Tha case of AWARD BIOS
If the self-extract file in step.4 extracts the .BIN file only (step 4.a, 5.a) , excute awdflash.exe by this way please.
A:\>awdflash BD72_AJ.BIN /py /sn /cd /cp /cc /cks /R
Otherwise the self-extrat file should extract 5 files which including runme.bat (step 4.b, 5.b). Just execute runme.bat by typing "runme" and enter.

A:\>AMIFLASH SR7_A8.ROM
or execute RUNME.BAT by typing "RUNME" and enter.

Switch off the power supply unit or pull off the power cord. There is a CCMOS jumper near the battery. Change the jumper position from default 1-2 to 2-3 for one minute to discharge the CMOS data, and then put it back to default 1-2. Switch on the power supply unit or pull in the power cord. Press the power-on button to boot up system. If it works, hit "Del" key to enter the BIOS setup page to do correct settings.
