slot has an AHA-274x controller, the address is 0x1C00, and if the adjacent slot

also has an AHA-274x controller, the address is 0x2C00. Motherboard

manufacturers usually map the controller chip on the motherboard at the highest

EISA slot plus 1. Thus in an EISA motherboard with three EISA slots, the

motherboard AIC-7770 address is 0x4C00.

The BIOS base address is selected from a range of choices on the

manufacturer-supplied conﬁguration utility. Common addresses for the AIC-7770

controller are: 0xCC00, 0xD400, 0xD800, and 0xDC00. The controller with the

lowest BIOS base address will become the boot or primary controller.
