Only info I could find on the XP driver install
Windows XP Driver Install.
Install the card into the AGP or PCI express slot. The card must be installed to install the drivers.
If Windows displays a message "New Hardware Found" you MUST quit this and not let the standard Windows drivers install.
If your PC has previously had any ATI card installed, you will need to remove the existing ATI drivers. Do this by downloading and running this utility:
Start (or restart) Windows. The Windows screen should be displayed at 640 X 480 interlaced, 16 colours. To use the ArcadeVGA built-in modes the ATI driver needs installing. Insert the Ultimarc CD. Run the driver Setup program in the correct folder (XP). Reboot as prompted.Windows may ask if you want to replace newer files with old. You MUST choose to replace all the files.
Right-click on the desktop, select "properties" and set the colour depth to "32 bit colour".
Blue Screens in XP Windows XP may try to invoke the built-in Microsoft ATI driver and this will not work with the ArcadeVGA card, and causes a blue-screen error. If you see this ,re-start and hold down "F8" and choose to start in Safe Mode, then install the ATI driver from the ArcadeVGA CD. To do this, you will need to enter device manager, right click on the expanded video card listing under 'Display Adapters' (or, the undesignated option, if the device has not been recognized at all, and has a yellow X next to it), clickon properties, go to driver tab, and click on 'update driver'. This is the only way to install the driver in safe mode, as attempting to install via ATI's setup utility will produce error messages and result in a failure to install. You will need to point the driver install to the correct location on the CD as mentioned in "Forcing a driver install", further down this page.
