- Awhile back, I managed to get my paradise card into the supervga modes by
- using the ioctl()'s to read and write the VGA registers, under Xenix.
- Basically, I set the mode under DOS, and read all the registers; under
- Xenix, plugging those same values into the appropriate registers set the
- mode... Kludgey, but it worked.
-
- True device driver level support for the SVGA modes sure would be nice,
- though...
