19 Chapter 2

Unlike floppy drives, IDE hard drives can connect in either position on

the cable. If you install two drives to a single connector, you will need to

set one as the master and the other as the slave. You do this by setting the

jumpers on the drives. If you use just one drive on the connector, you

should set the drive as the master. See the documentation that came with

your drive for more information.

Connect the first hard drive to the other end of the cable. Wire 1 on the

cable should also connect to pin 1 on the hard drive connector, which is

labeled on the drive circuit board. Check the documentation that came

with the drive for more information.

2.3 Floppy Drive Connector (FDD1)

You can attach up to two floppy disk drives to the AIMB-556's onboard

controller. You can use 3.5" (720 KB, 1.44 MB) drives.

The motherboard comes with a 34-pin daisy-chain drive connector cable.

On one end of the cable is a 34-pin flat-cable connector. On the other end

are two sets of 34-pin flat-cable connector (usually used for 3.5" drives).

The set on the end (after the twist in the cable) connects to the A: floppy

drive. The set in the middle connects to the B: floppy drive.
