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.
Connect the second hard drive to the remaining connector (CN2 or CN1),
in the same way as described above. The secondary IDE shares the same
resource with CF (CompactFlash) socket.
CN61 is used to set CF as master mode or slave mode. While setting CF
as master, the other IDE device connected to secondary IDE can work as
a slave device only and vice versa.
2.3 Floppy Drive connector (CN3)
You can attach up to two floppy disk drives to the AIMB-740-6CB1'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.
