CNR Slot
A Communication Networking Riser (C.N.R.) slot can be fitted with CNR MODEM, or
MODEM/ LAN 10/100M card.
USB interface
With support for up to 4 USB Ver. 1.1 ports, two on-board, this motherboard provides
ample USB expansion room.
IDE interface
This motherboard comes with an onboard PCI Bus Master IDE controller with two
connectors that support four ATA66/ 33 devices on two channels. Supports UDMA/66,
UDMA/33, PIO Modes 3 & 4 and Bus Master IDE DMA Mode 2, and Enhanced IDE
devices, such as CD-R/ RW, DVD-ROM, CD-ROM, Tape Backup and LS-120 drives. An
IDE-3/4 RAID function is optional.
Super Multi-I/O
This functionality is integrated into the southbridge of the chipset. It provides two high-
speed UART compatible serial ports and one parallel port with EPP and ECP capabilities.
Infrared (IrDA) Connector
This functionality is also integrated into the southbridge of the chipset. The IrDA connector
supports an optional IR remote control device for wireless interfacing with external
peripherals, personal gadgets, or an optional remote controller.
System BIOS
This motherboard comes with a 2MB BIOS that provides CPU/ SDRAM frequency, boot
block write protection, and HD/ SCSI/ CD/ Floppy boot selection. DMI is also supported
through BIOS, which allows hardware to communicate within a standard protocol creating
a higher level of compatibility.
Special Function
A. Over 300W P4 type power supply is needed, meanwhile over 250W PIII type
power supply is acceptable but not guaranteed for proper function.
B. Provides CPU over-clocking up to 133MHz by BIOS setting but not guaranteed
for this function. Vendor is not Responsible for any damage on CPU or main
board due to the over-clocking failure (Jump cap to “2-3” of JP6 to reset BIOS if
over-clocking fails).
C. AC-97 Sound Codec chip provides “ amplifier“ function.
D. Optional IDE 0/1 RAID function by using “PROMISE“ PDC 20265R chipset.
Only 4X AGP is acceptable.
