[comp.os.minix] SCSI/floppy booting

jscharles@cup.portal.com (John M Scharles) (06/09/90)

The Seagate 8 bit scsi interface has no ROM routines
to handle floppy drives. The problem you're experiencing
is due to the AMI bios looking for a signature byte 0x55AA
at the end of the boot sector. Unfortunatly Minix stores
some info in these last few bytes! You'll have to recompile
the files that make up the image on the boot disk moving all
the minix info up a few bytes, and add 55AA at the end of the 
sector. Remember to update all references to reflect to new
addresses!

By the way, the Seagate SCSI interfaces shouldn't present
any great problem to writing a device driver for minix. I'm
writing drivers for some other systems so maybe I can come up
with one for Minix
