Using the Boot Block to recover the motherboard BIOS

Computer store news Upgrading the motherboard BIOS has always been considered a difficult DIY operation by friends, so many novices do not dare to upgrade the BIOS. In fact, as long as you follow the correct steps, the BIOS upgrade is not terrible. But what happens once the upgrade fails? Here is a more common way to rescue newcomers after upgrading the motherboard BIOS.

There are some motherboards (mainly motherboards that use Award BIOS). There is a Boot Block in the BIOS. Generally, the BIOS will not be overwritten when upgrading the BIOS. Some motherboards are also writing new ones. The BIOS file asks for the Update BIOS Including Boot Block and ESCD (for security reasons, it is best to select “N”). If the Boot Block is not corrupted, we can use it to restore the original BIOS.

However, the Boot Block in the BIOS only supports the most basic hardware such as floppy disk drive and ISA graphics card. If the graphics card is AGP or PCI interface, it can only operate blindly during operation (now some motherboard BIOS boot) Block also supports PCI graphics), but the floppy drive can still read the disk normally. If you are not sure about the blind operation, you can also make an emergency recovery disk in advance, in addition to copying into awdflash.exe and *.bin two files, then create an Autoexec.bat file, the content is as follows: awdflash.exe *.bin /sn /py

“sn” means not backing up the old BIOS file, so you can avoid the operation of pressing the “N” key once”; “py”; represents the automatic completion of the BIOS refresh task.

This will allow you to use this boot disk to automatically recover the damaged BIOS. However, I have a special reminder to you: now the Awdflash.exe program after version 7.0 will refresh the Boot Block on the motherboard by default, so if you want to save the Boot Block, you must use the /sb parameter when upgrading the BIOS, this will force Skip this module, this is a good thing to remember.
