From: "da Silva, Joe" 

Hi folks,



I've been looking around for an ET6000 data sheet, but

without success. I wonder if anyone here has this or at

least, suitable programming information? The RBIL Ver61

has very little information (more on the ET4000), BTW.



After much seeking, I located the released DOS utilities

for the Tseng ET6000. What I need is the ability to set

refresh rate and horizontal position for graphics modes,

to suit my monitor. However the DOS utility only seems to

implement Int 10h, AH=12h, BL=F1h (Get/Set Screen Refresh)

which unfortunately only supports four refresh rates for

each resolution, so at 800x600 in particular, the result

is unsatisfactory with my monitor.



There seems to be much more information available on the

ET4000, but this seems only partly compatible with the

ET6000, particularly regarding the clock settings. There

are too many registers that change between known graphics

modes for me to decipher what's what, so it seems I can't

proceed further unless I can find a data sheet. Ultimately

I want to make a little customized TSR to hook Int 10h,

which will set the clock and other registers as needed.



Joe.
