#NT3.5 Memory Addresses

The Stealth 64 DRAM uses the memory range C000-C800 for the Video BIOS. In Standard VGA mode it uses the range A000-AFFF for the Video Buffer. In text mode it uses the range B800-B7FF for the text buffer. Our card does not normally use memory in the Fxxx range. If this memory is being used by video then it is being mapped by the driver and not our card specifically. These could be IO address and not memory addresses that are causing the problem. What is the error message that you are getting from Windows NT? Is this a PCI system or a VLB system? Is the net work card ISA or PCI? What version of the BIOS do you have on your Stealth card? –Wayne Johnson Diamond Multimmedia Systems' ES Dept.

Wayne, thank you for you response. The bios on my Stealth card is dated 7/01/94 and I am using a ISA SMC card. I have inadvertently solved my problem by moving one of the SMC card drivers into my WFWG Windows directory. NT now shows Video0 at 0xA0000 and Video0 at 0xC0000 and my my SMC card at 0xC8000. I don't know why it works now but it does. The Stealth video is great. Thanks. A. Stone
