BIOS setup

ASUS P4S133 motherboard

Managing and updating your BIOS
4.1.1 Using the computer system for the first time
It is recommended that you save a copy of the original motherboard BIOS along with a Flash Memory Writer utility (AFLASH.EXE) to a bootable floppy disk in case you need to reinstall the BIOS later. AFLASH.EXE is a Flash Memory Writer utility that updates the BIOS by uploading a new BIOS file to the programmable flash ROM on the motherboard. This file works only in DOS mode. To determine the BIOS version of your motherboard, check the last four numbers of the code displayed on the upper left-hand corner of your screen during bootup. Larger numbers represent a newer BIOS file. 1. Type FORMAT A:/S at the DOS prompt to create a bootable system disk. DO NOT copy AUTOEXEC.BAT and CONFIG.SYS to the disk. 2. Type COPY D:\AFLASH\AFLASH.EXE A:\ (assuming D is your CD-ROM drive) to copy AFLASH.EXE to the boot disk you created.
AFLASH works only in DOS mode. It does not work in the DOS prompt within Windows and does not work with certain memory drivers that may be loaded when you boot from the hard drive. It is recommended that you reboot using a floppy disk.
3. Reboot the computer from the floppy disk.
BIOS setup must specify Floppy as the first item in the boot sequence.
4. In DOS mode, type A:\AFLASH <Enter> to run AFLASH.
If the word unknown appears after Flash Memory:, the memory chip is either not programmable or is not supported by the ACPI BIOS and therefore, cannot be programmed by the Flash Memory Writer utility.
5. Select 1. Save Current BIOS to File from the Main menu and press <Enter>. The Save Current BIOS To File screen appears.
6. Type a filename and the path, for example, A:\XXX-XX.XXX, then press <Enter>.

Because the BIOS software is constantly being updated, the following BIOS setup screens and descriptions are for reference purposes only, and may not exactly match what you see on your screen.

Before you proceed

Take note of the following precautions before you install motherboard components or change any motherboard settings.
1. 2. Unplug the power cord from the wall socket before touching any component. Use a grounded wrist strap or touch a safely grounded object or to a metal object, such as the power supply case, before handling components to avoid damaging them due to static electricity. Hold components by the edges to avoid touching the ICs on them. Whenever you uninstall any component, place it on a grounded antistatic pad or in the bag that came with the component. Before you install or remove any component, ensure that the ATX power supply is switched off or the power cord is detached from the power supply. Failure to do so may cause severe damage to the motherboard, peripherals, and/or components.

3. 4. 5.

When lit, the green LED (SB_PWR1) indicates that the system is ON, in sleep mode, or in soft-off mode, a reminder that you should shut down the system and unplug the power cable before removing or plugging in any motherboard component.

Central Processing Unit (CPU)

1.8.1 Overview

The motherboard comes with a surface mount 478-pin Zero Insertion Force (ZIF) socket. The socket is designed for the Intel Pentium 4 Processor in the 478-pin package with 512/256KB L2 cache on 0.13 micron process. This processor supports 533/400MHz front side bus (FSB), and allows data transfer rates of 4.2GB/s and 3.2GB/s. Note in the illustration that the CPU has a gold triangular mark on one corner. This mark indicates the processor Pin 1 that should match a specific corner of the CPU socket.

Gold Mark

Incorrect installation of the CPU into the socket may bend the pins and severely damage the CPU!
Intel Hyper-Threading Technology is not supported in this motherboard.

1.8.2 Installing the CPU

Follow these steps to install a CPU. 1. Locate the 478-pin ZIF socket on the motherboard. 2. Unlock the socket by pressing the lever sideways, then lift it up to a 90100 angle.

Socket Lever

90 - 100
Make sure that the socket lever is lifted up to 90-100 angle, otherwise the CPU does not fit in completely.
3. Position the CPU above the socket such that its marked corner matches the base of the socket lever. 4. Carefully insert the CPU into the socket until it fits in place.
The CPU fits only in one correct orientation. DO NOT force the CPU into the socket to prevent bending the pins and damaging the CPU!
5. When the CPU is in place, push down the socket lever to secure the CPU. The lever clicks on the side tab to indicate that it is locked. 6. Install a CPU heatsink and fan following the instructions that came with the heatsink package. 7. Connect the CPU fan cable to the CPU_FAN1 connector on the motherboard.

1.10.2 IRQ assignments for this motherboard
A B C D E PCI slot 1 used PCI slot 2 shared PCI slot 3 shared AGP slot shared Onboard USB controller 1 used Onboard USB controller 2 Onboard USB controller 3 Onboard USB 2.0 controller Onboard LAN (optional) shared Onboard audio shared Onboard VGA shared F used G H used used
When using PCI cards on shared slots, ensure that the drivers support Share IRQ or that the cards do not need IRQ assignments. Otherwise, conflicts will arise between the two PCI groups, making the system unstable and the card inoperable.

Jumpers

1. USB device wake-up (3-pin USBPWR_12, USBPWR_34, USBPWR_56) Set these jumpers to +5V to wake up the computer from S1 sleep mode (CPU stopped, DRAM refreshed, system running in low power mode) using the connected USB devices. Set to +5VSB to wake up from S3 sleep mode (no power to CPU, DRAM in slow refresh, power supply in reduced power mode). Both jumpers are set to pins 1-2 (+5V) by default because not all computers have the appropriate power supply to support this feature. The USBPWR_12 and USBPWR_34 jumpers are for the rear USB ports. The USBPWR_56 jumper is for the internal USB header that you can connect to the front USB ports.
1. This feature requires a power supply that can provide at least 1A on the +5VSB lead when these jumpers are set to +5VSB. Otherwise, the system would not power up. The total current consumed must NOT exceed the power supply capability (+5VSB) whether under normal condition or in sleep mode.

+5V (Default)

2. Clear RTC RAM (CLRTC1) This jumper allows you to clear the Real Time Clock (RTC) RAM in CMOS. You can clear the CMOS memory of date, time, and system setup parameters by erasing the CMOS RTC RAM data. The RAM data in CMOS, that include system setup information such as system passwords, is powered by the onboard button cell battery. To erase the RTC RAM: 1. Turn OFF the computer and unplug the power cord. 2. Remove the onboard battery. 3. Move the jumper cap from pins 1-2 (default) to pins 2-3. Keep the cap on pins 2-3 for about 5~10 seconds, then move the cap back to pins 1-2. 4. Replace the battery. 5. Plug the power cord and turn ON the computer. 6. Hold down the <Del> key during the boot process and enter BIOS setup to re-enter data.
