This chapter gives information about the ASUS A7S266-VM Binary Input/Output System (BIOS).This chapter includes updating the BIOS using the ASUS AFLASH BIOS that is bundled with the support CD.
2.1 Managing and Updating your BIOS It is recommended that you save a copy of the motherboard’s original BIOS to a bootable floppy disk in case you need to reinstall the original BIOS later. 2.1.1 Using ASUS EZ Flash to update the BIOS The ASUS EZ Flash feature allows you to easily update the BIOS without having to go through the long process of booting from a diskette and using a DOS-based utility.
5. At the prompt, “Please Enter File Name for NEW BIOS: _”, type in the BIOS file name that you downloaded from the ASUS website, then press . EZ Flash will automatically access drive A to look for the file name that you typed. When found, the following message appears on screen. [BIOS Information in File] BIOS Version: A7S266-VM Boot Block WARNING! Continue to update the BIOS (Y/N)? _ If you accidentally typed in a wrong BIOS file name, the error message, “WARNING! File not found.” appears.
The BIOS information in the above screen is for reference only. What you see on your screen may not be exactly the same as shown. 2.1.2 Using AFLASH to update the BIOS Creating a bootable disk 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.
5. Select 1. Save Current BIOS to File from the Main menu and press . The Save Current BIOS To File screen appears. 6. Type a filename and the path, for example, A:\XXX-XX.XXX, then press . Updating the BIOS Update the BIOS only if you are sure that the new BIOS revision will solve your problems. Careless updating may result to more problems with the motherboard! 1.
6. When prompted to confirm the BIOS update, press Y to start the update. 7. The utility starts to program the new BIOS information into the Flash ROM. The boot block is updated automatically only when necessary. When the programming is done, the message “Flashed Successfully” appears. 8. Follow the onscreen instructions to continue. DO NOT turn off the system while updating the BIOS. This may cause boot problems.
2.2 BIOS Setup program Use the BIOS Setup program when you are installing a motherboard, reconfiguring your system, or prompted to “Run Setup”. This section explains how to configure your system using this utility. Even if you are not prompted to use the Setup program, you may want to change the configuration of your computer in the future. For example, you may want to enable the security password feature or make changes to the power management settings.
2.2.2 Legend bar At the bottom of the Setup screen is a legend bar. The keys in the legend bar allow you to navigate through the various setup menus. The following table lists the keys found in the legend bar with their corresponding functions.

Configuration options: [Off] [On] Keyboard Auto-Repeat Rate [12/Sec] This controls the speed at which the system registers repeated keystrokes. Options range from 6 to 30 characters per second.
PS/2 Mouse Function Control [Auto] The default setting [Auto] allows the system to detect a PS/2 mouse at startup. If a mouse is detected, the BIOS assigns IRQ12 to the PS/2 mouse. Otherwise, IRQ12 can be used for expansion cards. When you set this field to [Enabled], BIOS reserves IRQ12, whether or not a PS/2 mouse is detected at startup. Configuration options: [Enabled] [Auto] USB Legacy Support [Auto] This motherboard supports Universal Serial Bus (USB) devices.
The SDRAM parameters (items 2~5) become configurable only when you set the SDRAM Configuration to [User Defined]. SDRAM CAS Latency [3T] This item controls the latency between the SDRAM read command and the time the data actually becomes available. SDRAM RAS to CAS Delay [3T] This item controls the latency between the DDR SDRAM active command and the read/write command. SDRAM RAS Precharge Time [3T] This item controls the idle clocks after issuing a precharge command to the DDR SDRAM.
