2.8 CompactFlash™ disk (CN24)
The PCM-5825 is equipped with a CompactFlash disk socket on the
solder side and it supports the IDE interface CompactFlash disk
card. The socket itself is especially designed to prevent any
incorrect installation of the CompactFlash disk card. When
installing or removing the CompactFlash disk card, please make
sure that the system power is off.
The CompactFlash disk card is defaulted as the E: disk drive in
your PC system.
2.9 Floppy drive connector (CN4)
You can attach up to two floppy drives to the the PCM-5825 on-
board controller. Any combination of 5¼” (360 KB and 1.2 MB)
and/or 3½” (720 KB, 1.44 MB, and 2.88 MB) drives is possible.
A 34-pin daisy-chain drive connector cable is required for a dual-
drive system. A 34-pin flat-cable connector is fitted on one end of
the cable while the other end sports two sets of floppy disk drive
connectors. Each set consists of a 34-pin flat-cable connector (for
the 3½” drives) and a printed-circuit board connector (for the 5¼”
drives).
2.9.1 Connecting the floppy drive
1. Plug in the 34-pin flat-cable connector into CN4. Make sure that
the red wire corresponds to pin 1 on the connector.
2. Attach the appropriate conector at the other end of the cable to
the floppy drive(s). You can use only one connector in the set.
The set at the other end (after the twist in the cable) connects to
the A: drive. The set in the middle connects to the B: drive.
3. If you are connecting a 5¼” floppy drive, line up the slot in the
printed circuit board with the blocked-off part of the cable
connector.
When connecting a 3½” floppy drive, you may have some
difficulties in determining which pin is pin number one. Look for a
number on the circuit board indicating pin number one. In addition,
