I tried to flash the latest Beta Bios 1014beta3 on a Asus P2B-S (the Bios 1009 was installed).
I used Uniflash 1.33 and a USB Keyboard but the Keyboard won't work with uniflash, but also not with aflash.
In the readme of aflash I found the Part " ... if a the USB keyboard wont work, try a PS/2 to flash the latest version that should fix the Problem ..."
With a PS/2 keyboard I had no Problems with Uniflash.
@Rainbow could you put this Information in your Readme?
