Who knew this stuff could be so complicated? I almost bought one of those IBM oem cards myself. Glad I missed it. We're lucky to have this resource to answer these questions.
To install these, do I simply uninstall the old drivers, and then reboot so the system knows to look for new drivers, or is there a utility on the XP disk where I can tell it to install drivers? Thanks, Jay
Start/Control panel/System/hardware/Device Manager Expand the Display Adapters Right click and select Properties Select Driver Update Driver. There's probably a faster way, but this is the one I always remember.
Matrox recommends you uninstall the old driver. You can use their powerdesk uninstaller from here - http://www.matrox.com/mga/support/drivers/files/ftp_util2.cfm After you reboot, you might want want to go onto Microsofts update sight. It will automatically detect latest certified driver needed. This is what I ended up doing. The latest set of drivers wouldn't work, didn't want to see the secondary PCI monitor.
I agree with those saying to avoid the Matrox drivers. I have never gotten them to work properly. Just uninstall them and then reboot. XP will do the rest. I have been running on the XP default drivers for almost a year with no problems.
