Does anyone know whether there is a VGA card that supports non-interlaced 256 color 1024X768 mode (using 8-bit pixel) and uses linear mapping of its video memory at high memory address (above 1M, rather than a window between 0xa000 - 0xbfff)? Your help is greatly appreciated. Chain Lee chain@paul.rutgers.edu

Video-7's new VRAMII (should be in the stores by January) will do exactly what you want here. -- ...........>..........>........>......>...>...>..>..>..>..>.>.>.>>>>>>>>+ .

Unfortunately, it's only currently available on the latest high-end IBM MCA machines(I forget the model numbers). As for ISA cards, I believe that WD/Paradise and Video-7 have high-res non-interlaced VGAs, but I am not sure if the frame buffer can be mapped above 1 M. Does anybody know about this? If the cards do support this, is the access to the frame buffer paged, or can the entire contents of video memory be accessed linearly (in 386 protected mode environments)?
