grub-0.97 reboot

[pulkit]

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
