Hi Dhruva,

With Lilo, you could add another boot entry that has everything the same
except it points to /dev/hde such as:

image=/boot/bzImage-2.4.18
        label=hde-example
        read-only
        root=/dev/hde7
        append="hdc=ide-scsi hda=none hdb=none hdd=none"


But Lilo is a pain.  Any chance you could you switch to grub?

I have a system thats booting off of /dev/hde3 with grub (using the
additional on-board Promise ATA-100 controller, not the main ATA-66
controller for /dev/hd[a-d]) and it works quite nicely.  As a bonus,
grub also allows you to edit the boot options *AT BOOT TIME* which is a
huge help if you suddenly find that you made a mistake in the
configuration.

Heres a grub.conf example:

default=1
timeout=10
splashimage=(hd0,0)/grub/splash.xpm.gz
title Custom Kernel
        root (hd0,0)
        kernel /bzImage-2.4.18 ro root=/dev/hde3 hdc=ide-scsi vga=1
        initrd /initrd-2.4.18.img


hth,
Ed
