[comp.sys.ibm.pc.misc] ET4000 Tsjeng, Optima MEGA Driver Req

coert@dnlunx.pttrnl.nl (Coert J. Vonk) (10/04/90)

Dear Neater:

Yes, I was pretty overwhelmed by the prospective of the Tsjeng ET400 chip.  It
promised me a 1024x768 resolution and 256 colors at the same time.
Unfortunately, the Optima MEGA card which uses this chip did not include a
driver for MsWindows3.  Hence it would not run MsWindows3 in 386 enhanced mode,
or 286 protected mode.

Is one of you so lucky to use any of such drivers.  If so, please contact me.

cica.cica.indiana.edu has a collection of Windows 3 drivers, including
one for the ET4000 chip. It's in the /pub/pc/win3/video directory and is
called tseng4k.zip. According to a friend, who has an Optima ET4000 card,
it does work in all three modes.

If these are the same drivers from Tseng labs dated 8-14-90, they do not work
in 1024x768 enhanced mode ! All other combinations work however.

No, these are the drivers from 05-29-90, which are called 

              PRELIMINARY
   TSENG ET4000 DRIVER INSTALLATION
       FOR MICROSOFT WINDOWS 3.0

in the WIN30.DOC file contained in the TSENG4K.ZIP archive available on
cica.cica.indiana.edu. The archive contains the following files:

 VDDTLI4  386    15131 05/18/90 17:30    39996

According to my friend who has the Tseng MEGA VGA 1024 card with the ET4000
chip, these drivers work in all three modes on his 386 machine.  My own
Optima 1024 uses the Tseng ET3000 chip and is of course not supported
by these drivers. Fortunately, by mixing driver parts from Eizo with
driver parts from Orchid (both available on cica.cica.indiana.edu) I
finally got a working 256 color driver, which runs in all three modes
on *my* card.

I had these drivers before upgrading to the 8-14-90 versions. The 1024x768
driver does not work in enhanced mode in either version. If you call Tseng
labs (which I did) they will confirm this bug and the fact that they are
working on a solution. Note that both versions are beta drivers.

I just asked my friend who has the Tseng MEGA VGA 1024, to whom I had
given the TSENG4K archive. According to him, all drivers from this archive
work in all three Windows 3 modes (real, std, enhanced), on his
card.
