The AF53.exe is the lastest Flash BIOS programer from Award(R). 
Award(R) has suggested a way to recover the BIOS in case of failure
during the flash BIOS programing. 

How to restore BOOT BLOCK BIOS.

To restore a boot block BIOS, you need the following:

1. A floppy disk drive connected to the target system.

2. One bootable disk with the following files:
	
	@ The Award(R) flash BIOS program(afxx.exe, which xx is the version number).
	
	@ An BIOS binary for your board, so PLEASE SAVE the old BIOS file
	  during the BIOS upgrade.

	@ Autoexec.bat file containing the line afxx.exe saved old BIOS file name /Py /Sn.

3. Optional ISA/VESA VGA card in the target system. 

Hopefully This can give you out of tough spot. (for further information please
go to Award(R)'s web site at www.award.com.
