Micropolis 1518 Jumper Settings

There's a pretty slick controller for ISA by Lark Associates which is
capable of lying to the PC in a way which actually convinces it you have two
physical drives. This makes using such large beasts much easier. I've not
been able to get good mileage out of my Miniscribe 9760 or my Maxtor 8760
since it ( the controller ) gave up the ghost. My WD controllers won't help
with making it old-bios-compatible.
