2.8.1 Connecting the hard drive
Connecting drives is done in a daisy-chain fashion and requires one of
two cables (not included in this packing), depending on the drive size.
1.8" and 2.5" drives need a 1 x 44-pin to 2 x 44-pin flat-cable connector.
3.5" drives use a 1 x 44-pin to 2 x 40-pin connector.
Wire number 1 on the cable is red or blue, and the other wires are gray.
1. Connect one end of the cable to CN11. Make sure that the red (or
blue) wire corresponds to pin 1 on the connector, which is labeled on
the board (on the right side).
2. Plug the other end of the cable to the Enhanced IDE hard drive, with
pin 1 on the cable corresponding to pin 1 on the hard drive. (See your
hard drive’s documentation for the location of the connector.)
Connect a second drive as described above.
Unlike floppy drives, IDE hard drives can connect to either end of the
cable. If you install two drives, you will need to set one as the master and
one as the slave by using jumpers on the drives. If you install just one
drive, set it as the master.
2.9 Floppy drive connector (CN9)
You can attach up to two floppy drives to the PCM-9574’s on-board
controller. You can use any combination of 5.25” (360 KB and 1.2
MB) and/or 3.5” (720 KB, 1.44 MB, and 2.88 MB) drives.
A 34-pin daisy-chain drive connector cable is required for a dual-drive
system. On one end of the cable is a 34-pin flat-cable connector. On
the other end are two sets of floppy disk drive connectors. Each set
consists of a 34-pin flat-cable connector (usually used for 3.5” drives)
and a printed-circuit board connector (usually used for 5.25” drives).
