i have installed many a win 98 to XP system but baffled by this one.
card has all the markings as per the subject but any attempt to install the drives to change it from a standard VGA adapter cause it to reject the drivers saying its not an nvidia card.
also i have an old PCI Matrox g400 and that refuses saying "This operation has been cancelled due to restrictions in effect on this computer. Please contact your system administrator." when i try to run the install program.
never seen this on a 98 system.
