5. Connecting Front Panel Cable
Attach the power LED, speaker, and reset switch
connectors to the corresponding pins. If you enable
"Suspend Mode" item in BIOS Setup, the ACPI &
Power LED will keep flashing while the system is in
suspend mode.
Locate the power switch cable from your ATX
housing. It is 2-pin female connector from the housing
front panel. Plug this connector to the soft-power
switch connector marked SPWR.
6. Connecting IDE and Floppy Cable
Connect 34-pin floppy cable and 40-pin IDE cable to floppy connector FDC and IDE
connector. The blue connector is IDE1 for clear identification. Be careful of the pin1
orientation. Wrong orientation may cause system damage.

This motherboard has three 168pin DIMM sockets
that allow you to install system memory up to
1.5GB. SDRAM, VCM SDRAM, Registered
SDRAM are supported.
Tip: The driving capability of new generation
chipset is limited due to the lack of a memory buffer
(to improve performance). This makes DRAM chip
count an important factor to take into consideration
when you install DIMMs. Unfortunately, there is no
way that the BIOS can identify the correct chip
count, you need to calculate the chip count by
yourself. The simple rule is: By visual inspection,
use only DIMMs which are less than 18 chips..

The CD-IN connector is used to connect CD
Audiocable from CDROM or DVD drive to
onboard sound.
The Modem-CN connector is used to connect
Mono In/ Mic Out cable from internal modem
card to onboard sound circuit.
