i have a abit bd7 board which is giving me an A7 error code on the lcd during POST. does anyone know what this means as it is not in the manual? Also, the board used to work, but now it stopped. Any suggestions will be greatly appreciated....

from ami bios: A7= NMI and parity enabled. Going to do any initialization required before giving control to optional ROM at E000.

The BD7 has Award BIOS and the A7 error is misleading because in order to have a halt at NMI and Parity enabled would mean that you have to at least have a partially functioning board. I don't know if you have tried this but pull the AGP video card out and insert a PCI vid card or just leave it with no Video card. Turn on the system and check to see if the post code changes to something like 88. If it does than your AGP vid card or AGP slot is bad and unfortunatly so is the ICH2 controller. Seen it many times when a non-compliant AGP Card is inserted into the boards AGP Slot. The 845 chipset will only take a 1.5 volt AGP vid card and older cards will destroy the board. Hopefully you just have a bad Video card.
