Bill, You are not supposed to delete the .DRV file from the hard drive. The video .DRV files work in conjunction with VESA drivers. You must run a VESA driver for your Trident card in order to get the high resolution. I would: 1. Reinstall the program so you have all the default files. 2. Find and run the VESA driver for your Trident card, prior to starting AAPRO. If you still get an error, then: 3: Diagnose for a memory conflict following the instructions below. -Brian Title: Clean system boot; diagnostics for memory conflict… Description: To confirm that the problem is caused by a memory conflict, re-start the computer with simplified settings (a 'stripped system') and see if the problem goes away. For DOS-only computers, a stripped system means that the computer is rebooted without terminate and stay resident (TSR) programs nor device drivers that are not absolutely necessary for the operation of the operating system and computer. The Autodesk program should also be configured for VGA display if possible, to rule out display driver conflicts. To reboot into a stripped system for 3D Studio and Animator Pro, change the system files as follows: CONFIG.SYS should contain only: FILES=40 BUFFERS=20 AUTOEXEC.BAT should contain only: PATH=<your path> PROMPT=<your prompt> You may want to use the DOS SYS command to create a bootable floppy for this trouble-shooting exercise and place these simplified system files on the diskette. Or, you may edit the existing CONFIG.SYS and AUTOEXEC.BAT files currently on the hard disk (make back-up copies first). Make sure you have a bootable DOS floppy on hand, just in case the computer has trouble rebooting. Note: Quarterdeck QEMM users may find it helpful to review the QEMM trouble-shooting documentation and use the Analyze utility to track down memory conflicts. Trouble-shooting: If the program now operates correctly, the next step is to determine which program or driver in your system files is causing the conflict. Edit the CONFIG.SYS and AUTOEXEC.BAT files, adding one device driver or TSR command at a time, rebooting, and starting 3D Studio/AAPRO until the error reappears. When the error happens, the last item you added to the configuration is probably the trouble maker. Once we know which drivers are conflicting, we can determine the proper course of action. If you are using special display adapters (for example, a Targa frame buffer), you should check the documentation that came with the display driver to see if special memory settings or EMS exclusions are needed.

>> I am using a Trident VGA card with 1Mb memory (it works GREAT with Soft Engine in AutoCAD and with the generic SVGA driver in Windows). However, When I delete the supervga.drv file from the resource subdirectory, I still cannot access the Screen Size option from the pull-down menu. I receive a page fault error, so I can not even try to select the VESA driver. << bill; Trident (ex:8900) is a bit tricky in that it doesn't have the "exact" same op codes as many other SVGA cards. the included SUPERVGA.DRV is not stable with it. i have a Trident 8900 myself which i love, but i have run into many programs in which the supplied VESA driver did not work with it. the solution has been the same every time…. get on Trident's BBS and download THEIR VESA driver (TSR). load it at AUTOEXEC time and you'll have no problems running it with most Adesk apps. Trident BBS is 415-691-1016. -dave
