Gateway's OEM MS-6330 v2.1 mainboard

If you go motherboard hunting on EBay, you may run across a lot of these OEM boards. They have a Gateway AMI BIOS, MS-6330 v2.1 printed on the board, and a custom case front panel connector header. The reason you run across a lot of them is because they were manufactured with defective CPU filter capacitors; the aftermarket has been replacing the capacitors and reselling the boards.

The boards shipped with a BIOS that is full of bugs. The 0AAVWP02 BIOS (8/21/2000) most annoyingly has a bug that causes a corrupted IRQ routing table when a PS/2 mouse is not connected. Linux does not handle this corrupted IRQ routing table, and crashes at boot as in this bug report:

But, though this is a MSI board (similar to K7T Pro), you cannot use a MSI BIOS on it (MSI does not mention a MS-6330 v2.1 on their site). The key to knowing how to find this BIOS is to know that Gateway's code name for the board is “Oxnard”. Then you can go here: in order to download the BIOS (7511677.exe 2/17/2003) The latest BIOS is 0AAVWP13.

If you are trying to figure out how to hook up the front panel or other connectors on the motherboard, go here:

    Thank you so much for this information, I’ve had this board sitting for a couple years because of the bad caps near the cpu socket and it was nice to find your article with the right links and correct information. Hope everyone else finds this article as helpful as I did.
