booting to slackware

[metguru]

I have 3 OSs installed on my computer, two of which boot. Slackware is not booting correctly for me at all. I must have something wrong with grub, but I can't find out what it is, so here is the grub entry:

title Slackware, kernel-generic-2.6.21.5
root (hd0,3)
kernel /boot/vmlinuz-generic-2.6.21.5 root=/dev/hda4 resume=/dev/hda3 ro
initrd /boot/initrd.gz
quiet
savedefault

[edit] when i try to boot, it gives me an error: 15, file not found. I checked but the files exist. I'm not so sure about the initrd line, which may be the problem, so I tried removing it, and it started to boot for like 5 seconds, but then gave me an error.

In which partition did you install Slackware? Is it /dev/hda4? Does vmlinuz-generic-2.6.21.5 file exist in the /boot folder of hda4 partition?

Boot up any other OS and Execute fdisk -l command. Post output here.

I think the initrd it's the file how's not found .

i guess it's Slackware 12 so you are using the generic kernel and there is a line indicate the initial ram device ,so have you done the initrd for your machine ?

I don't think I have done initrd, as I don't really know what it is. I was just trying to fill in the blanks from another entry that I copied.

This will not work , have a look in your /boot under slackware partition ,Slackware uses the huge kernel wish you can boot it without the initrd , so and correct the lines to pint to your Slackware kernel and remove the line concerning the initrd.

In my grub menu list this is the entry for Slackware 12.
Slackware on hdb6
title Slackware
kernel (hd1,5)/boot/vmlinuz-huge-smp-2.6.21.5-smp root=/dev/hdb6 ro vga=791

kernel (hd1,5)/boot/vmlinuz-huge-smp-2.6.21.5-smp root=/dev/hdb6 ro vga=791

post the output of fdisk -l , make sure that the name of the Slackware kernel is as you mentioned above . try to put like this

root (hd1,5)
kernel /boot/vmlinuz-huge-smp-2.6.21.5-smp root=/dev/hdb6 ro vga=791

I did this, and got an error:
VFS: cannot open root device hda4 or unknown-block (0,0)
Please append a correct "root=" boot option
kernel panic - not syncing: VFS: unable to mount root fs on unknown - block(0,0)

So this is not your Slackware root partition so please post the output of fdisk -l .

Post the contents of /etc/fstab and /boot/grub/device.map files too.
