Hi all,

I want to add a small feature to the grub-0.97.
my disk partition layout is
1)partition1-Main kernel(A) and rootfs image(A)
2)partition2-Recovery kernel(B) and rootfs(B).

I have made two entry for these in menu.lst with default set to 0 i.e
always execute the main kernel.
I am checking sha1 of the kernel during boot time and in case of sha1
mismatch i want to boot with the
second recovery kernel and do firmware recovery.

My sha1 is working fine but i am not able to boot with the second kernel
during sha1 mismatch.

Earlier i thought to edit the configuration file(menu.lst) in case of sha1
mismatch and use grub_reboot.
But  no write support is there for ext in grub-0.97.
So I am looking for another methods

Regards
Pulkit

GRUB Legacy isn't developped anymore. Please upgrade to GRUB2.
