Pins [2&4] ACPI-LED:
For ACPI LED connection on the case.
Pins [5&7] RESET:
Connects to the reset button on the case. The reset button is
used to “cold-boot” the system without actually turning off the power, reducing
wear and tear on the power supply. Avoid rebooting the system when the HDD
LED is blinking.
Pins [6&8] PW_SW:
Allows connecting to the power button on the case.
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. Always lit when system power is on.
Pins [2&4&6&8] SPEAKER:
Connects to the speaker on 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. Normally it’s
recommended that you
connect your first hard
drive to the Primary
port, and the first
CD-ROM to the Secondary.
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.
Floppy Disk Connector (FLP1)
The on-board floppy controller supports 2 floppy disk drives. Make
sure the RED stripe on the ribbon cable is oriented towards Pin-1.
