Question : Problem: How do I disable parity check in AMI bios

My mobo only accepts parity ram and there is no option in the bios setup to change this. It is an ami bios (1.00.18.BI0) I need to know where in the bios image file are stored the default values written into the PCI registers to control this.

Then I can change the defaults and reflash the board.

PS My mobo is an intel altserver if that helps.

Answer : Problem: How do I disable parity check in AMI bios

First, nothing else in your PC uses the NMI line.  I'm suggesting that you probably can find the code in the BIOS that enables parity to be reported to the processor by looking for where the IO location 0x80 is controlled.  You keep talking about the "PCI" register, you are assuming that there is such a thing in your hardware.  Could it be that the reason your MB doesn't provide you a BIOS method of disabling parity is that the chipset used doesn't support this option?
