Awdflash.exe refreshing the motherboard BIOS program

why upgrade the motherboard BIOS

In the process of using computers, we often encounter some hardware incompatibilities, such as Windows XP flower screen or sound card can not be audible, motherboard and new hard disk incompatible, some of which can be resolved by updating the BIOS. Due to the continuous updating of hardware technology, the motherboard official will provide the latest BIOS version to provide users with updates, updated BIOS free access to new features and hardware technical support, such as support high-speed hard disk interface Ultra ata/66/100, more than 128MB of large memory, the new CPU. And the new version of the BIOS will generally fix many of the older versions of the bug.

Hardware Master In addition to regularly update their love machine BIOS files, but also to personalize the BIOS, such as the addition of personal information or plug-in, power off the logo. This time Awdflash.exe will be able to do their own.

　　BIOS Type Overview

Currently on the market motherboard BIOS mainly has award BIOS, AMI BIOS, Phoenix bios three types, and the award BIOS is developed by Award software company BIOS, is the motherboard BIOS is the most widely used BIOS, This information can be found in the first line of the boot information, such as "award Modular BIOS v4.51g" tells us that this is the award BIOS, the version is 4.51, you just download the corresponding motherboard model of the latest version of the BIOS file from the Internet, Run the Awdflash.exe from the floppy disk in pure DOS, then follow the prompts to complete the motherboard BIOS update, in general this process will not be more than two minutes can be done.

Theoretically, the same as upgrading the motherboard BIOS and upgrading the hardware driver, if you do exactly the right steps, there is usually no accident. However, it is possible to encounter the following conditions:

1. A power outage occurred during the writing of the new BIOS.

2. There are bad blocks on the boot floppy for the upgrade.

3, the Refresh program forcibly refreshes the Bootblock (boot module).

4, the BIOS file itself damaged, such as infected with the virus.

If you encounter one of these conditions, the BIOS update will fail, if the failure of what to do, this time Awdflash.exe will be able to work again, I have told you about the Awdflash parameters, in the upgrade BIOS using the/SB parameter, This way the upgrade program will forcibly skip the refresh of the Bootblock (boot module) in the motherboard BIOS. Only after using the/SB parameter when upgrading the BIOS can we recover the pre-upgrade BIOS data with an bootblock that is not compromised, or it may not be recoverable. Even if you have an emergency recovery disk in your hand, it will not work.

All we need to do is start the system with a copy of the boot disk with Awdflash.exe and *.bin (preferably a Autoexec.bat file with "Awdflash.exe *.bin/sn/py" in the floppy disk, so you can avoid the hassle of blind operation or looking for the ISA graphics card. If the bootblock is not destroyed, we can see the floppy drive light is on, and the floppy disk drive is also reading the disk, after the lights out, the BIOS recovery, if successful, after restarting will be OK.
