This is the newest driver (even though new is a relative term) for the trident 3dIma'ge 9750 copyright 97'. this is from the trident website, and it does work and it does support upt 1024X768 at 32 bits. Note that most of the others on this site are for the old Aptiva's from IBM. they will not support over 256 color at 800x600 even if the card can. Im using this particular card in an old workstation and it has 4mb of ram. Aptivas only had 2mb. so if yours sounds closer to this I hope this helps.
The following files are found inside the driver download file.
