First, don't make any physical changes to your setup - they aren't necessary.
And you don't need to move /boot either.

As you watch your boot sequence you should see the SCSI drive being initialized.  Look 
at this 
closely and you should see the BIOS drive number. Something like 0x81 or just 81.

Then check out: man lilo.conf
In the section  disk=device-name

Add some lines to lilo.conf near the top like this:

disk=/dev/sda
                bios=0x81

then run lilo and reboot!

I ran into this problem when a BIOS update caused the IDE ZIP drive to be BIOS drive 
82 which 
moved my SCSI drives to 83 and 84.

Linux not only doesn't prevent you from shooting
yourself in the foot, it asks you what caliber
weapon you need to do so.
