opensuse 10.3 grub - 2 kernels


I just upgraded an old PC from openssue 10.2 to 10.3, works fine.

10.3 runs I then wanted to add the old 10.2
kernel, and at boot, choose which kernel i needed. Granted - booting the
older kernel - some things will not work.

point is one application that cannot run with the newer kernel.

/boot/grub/menu.lst works fine for the new kernel:

  • the linux root filesystem is /dev/sda6 - yes, i know - a mess.

So I installed and compiled the older kernel from source, installed,
etc…and then copied and modified this entry for the 2nd older kernel
to be able to boot from GRUB.

however; it seems grub does not see this kernel properly at /dev/sda,
but appears to recognize the hard disk at /dev/hda. the boot then fails
saying (paraphrase)

waiting for device /dev/sda6 to appear.
then later:

(some USB messages…etc…etc…)
want me to fall back to sda6 ?

it seems the old kernel is somehow confusing /dev/sda6 with some USB
drive it expects ?

Any tips on how i can fix this and get these 2 kernels to live together ?

Thanks in advance

Shawn, I’m no expert, but perhaps the 10.2 problem lies in this (the hd0 part)?

(fd0) /dev/fd0
(hd0) /dev/sda
(hd1) /dev/sdb

Nothing comes to mind about how to deal with the 10.2 hda map need, since 10.3 needs sda mapped. perhaps by posting this, the thread will pop to the top and some guru will bless us with his/her wisdom.

But won’t you also have a problem in fstab too? Would going to this format help?

replaces /dev/hda6 (or whatever) in both menu.lst and fstab?
