1.5 CPU Installation

The motherboard operates with Socket 462 for AMD Athlon and Duron
TM
processor. The CPU should always have a Heat Sink
and cooling fan attached to prevent overheating.

CPU Installation Procedures for Socket 462

1. Pull the lever sideways away from the socket then raise the lever to a 90-degree angle.
2. Locate Pin 1 in the socket and look for the white dot or cut edge in the CPU. Match Pin 1 with the white dot/cut edge then insert the CPU.
3. Press the lever down to complete the installation.
4. Make sure the spec of the cooling fan is good enough.
5. Please lock the fan on CPU very carefully, or you will damage the resistor array even circuit line on the mainboard.

1.6 DDR SDRAM Installation

The motherboard supports a maximized 3GB memory. It pro­vides three 184-pin unbuffered DDR sockets and each 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 vertically to fit onto place.
3. The Mounting Holes and plastic tabs should fit over the edge and hold the DDR memory modules in place.

1.7.1.3 Serial Interface Port: COM1/2

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.
COM1/2

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 Ports

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.

2. BIOS Setup

2.1 BIOS Support

This chapter discusses the Award BIOS Setup program built in the ROM BIOS. The Setup program allows the user to modify the basic system configuration. The modification 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.

Chapter 2 7KT400A BIOS Setup
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 (Double Data Rate) are supported.
Setup Menu
In general, you use the arrow keys to highlight items of the Main BIOS Setup Menu, press <Enter>to select, use the <PgUp>and <PgDn>keys to change entries, press<F1>for help and press <Esc> to quit The following table provides more detail about how to navigate in the Setup program by using the keyboard.
Note:
BIOS version 1.0 is for reference only. If there is a
change in BIOS version, please use the actual version
on the BIOS.

2.5 Advanced Chipset Features

This section allows you to configure the system based features of the installed chipset. This chipset manages bus speeds and access to system memory resources, such as DRAM and external cache. It also coordinates communica­tions of the PCI bus. It must be stated that these items should never be altered. The default settings are set up to provide the best operating conditions for your system. The time you might need to make any changes would be if you discover that data is lost while using your system.

2.8 PnP/PCI Configurations

This section describes configuration of the PCI bus 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.

Chapter 2 7KT400A BIOS Setup
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(ESCD)” , 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.
X IRQ Resources :

Chapter 2 7KT400A BIOS Setup
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
