Neither did anything else I tried (I even
installed LILO with only the OS/2 entry into some partition's
boot record). In the above constellation, GRUB just shows me
the settings and then nothing happens.

The infamous `/boot/chain.os2' does not seem to exist nor is
there any hint how to get it, and the GRUB sources only hint
that booting OS/2 *should* work.

Is there any chance I get this working?

Cheers,

Herbert

I'm pretty sure I made no mistakes here:

| Paulina:~# fdisk -l /dev/hdc
|
| Disk /dev/hdc: 20.4 GB, 20485785600 bytes
| 255 heads, 63 sectors/track, 2490 cylinders
| Units = cylinders of 16065 * 512 = 8225280 bytes
|
| Device Boot Start End Blocks Id System
| /dev/hdc1 * 1 914 7341673+ 7 HPFS/NTFS
| /dev/hdc2 915 1851 7526452+ 5 Extended
| /dev/hdc5 915 1400 3903763+ 7 HPFS/NTFS
| /dev/hdc6 1401 1485 682731 6 FAT16
| /dev/hdc7 1486 1851 2939863+ 7 HPFS/NTFS
| Paulina:~#

Also, if I leave the `noverify' out, GRUB reports me it can't
handle the HPFS file system.

Cheers,

Herbert

okay, let's review:
ide channel 1:
/dev/hda == first device
/dev/hdb == second device
ide channel 2:
/dev/hdc == third device
/dev/hdd == fourth device

/dev/hda1 == first partition on first device, and so on

grub naming convention:
(hd0) == first device, and so on
(hd0,0) == first partition on first drive, and so on.

so, given /dev/hdc1 == 3rd device, 1st part == grub: (hd2,0)
try that and see what happens

I think someone who understands the low level workings of boot sectors
and loaders needs to create one and submit it to the Grub developers. I
don't think anyone ever did. I couldn't find one anywhere.

I tried a long time ago and gave up. ISTR getting a an OS/2 boot from a
primary partition, but not a logical. I load the grub partition with BM.
Works fine.

What is GRUB? And can it be ported to OS/2?

GRUB is a bootloader so it doesn't need to be ported.

I finally fired up my dual-boot machine today and had a look at grub.conf.
It has

title OS/2
root (hd0,1)
makeactive
# chainload OS/2 bootloader from the first sector
chainloader +1

as the relevant OS/2 entry, on my system this results in the OS/2 boot
manager being started which then drops through to OS/2 itself. Obviously
this won't work for everyone, change the (hd0,1) as required for where your
OS/2 boot partition might be.

If you don't know what it is, why do you care where it could or could
not be ported to?

I suspect you know. Admit it.
