yeah.. dell bios wont allow you to change between hd0 and hd1 etc
but most bios do have boot order someplace

my boo-boo ... was thinking usb-stick instead of sata
scsi vs hd0(hda) in your case

boot=/dev/hda as you already noted
the machine ( bios ) will look at the boot order..
and find the first machine listed and see if it has the
MBR with the boot flag and will keep looking thru
all the disks till the bios finds a bootable(usable) MBR

either waill work
mv /boot/map /boot/map.hda
will preserve the working mbr, if you want to undo
your changes back to what it was

than run lilo with boot=/dev/sda ...
and put scsi before hda .. and if you cannot change the boot order,
than, as oyu noted in your lilo.conf, run lilo on both disks

that's because it found the old MBR before the scsi
you can also delete the MBR infor from /dev/hda and it will never
boot from /dev/hda
dd if=/dev/zero of=/dev/hda bs=446 count=1 data=sync
or
lilo -U ( and lilo.conf will need to have boot=/dev/hda )
or
fdisk /mbr
