You couldn't make the disk the startup disk simply because it is a serial
drive and the Mac doesn't look to the serial ports for a bootable drive.  The
reason the HD 20 boots is beacuse it is in the floppy port and the Mac will
boot from something in the floppy port (same thing for the SCSI port).  But
for a serial drive to auto boot, you would have to rewrite the ROMs so that
they would look for a bootable drive connected to them (not done by Apple
because printers and modems usually can't boot).  I have a serial Paradise
and a SCSI Photon 20 (ok, so I'm cheap too, but there is a Rodime 140 in the
mail).  I used to have to boot from a floppy that would run the mounting
program for the Paradise and then Paradise would take over the boot half way
through (this was part of the mounting program).  But I see no reason why
your HD can't be booted from a floppy and then you either launch an application
or the finder on your HD to get it to be the system disk.  This is the closest
you will ever come to auto booting.
