Q
WAKEUP-LINK Header
The Mainboard provides a WAKEUP-LINK header used to con-
nect an add-in NIC (Network Interface Card) which has Wake-
on-LAN capability.
S
CPU Card Slot 1
The Mainboard provides a 242-pin CPU slot for use with Intel
Pentium II / III processor. The CPU should have a fan attached
to it to prevent overheating. If a fan is not present, a fan should
be installed prior to turning the system on.
T
CPU Fan Connector
The recommended heatsinks for the processor are those with 12
Volt three-conductor fans that can be connected to the fan connec-
tor on the mainboard. Pr12 Volts DC to the CPU cooling fan
as follows:
PIN
SIGNAL NAME
1
(CPU FAN Rotation Signal)
2
+12V
3
Ground
CAUTION! Be sure that sufficient air circulation is available across the
processor’s heatsink by regularly checking that your CPU fan is work-
ing. Without sufficient circulation. the processor could overheat and
damage both the processor and the mainboard. You may install an
auxiliary fan if necessary.
N
Flash BIOS
The Mainboard flash BIOS provides users with more flexibility
in upgrading their mainboards. The flash BIOS can be easily
reprogrammed via software.
O
Floppy Drive Connector
The Mainboard provides a 34-pin connector that supports the
included floppy drive ribbon cable. After connecting the single
end to the on-board “FLOPPY” connector, connect the remain-
ing plugs on the other end of the cable to the corresponding
floppy drives.
NOTE: Pin 5 is removed to prevent inserting the connector in
the wrong orientation.
P
IDE Device Connector
The Mainboard provides (2) independent bus-mastering PCI
IDE interfaces capable of supporting up to Mode 4 and Ultra
DMA-33 devices. The system BIOS supports automatic detec-
tion of the IDE device data transfer rate and translation between
different kinds of device modes such as Logical Block
Addressing (LBA), Extended Cylinder Sector Head (ECSH)
translation modes and ATAPI (e.g., CD-ROM) devices on both
IDE interfaces.
The two on-board IDE connector support the provided 40-pin
IDE hard disk ribbon cables. After connecting the single end to
the mainboard connector, connecting the two remaining plugs at
the other end of your hard disk(s) and/or CD-ROM drive(s). If
you install two hard disks and/or CD-ROM drives, you must con-
figure the two drives by setting their IDE master/slave jumpers
according to the documentation for those devices.
Also, you may connect the two hard disk drives so that both
become Masters, using one ribbon cable on the primary IDE
connector and one on the secondary IDE connector.
