IBM 100/10, PCM-9575 user manual Solid State Disk, Floppy drive connector CN18, CompactFlash CN26

(See your hard drive’s documentation for the location of the con- nector.)

If desired, 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 only one drive, set it as the master.

2.9 Solid State Disk

The PCM-9575 provides a CompactFlash™ card socket and DiskOnChip socket for Solid state disk solutions.

2.9.1 CompactFlash (CN26)

The CompactFlash card shares a secondary IDE channel which can be enabled/disabled via the BIOS settings.

2.10 Floppy drive connector (CN18)

You can attach up to two floppy drives to the PCM-9575’s on-board con- troller. 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.

A34-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).

2.10.1 Connecting the floppy drive

1.Plug the 34-pin flat-cable connector into CN18. Make sure that the red wire corresponds to pin one on the connector.

2.Attach the appropriate connector on the other end of the cable to the floppy drive(s). You can use only one connector in the set. The set on the 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 5.25” floppy drive, line up the slot in the printed circuit board with the blocked-off part of the cable connec- tor.
