[svlug] Booting SCSI - no MBR

I had an old Quantum 2G drive that finally died on me, so I replaced it
with a new 9G ultra fast and wide Quantum. My motherboard (an I-Will) has
the adaptec 7880 chipset onboard. This is the only hard drive in the
system. The Adaptec Bios reports this drive as C:
BIOS is setup to boot A, then C, then SCSI.
I installed Slackware 3.5 from floppy & IDE CD-Rom, fdisking the drive
with Linux's fdisk command, and setting the first partition (which is 1G)
as bootable. This first partition is within the 1024 cylinder limit (the
drive reports something like 1196 cyliders for the entire drive.)
I tried to install LILO to the MBR, but since there was no MBR yet, I
setup LILO on the first partition.
Normally, I make the drive work with DOS first, which installs a MBR, but
I wanted to do a complete setup using only Linux (plus I would have to dig
though many old dustly boxes to find anything resembling DOS :-)
During Boot, the system hangs right after it checks for a bootable floppy.
So.. I boot off floppy and then mount sda1 as root and the system is
happy.
My best guess is that it won't boot without an MBR. How do I go about
installing one with Linux? I checked through LILO and SCSI How-To's and
didn't find anything...
