To whom it may concern:
This question concerns creating an emergency boot disk for Caldera Open
Linux 1.3, which I am using to learn Linux since I have two books of the
"do this, now do that" variety for this distribution.
I would appreciate any reply in language that a newbie can understand.
My configuration: 2 HDs, approx 2MB each, with Caldera 1.3 on hdb
(hda contains Red Hat 6.1)
main OS: Win98, running Partition Magic
The Caldera 1.3 installation CD allows the choice of writing LILO either
to the MBR, a floppy, or the beginning of the Linux root partition.
In an earlier installation, I had put LILO on a floppy (which booted
OK),
but normally booted using Loadlin from DOS 6.22. This time, since I am
happily using Partition Magic, I put LILO in the root partition, but
would
still like if possible to have an emergency boot disk available.
Several sources suggest that the command
dd if=/vmlinuz of=/dev/fd0
would do the trick (my file vmlinuz is in /), but when I try to boot
with
the disk created by this command, either with or without an extra
bs=8192
at the end of the command, and either with or without first running
kfloppy to format the disk
(Extra Question - when is this necessary?),
at the section
>>> kernel: mounting root filesystem <<<
the following messages appear, some recurring several times and with
what
I assume are various memory locations indicated:
attempt to access beyond end of device
unable to read superblock
FAT bread failed
Kernel panic: VFS: Unable to mount root fs on 03:03
Is there an obvious way to fix this, other than twice reinstalling Linux
(first with LILO on floppy, then on the root partition)?
Sincerely,
