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. CF card is only available for
master mode. While setting CF as master, the other IDE device con-
nected 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-744'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.
2.4 Parallel Port (CN4)
The parallel port is normally used to connect the motherboard to a printer.
The AIMB-744 includes an onboard parallel port, accessed through a 26-
pin flat-cable connector, CN4.
