1. Overview
|
|
|
|
S3 Speed Up is a TSR program, which can speed up most banked VESA
modes (no text or 4 bits/pixel modes) and VGA mode 13h (320x200x256)
on S3 graphics cards.
|
|
|
|
S3 Speed Up requires S3 VBE/Core 2.0 (version 3.10 or higher).
|
|
|
|
2. Installation
|
|
|
|
You must install S3 VBE/Core 2.0 (version 3.10 or higher) in memory
before installing S3 Speed Up.
|
|
|
|
Simply type "S3SPDUP /LOAD" to install S3 Speed Up in memory.
|
|
|
|
Type "S3SPDUP VESA+" to install S3 Speed Up in memory and activate
banked VESA modes speed up.
|
|
|
|
For savety reasons S3 Speed Up is disabled at Windows(tm) start up and
shut down. If you want to use S3 Speed Up under Windows(tm), you must
activate S3 Speed Up in each DOS box.
|
|
|
|
"S3SPDUP /?" shows a help screen.

|
3. Speed up
|
|
|
|
S3 Speed Up can speed up most banked VESA modes (no text or
4 bits/pixel modes) and VGA mode 13h (320x200x256).
|
|
|
|
To speed up these modes S3 Speed Up must temporary change the
PCI base address, which may cause problems!
|
|
|
|
E.g. programs using the S3d(tm) engine (native S3 ViRGE programs)
may or may not run, if banked VESA modes speed up is enabled.
|
|
|
|
The speed up of VGA mode 13h is not 'Mode X' compatible. This means
that some programs (e.g. DOOM) will not work when the VGA mode 13h
speed up is enabled.
|
|
|
|
Only use VGA mode 13h speed up, if you are familiar with 'Mode X'!
|
|
|
|
Programs using VESA VBE/Core 2.0 linear frame buffer modes
(e.g. QUAKE) will not profit from banked VESA modes speed up.
