Have a motherboard here that is exibiting the same symptoms as this AW on youtube
It seems to have a split personality as it is a phoenix bios but the crisis disk option to start the mode is CTRL & Home
I had the 4bit colour issue with the AW .07w bios so rolled back to the 2.06w which cured it. However the next day it started doing the beep/reboot thing in the clip.
My assumption is it is a bad flash but crisis recovery seems to make no difference, just some bios versions do not give the muted repeated beep after the initial one.
I have done the usual swap ram, cpu, no hdd or dvd & pcie checked gfx card in another machine but all are good.
Is there a .cfg file format that can be used in conjunction with phlash16 to pass the command line switches? particularly /C Clear cmos and /Z zero block before erase.
