DELUXE PAINT IIE v2.0 TSENG 4000 PATCH
--------------------------------------
[THIS IS AN UNTESTED PATCH]

If you have IBM Deluxe Paint IIE, and a Tseng ET-4000 card like the new 
STB [or SpeedSTAR VGA], and you can't get it to do any of the SVGA 
modes, here is a patch that works with version 2.0:

We can do it hard, or do it easy.  First of all work on a copy of DP.EXE
please!  If you know how to do this in debug, your a better man than I am,
but I'll give you some ideas.

What you want to search for is the assembly code:

  MOV DX,03CD     (Hex BA CD 03)

  What you want to change is this:

  D0E0    SHL  AL,1
  D0E0    SHL  AL,1
  D0E0    SHL  AL,1
  0AC4    OR   AL,AH
  0C40    OR   AL,40
  BACD03  MOV  DX,03CD

  To this:

  D0E0    SHL  AL,1
  D0E0    SHL  AL,1
  D0E0    SHL  AL,1
  D0E0    SHL  AL,1   (replaces OR   AL,AH)
  0AC4    OR   AL,AH  (replaces OR   AL,40)
  BACD03  MOV  DX,03CD


Now I don't know how to do that with Debug, even if I can find the code &
unassemble it, so I just used a binary file editor (PC Tools) to FIND the
hex BACD03 string, which it said was at relative sector 274, offset 131.  I
went there, and right before it was the following binary code:

   D0 E0 D0 E0 D0 E0 0A C4 0C 40 BA CD 03

  I changed it to:

   D0 E0 D0 E0 D0 E0 D0 E0 0A C4 BA CD 03
                     ^  ^  ^  ^            ^ = changes

Then updated the sector, then used the DPaint setting for the Orchid
Designer Pro.  All modes seem to work except 1024 x 768 x 256, as DPIIE
doesn't yet have that mode for any card.

Incidently, the patch is changing the bank switch code from the Tseng 
3000 to 4000 setings.

Many, many thanks to John Bridges for leaving a message on this, as I
don't know anything about hardware, and Jim Beebe for getting me up to
speed on the dreaded Debug.
