While flashing the UEFI BIOS on my HP Angelica2 (M3970AM-MP aka M3970CMNR-HP) motherboard, my PC froze. After waiting a while, I powered it off and rebooted it. Now, upon power up, the PC just beeps and flashes 8 times and the monitor screen remains blank. According to a HP troubleshooting page, the 8 beeps/flashes mean a corrupt BIOS. I have tried clearing the CMOS, which did not make any difference. I will much appreciate any ideas or suggestions on how to recover from this. Thanks!
