About to update RH5.2 kernel, howto update my boot disk?

Post by Jeff Kowalczy » Wed, 17 Feb 1999 04:00:00



Praise be, Redhat released RPM updates for compatibility with the 2.2
kernel... I'm going back for a nother try at getting up to the 2.2.1 kernel,
but I now need to use a boot disk with this old 486/bios. But that's another
story, lets just say I'm going to use a boot disk and live with it for now.

Anyhow, once I manage to get a zimage of the kernel done this afternoon,
what do I have to do to my boot disk to make sure my module symbolic links
and all that jazz are up to date for a multi-kernel lilo boot. I only dimly
had that process down with a bootable hard drive, and I'm a little foggy on
whether an exact analogous procedure exists for boot disks.

Thanks.

I have a new kernel, but I have to use a boot disk at the moment, due to a
bios limitation on this 486. This is RH5.2, and I'm trying to get the boot
disk to load the 2.2.1 kernel I just built.

I have the 2.2.1 image copied over there, and I updated the lilo.conf on the
floppy's /etc dir, how do I run lilo to update on the floppy, not the hard
drive??

In the floppy root, (/mnt/floppy) I have:

vmlinuz-2.0.36-0.7        vmlinuz-2.2.1
/boot
    boot.0200    boot.b    map    message
                (what exactly is the map file?)
/dev
    fd0    hda6
/etc
    lilo.conf

lilo.conf reads:
-----------------------------------------------
boot=/dev/fd0
timeout=100
prompt
image=/vmlinuz-2.2.1
    label=linux
    append="mem=20M"
    root=/dev/hda6
image=/vmlinuz-2.0.36-0.7
    label=linux-old
    append="mem=20M"
    root=/dev/hda6
image=/vmlinuz-2.0.36-0.7
    label=rescue
    append="load_ramdisk=2 prompr_ramdisk=1"
    root=/dev/fd0

However, the only choices at boot time are linux and rescue, which means my
experiments with the various lilo switches have been unsuccssful. Help?
