I have an HP Pavillion A1720N that I tried to update the BIOS with sp37378. During the update process(a windows bios flash), the system froze. I waited for several hours just to make sure it would comeback but not. I recycled the power and now I get Award BootBlock BIOS v1.0 Copyright (c) , Award Software, Inc. BIOS ROM checksum error SP37378 is supposed to flash the BIOS to version 5.23. The system was at version 5.21 before I started. I have created a DOS boot CD and have tried several version of awdflash.exe with rom file 523.rom as well as 521.rom but I get error message “Unknown Flash Type” The system is 13 months old so just out of warranty. Called HP support and after a $50 Support call they want to sell me a new MOBO for $315.00 or a new system. Seems to me there should be a way to reflash the BIOS rom. The MOBO is a ASUS P5LP-LE (Leonite) with Award BIOS any help would be greatly appreciated
