Here is what I did to break things...
In an effort to create a boot disk for linux, I followed the instructions as laid out in "Running Linux" (Welsh et al) and ran rdev as root in order to set my root device to hda3 (which it is - I am certain of this).

#rdev /boot/vmlinuz /dev/hda3

I then copied /boot/vmlinuz to the disk and rebooted to see if it would work. It didn't. I got a "Invalid compression format" error.

Oh well, no worries. I rebooted again and GRUB loaded up as usual. Except now I can't mount any floppy disks. (Arg!)

This is the error it gives me

[root@host user]# mount /dev/fd0 /mnt/floppy/
mount: you must specify the filesystem type

Okay. But no matter what file type I specify I always get:

[root@host user]# mount -t vfat /dev/fd0 /mnt/floppy/
mount: wrong fs type, bad option, bad superblock on /dev/fd0,
or too many mounted file systems

So I'm stumped. Any help would be appreciated.

Plus. If anyone can tell me how to make a boot disk (I run RH9), that would be helpful too

Thanks

First - Insert a blank floppy: then

Open a shell and type

su

then type your root password

then type :

mkbootdisk 2.4.20-8

just in case you're interested...

mkbootdisk did in fact make a bootdisk (surprisingly enough), even though I couldn't mount the floppy drive.

The good news is that after booting with the bootdisk (and not GRUB) I could once again mount the floppy drive.

And then, rebooting again using GRUB, I can still mount the floppy drive.

Thanks Skyline
