SMALL FONTS AND ICONS FOR WARP SVGA DISPLAY DRIVERS
---------------------------------------------------
Version III
-----------
** Please take time to read the disclaimer situated **
** at the bottom of this file. **
Introduction
------------
The SVGA display drivers from IBM have an annoying habit of using
large icons and fonts at resolutions above and including 1024x768.
The program contained within this archive was written to address
this problem by making alterations to the display drivers to give
small fonts and icons.
The program has been used with success on the following versions of
Warp, and the following display drivers:
Warp version Graphics adapter Driver name
Warp II beta V7 SPEA Mirage
(S3 32bit drivers ... IBMS332.DLL)
Diamond Stealth 64
(IBM/S3 864 ... IBMS332.DLL)
Warp GA V7 SPEA Mirage (S3 68C801, ... IBMS332.DLL)
ATI Mach 32 (ATI Mach 32 ... ???.DLL)
Cirrus Logic 5428 VLB
(Cirrus Logic 5426, ... CIRRUS.DLL)
Cirrus Logic 5426 (CIRRUS.DLL)
Orchid Farenheight 1280 Plus VLB
(IBMS332.DLL)
Diamond SpeedStar Pro VLB
(CL5426 CIRRUS.DLL)
Diamond Stealth 64 DRAM (2Mb)
(1.03 drivers from hobbes.nmsu.edu)
(IBMS332.DLL)
ET4000W32i (TLIW32PM.DLL)
Procedure
---------
1. Install the high resolution drivers using Selective Install if you
haven't already done so.
2. Take a backup of the file "\os2\dll\ibms332.dll" and call it something
like "\os2\dll\old-ibms332.dll".
eg.
cd \os2\dll
copy ibms332.dll old-ibms332.dll
If you are using a non-S3 adapter, then replace the "ibms332.dll"
with the name of the display driver DLL. This might be
"ibmsvga.dll", "atim32.dll", or "cirrus.dll", or something like
that! :-)
3. Run the program "fixdisp.exe" included in this archive. The
program takes two parameters:
i. The name of the original (unpatched) display driver DLL
ii. The name of the patched display driver DLL that the program
is to save.
eg.
fixdisp \os2\dll\old-ibms332.dll \os2\dll\new-ibms332.dll
The program defaults to the above two parameters if none are
specified. As of version III, fixdisp will not attempt the
1280x1024 font patch, since although I believe it is probably
correct, I have no way of testing it. To enable this patch,
specfify a third command line parameter of "/T" (without the
quotation marks).
4. The program will (hopefully) run and display four messages relating
to patching fonts, icons, and DPI.
If the program was unable to make all the necessary alterations
then it will let you know. You should NOT try to use the patched
DLL that is saved; you may have tried to patch the wrong DLL. Try
using a different (correct) DLL name, or try to make alterations to
the program's source code so that it works.
5. Shutdown your machine, and reboot. When the white block appears at
the top-left of the screen, hit ALT+F1. This should bring up a
menu screen, on which you should hit "C" to boot to a command
prompt.
Now copy the patched DLL on top of "\os2\dll\ibms332.dll".
eg.
cd \os2\dll
copy new-ibms332.dll ibms332.dll
Do not remove old-ibms332.dll since you may need it if the patch
has not worked.
Reboot (type "exit").
6. You should now have small fonts and icons at resolutions of
1024x768 and above.
If you experience problems, such as impossibly wide icons, black
icons or strange fonts, then repeat step 6, copying old-ibms332.dll
on top of ibms332.dll to undo the effects of the patch.
Finally,
If you have tried the program with non-S3 graphics adapters and it
has worked, then please let me know so that I can build a list of
the adapters that it works for. Please include the Adapter name,
DLL name, and name of the Drivers as they appear in Selective
Install. Thanks.
Please note that this program does not even attempt to address any
problems you might currently have regarding refresh rates or the
ability to achieve resolutions of 1024x768 or above.
The source code
---------------
The source code for fixdisp.exe is located in the source directory
contained within this archive. It compiles with Borland C++ for OS/2,
IBM CSet++ and also gcc/emx apparently. If you make alterations to
it, and yoy think others may find them useful, then please send me
a copy!

Daniel J Neades (djn@arac.demon.co.uk), for the information about which
bits of the display drivers need twiddling.
John J. Lehett, for details about compiling fixdisp.cpp with emx/gcc
and for reporting success with the ATI Mach 32.

DISCLAIMER (very important)
----------------------------
The authors accept absolutely NO responsiblity for any adverse
consequences of the use or misuse of this program. IBM will probably
not provide any form of support for modified display drivers.
Modifying display drivers is a messy business. If you are not 100%
confident in your display driver twiddling abilities then DO NOT USE
THIS PROGRAM. You have been warned.
