Hi Folks,
We're putting color support into Executor and the folks who are doing
the color additions already have much of color running fine on their
development system. They use the default driver and everything works
fine.
Executor/DOS-color doesn't work on *our* system. We have a Dell
system with an "S3 86C911" based video card. We don't have much
documentation on the card, but we do have a pamphlet called "Video
Software Support Documentation Update" that talks about drivers for
various popular programs (I guess different programs require
different drivers -- yahoo). In the pamphlet is a table called
"Graphics Modes"
Resolutions and Hexadecimal Mode Number Video Mode
Colors
300 x 200; 4 4h, 5h standard
320 x 200; 16 Dh standard
320 x 200; 256 13h standard
640 x 200; 2 6h standard
...
640 x 480; 16 12h standard
640 x 480; 256 69h, 101h extended
...
800 x 600; 256 6Bh, 103h extended
...
1024 x 768; 256 6Dh, 105h extended
All the entries in the table with "extended" in the Video Mode column
have a footnote that says "Requires video drivers".
Nowhere do they appear to claim that they are SVGA compliant, only
VGA compliant with the ability to do these other modes with the
drivers that are supplied on their floppy.
The experimental version of Executor that works on the development
system with the default DJGPP driver pops the monitor into 800 x 600
; 256 mode, which is a resolution or video card can trivially handle
(we run it in 800 x 600 ; 65536 mode under NEXTSTEP all the time).
So I'm guessing that 640 x 400 x 16 colors would work, but higher
ones won't, without a special driver. Would any of the supplied go32
drivers support this video card? It strikes me as really weird that
a LocalBus machine (i.e. a relatively new computer) wouldn't support
SVGA, but I don't really know much about PCs.
