failing to boot is NOT the same problem as problems with lilo.conf of lilo

which may explain why you have wierd behavior if you did try those
whacky disk reassignment commands in lilo

you can boot ... anything ... even w/o "/" mounted ... you'd just get
kernel panic or "/" ( aka init ) not found
booting sequence has nothing to do with the rootfs

a super important detail that you will need to do.. to prove that
you can boot from /dev/hda or from /dev/sda
label = hda-vmlinuz
label = SDA-vmlinuz
than see what is booting .. or attempting to boot

usually lilo and grub problems are misconfigured files ...

i do NOT wsee any problems with lilo or grub with ide vs scsi disks
- and you named it... i probaby get whacko trying to boot it

precisely ... no lilo buggss.. affecting "booting"

that does create problems ... depending on what the mbr contains or lacks
