If you are using a Macintosh SE with two internal floppy drives and an IOmega
Bernoulli drive, be sure to start up the computer with an 800K System disk in
one of the drives. If you don't, the computer will try to start up from the
Bernoulli drive, and will crash.
In the case of a Macintosh SE with built-in hard disk drive, the computer will
always start up from the built-in hard drive.
