FP2:
Pins [1 & 3] KEYLOCK:
Keyboard lock switch lead. It connects to the
case-mounted keylock switch, allowing you to disable the keyboard function for
security purpose.
Pins [5 & 7 & 9] PW-LED:
Power LED. It is always lit when the system power
is on.
Pins [2 & 4 & 6 & 8] SPEAKER:
Connects to the speaker on the system’s
case.
Hard Disk Connector
The on-board Enhanced IDE controller can support up to 4 IDE hard
drives or other ATAPI devices, such as CD-ROMs. This controller, as
with all Enhanced IDE controllers, consists of both Primary (IDE 1)
and Secondary (IDE 2) ports. Each port has an associated connector
and cable, which can support up to 2 ATAPI devices each.
All IDE devices have jumpers, which allow the user to configure the
device as either “Master” or “Slave”. A Master device is one that is
ALONE on the IDE cable, whereas a Slave device is installed as a
SECOND device on the same cable. Keep in mind that the Master
device will appear before the Slave device in the CMOS Setup, as
well as the Operating System software. *Refer to the device
documentation for jumper settings.
The Secondary IDE
port can be used for
up to 2 additional
ATAPI devices.
Make sure to align
the RED stripe on the
ribbon cable with
Pin-1 on the
motherboard IDE connector. On most hard drives and CD-ROMs, the RED stripe
should be oriented towards the power connector of the device.
When using Ultra ATA 66/100 IDE cable (as shown above), the black color
connector on the cable is for Master drive, gray color is for Slave drive and blue
color is for connecting to IDE port onboard.
Note that Ultra ATA 66/100 devices must be connected to IDE2 (the blue
connector).
Floppy Disk Connector (FDD)
The on-board floppy controller supports 2 floppy disk drives. Make sure
the RED stripe on the ribbon cable is oriented towards Pin-1. Notice the
“twist” between the sets of connectors on the floppy cable. The floppy
drive “A” position is at the END of the cable, whereas floppy drive “B” is
hooked to one of the connectors on the other side of the twist.
