Ok!
In Bios -> Boot device priority: you must set the Floppy drive the 1st, then the HDD.
This is what you have to do!
Unzip the xxxxx.bin (1007.bin for ex)
Copy that .bin file to a blank floppy disk.
Download the awdflash utility from Asus website -> awdflash.zip
Unzip it too and copy it to the mentioned floppy disk! So you have in that floppy the awdflash.exe and the .bin bios file.
Now reboot your system and introduce the floppy before the POST.
When A:\ appears, type awdflash and press enter
Then a new window should appear, there you have to type the name of the .bin file you copied into your floppy.(Example: 1007.bin in your floppy,ok?, so you have to type 1007.bin in that window)Press enter
When the program asks you to start programming, accept it by pressing Y, and when it asks you to save the old bios file say No (N).
It will rewrite your Bios file. Wait until finish!
Done!
Remove the floppy disk
