1.6 DDR SDRAM Installation
This motherboard supports a maximized 2GB DDR
SDRAM. It provides two184-pin unbuffered DDR sockets.
It supports 64MB to 1GB DDR memory module.
DDR SDRAM Installation Procedures:
1. The DDR socket has a “Plastic Safety Tab” and the DDR
memory module has an asymmetrical notch”, so the DDR
memory module can only fit into the slot in one direction.
2. Push the tabs out. Insert the DDR memory modules into the
socket at a 90-degree angle then push down the module
vertically to fit it into place.
3. The Mounting Holes and plastic tabs should fit over the
edge and hold the DDR memory modules in place.
Note: If you want to run FSB 533MHz on this Motherboard (with
133MHz CPU), you must use DDR 266MHz module because only
DDR 266 is able to support FSB 533MHz.

1.7.1.3 Serial Interface Port: COM1/COM2
The serial interface port is sometimes referred to as an RS232 port or an asynchronous communication port. Mice,
printers, modems and other peripheral devices can be
connected to a serial port. The serial port can also be used
to connect computer systems together . If you like to transfer
the contents of your hard disk to another system, it can be
accomplished with serial port.
COM1/2A
1.7.1.4 Parallel Interface Port
Unlike serial ports, parallel interface ports have been
standardized and should not present any difficulty interfacing
peripherals to your system. Sometimes called a Centronics
port, the parallel port is almost exclusively used with printers.
The parallel port on your system is a 25-pin, DB 25 connector.
1.7.1.5 Audio Port Connectors
Speaker out is a connector for Speakers or Headphones.
Line in is used for external CD player, Tape player, or other
audio devices. Mic is a connector for the microphones.

1.7.3 Floppy Disk Connector: FDD
This connector supports the provided floppy drive ribbon
cable. After connecting the single end to the board, connect
the two plugs on the other end to the floppy drives.
1.7.4 Hard Disk Connectors: IDE1/IDE2
These connectors are provided with IDE hard disk ribbon
cable into the package . After connecting the end of cable
with single connector to the mainboard, connect the other
two connectors at the other end to your hard disk. If you
install two hard disks, you must configure the second drive
to Slave mode by setting its jumper settings. BIOS now
supports SCSI device or IDE CD-ROM boot up (see "HDD

This allows the user to manually place the system into a suspend
mode of Green mode. System activity will be instantly decreased
to save electricity and expand the life of certain components
when the system is not in use. This 2-pin connector (see the
figure) connects to the case-mounted suspend switch. If you
do not have a switch for the connector, you may use the "Turbo
Switch” instead since it does not have a function. If you want
to use this connector, the "Suspend Switch" in the Power

is then stored in battery-backed RAM so that it can retain the
setup information after the power is turned off. The Award
BIOS installed in your computer system ROM (Read Only
Memory)is a custom version of an industry standard BIOS.
The BIOS provides critical low-level support for standard devices such as disk drives and serial and parallel ports. This
chapter is intended for guiding you through the process of
configuring your system BIOS.
Plug and Play Support
This AWARD BIOS supports the Plug and Play Version 1.0A
specification. ESCD(Extended System Configuration Data)
write is also supported.
EPA Green PC Support
This AWARD BIOS supports Version 1.03 of the EPA Green
PC specification.
PCI Bus Support
This AWARD BIOS also supports Version 2.1 of the Intel
PCI (Peripheral Component Interconnect)local bus
specification.

APM Support
This AWARD BIOS supports Version 1.1&1.2 of the
Advanced Power Management(APM) specification.Power
management features are implemented via the System
Management Interrupt(SMI). Sleep and Suspend power
management modes are supported. Power to the hard disk
drives and video monitors can be managed by this AWARD
BIOS.
DRAM Support
DDR SDRAMs (Double Data Rate SDRAM) are supported.
CPU Support
This AWARD BIOS supports the Intel P4 Processor.

system. PCI or Personal Computer Interconnect, is a system
which allows I/O devices to operate at speeds nearing the
speed of the CPU itself when communicating with the components on board. This section covers some very technical
items and it is strongly recommended that only experienced
users should make any changes to the default settings.

Reset Configuration Data
The system BIOS supports the PnP feature so the system needs
to record which resource is assigned and proceeds to get rid of
resource conflict. Every peripheral device has a node, which is
called ESCD (Extended System Configuration Data. This node
records which resources are assigned to it. If Disabled (Default)
is chosen, the system ESCD will update only when the new
configuration varies from the last one. If Enabled is chosen, the
system is forced to update ESCDs and then is automatically
reset to the “Disabled” mode.
Resources Controlled By
By Choosing “Auto” (default), the system BIOS will detect the
system resources and automatically assign the relative IRQ and
DMA channel for each peripheral. By choosing “Manual”, the
user will need to assign IRQ & DMA for add-on cards. Be sure
that no IRQ/DMA and I/O port conflict exists.
IRQ Resources :
Press Enter to configure the following Submenus

IRQ-7 assigned to : PCI Device
IRQ-9 assigned to : PCI Device

IRQ Resources
When resources are controlled manually, assign each system
interrupt a type, depending on the type of device using the
interrupt.
PCI / VGA Palette Snoop
Choose Disabled or Enabled. Some graphic controllers which
are not VGA compatible take the output from a VGA controller
and map it to their display as a way to provideboot information
and VGA compatibility.
However, the color information coming from the VGA controller
is drawn from the palette table inside the VGA controller to
generate the proper colors, and the graphic controller needs to
know what is in the palette of the VGA controller. To do this,
the non-VGA graphic controller watches for the write access to
the VGA palette and registers the snoop data. In PCI based
systems, the Write Access to the palette will not show up on the
ISA bus if the PCI VGA controller responds to the Write.
In this case, the PCI VGA controller should not respond to the
Write, it should only snoop the data and permit the access to be
forwarded to the ISA bus. The non-VGA ISA graphi controller
can then snoop the data on the ISA bus.Unless you have the
above situation, you should disable this option.
The choices: Disabled (default); Enabled
