Warning! Always completely disconnect the power cord
from your chassis whenever you work with the
hardware.Donotmakeconnectionswhilethe
power is on. Sensitive electronic components can

Caution! Always ground yourself to remove any static
chargebeforetouchingtheCPUcard.Modern
electronic devices are very sensitive to static
electric charges. As a safety precaution, use a
grounding wrist strap at all times. Place all
electronic components in a static-dissipative
surface or static-shielded bag when they are not
in the chassis.

Floppy drive connector (CN7), FPC (CN9)
You can attach up to two floppy drives to the mainboard controller.
Youcanuseanycombinationof 5¼"(360KBand1.2 MB)and/or
3½"(720KB,1.44MB,and2.88MB)drives.
A34-pindaisychaindriveconnectorcablefor(CN7)isrequiredfor
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 con-
nectors. Each set consists of a 34-pin flat-cable connector (usually
used for 3½" drives) and a printed-circuit board connector (usually
used for 5¼" drives). Plus an additional Flexible Printed Circuit
(FPC)connector(CN9),extradrivemeansextramemoryforyour
system. An ideal way for cost effective design.
Wire number 1 on the cable is normally red or blue, and the other
wiresareusuallygray.
Connecting the floppy drive
1. Plug the 34-pin flat-cable connector into CN7. Make sure that
the red or blue wire corresponds to pin 1 on the connector. No wor-
riesforCN9FPCconnector, it's guided design for error free con-
nection.
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 5¼" floppy drive, line up the slot in the
printed circuit board with the blocked-off part of the cable connec-
tor.
If you are connecting a 3½" floppy drive, you may have trouble
determiningwhichpinispinnumber1. Lookforanumberprinted
on the circuit board indicating pin number 1. Also, the connector
on the floppy drive connector may have a slot.When the slot is up,
pin number 1 should be on the right. Check the documentation that
camewiththedrivefor more information.Ifyoudesire,connectthe
B: drive to the connectors in the middle of the cable as described
above.
Please refer to the pin definitions on the next page.
