I have an old 650 AThlon powered PC that I've just formatted. I now find that the Mainboard CD has been lost in the mists of time. The Mobo book says it's a Slot A M800LMR. I need the CD to install the PCI-ISA bridge driver so that the board see the PCI, AGP devices. I've looked Hi and low for the disc and searched Driverguide.com for the relevent drivers but end up going around in circles. The nearest I can is a reference to an M810 board. I beleive the driver that I need is (amd-756 pci-isa bridge driver)unless you know differently. Any advice/help is much appreciated as the PC is running on 256 colour and 640 x 480. It has an ATI Fury Maxx graphics card. My wife uses this PC to unwind with Majong and card games mainly, she's looking after me so it's critical guys.
