Ok..... today my Jetway Socket 370 mobo died. It gave me bleeps at startup and i've got the message: ROM bios checksum failed. Please insert floppy in Drive A. What the hell is that? It was my second pc, a PIII 1Ghz, 512mb SD-ram 133, MSI GeForce4Ti 4600 (AGPx4). That mobo supports AGPx4, but i have another mobo, let's say a replacement which supports only AGPx2. Will that be a big difference for a Ti4600 when running at AGPx2?
