Re: TP755CX 800x600 mode




| why the heck are you looking at a 640 x 480 display, why are yuou
| not using the 800 x 600 drivers??? 

Did you read my message?  As I said, I can't figure any way to get
the Linux SVGA driver to work with 800 x 600.  It reports that it
has detected a WD90C24, but that it does not know how to use that
so it is treating it as a WD90C30.   By observation, it is clearly
not 100% compatible.  

For example, one time I run X11 I get clocks:

28.35 28.32 28.73 28.32 28.35 28.32 28.32 28.32
28.35 28.32 28.32 28.32 28.35 28.32 28.32 28.32
31.53

Another time I run it I get:

22.50 28.32 23.77 25.25 22.52 28.32 23.77 25.03
24.34 28.32 23.76 25.03 22.50 28.36 23.77 25.03
25.03

It seems the clocks are programmable, but the WD90C30 driver seems
to assume they are not.  To use the 800x600 resolution I need a
higher dot-clock.  Hence, it seems I need to modify the driver.

| Also why won't the built-in DSP do anything for you?

The DSP drivers are provided for DOS and OS/2.  There must be DSP
code to provide the various functions, and in principle, one ought
to be able to load it with Linux, but the 486-side software is not
there.  The interface between DSP code and 486-side code does not
seem to be one IBM publicizes.
