SuperVGA 256 BGI driver
Version 2.4
June 12, 1992
This is the newest version of my SuperVGA 256 BGI driver. I have fixed
several bugs in the previous releases, as well as added several improvements.
o 1024x768x256 color mode is now supported on Tseng 4000,
Chips&Tech, Trident 8900 and Ahead video cards.
o Getimage and putimage will work with bitmaps up to the
size of available memory. (> 64k)
o VESA support has been added.
o Added setvgapalette256 function.
o Floodfill is implemented. (still slow!) (2.0)
o Added new logical operations to putimage (2.25)
XNOR_PUT
NOR_PUT
NAND_PUT
TRANS_COPY_PUT - Treats 0 as transparent (useful for cursors)
o Logical operations for putimage actually work correctly! ;-> (2.3)
o Fixed minor line drawing bug (2.31)
o Support for the S3 card (non-native mode) has been added (2.4)
o Paging has been implemented for SuperVGA cards that support it (2.4)
(Currently only support Tseng4000, C&T, Paradise and Video7;
ATI and Genoa cards do not support paging above 64k)
