I have a Ventura 16-bit VGA card with 1MB of video memory. However, when I
try to display a resolution of greater than 320 x 200 in 256 colors, I get
an incomplete picture. It is as if the first 1/4 and the third 1/4 of the
picture are shown with the areas in between black. I have disable video
ram shadowing with no success. I am running it on a 386SX motherboard
with Phoenix bios. Oh yeah, the card uses the TSENG chip set. I also
checked that card; it *does* have a MB of DRAM.
Please e-mail with possible solutions.
