PowerVR Tomb Raider Zip Files      Version 2.1
===============================================
This PowerVR version of Tomb Raider has executables for both the 
PCX1 and PCX2 chips. 

Version 2.1, 16 Febuary 1998.

This version only adds support for the new UNIVBE support for AGP and the
latest graphics cards. No other changes have been made since 2.00.

This version will run under Windows 95 in a DOS session PROVIDED you
are running either driver as listed below:

	Apocalypse drivers v4.0.0a or later

	PowerVR v4.0.0 or later

This version now works with Cyrix CPUs, and fixes problems with
800x600 modes on Matrox graphics cards.

Depending on your 2D graphics card it allows you to run at 
various resolutions including 640x480, 800x600 and 1024x768. 
Even if your 2D graphics board has only 2MB, you may still be 
able to run at 1024x768 in Single Buffered mode. Linear MIP 
mapping is supported and on the PCX2 Bilinear filtering is also used.

Unzip the files in the Tomb Raider directory.

===============================================
PowerVR Tomb Raider Installation.  Version 2.1
===============================================
If you have installed an early version of PowerVR Tomb Raider then
you will need to delete the files generated by UNIVBE before you start
this installation. Delete the files UVCONFIG.* and UNIVBE.DRV.

After unzipping the files in the 'C:\TOMBRAID' directory you will find
included two shortcuts that are set-up already to run the PowerVR 
version of Tomb Raider. Just double click the shortcut for your 
PowerVR board.

If any of the following apply to you then you should read over 
the additional install notes below.

- If you use a joystick with Tomb Raider
- If you wish to run in DOS (not in a Windows 95 DOS box), and do not have your
  CD configured in CONFIG.SYS and AUTOEXEC.BAT.
- If you have not yet configured the audio with the Tomb Raider 
  SETUP.EXE program.
- If you have installed the Tomb Raider files to a directory other
  than 'C:\TOMBRAID'

PowerVR Tomb Raider Game Notes.    Version 2.1
===============================================
The following Keys perform the following operations.
F1       - Decreases the screen resolution.
F2       - Increases the screen resolution.
F3       - Displays the current resolution, frames per second and
           whether Single Buffered mode is on.
F4       - Toggles the PowerVR logo. (Full version only).
F8       - Toggles Singled Buffered mode. To switch mode
           the graphics will be reset to the starting resolution
           of 640x480. 
Z        - Zoom the camera in.
X        - Zoom the camera out.
All other keys operate as in the original game.

Single Buffered mode allows the use of high resolutions on 
a 2MB 2D graphics board and it will improve the average frame rate.
However as the 3D image is being sent to the screen at the same time
as the monitor is displaying the image you may be able to see a line across 
the screen from time to time. This is called 'Cut Line' and is normal in
a Single Buffered mode.

Note that the PowerVR version tries to keep as faithful as possible to 
lighting and shading of the original Tomb Raider game. Some areas, 
especially in later levels, are meant to be quite dark.

PowerVR Tomb Raider Install Notes. Version 2.1
===============================================
1. Running under windows.
-------------------------
This version will run under Windows 95 in a DOS session PROVIDED you
are running either driver as listed below:

	Apocalypse drivers v4.0.0a or later

	PowerVR v4.0.0 or later


You will find included two short cuts that are set-up already to run the PowerVR 
version of Tomb Raider. These are named "PowerVR PCX2 Tomb Raider" and
"PowerVR PCX1 Tomb raider". Just double click the short cut for your PowerVR board.


If you have installed TombRaider in a directory other than 'C:\TOMBRAID' then you
can modify the short cuts as follows:

  For example if your TombRaider is installed in your D drive, ie. D:\TOMBRAID
    1. Right Click the "PowerVR PCX2 Tomb Raider" icon if you have PCX2
       (or "PowerVR PCX1 Tomb Raider" if you have PCX1)
    2. Click "Properties"
    3. Click the "Program" tab
    4. Change the "cmd line" line to D:\TOMBRAID\TOMBPCX2.EXE
    5. Change the "Working" line to D:\TOMBRAID
    6. Click "OK"


If you have enabled Auto Insert Notification for your CD-ROM drive in Windows 95:
  When you insert your TombRaider CD, Windows 95 will autorun the TombRaider
  version which you have originally installed with the CD.
  To run TombRaider with this PowerVR patch please do the following when TombRaider
  autoplays: 
    1. In TombRaider Setup menu, choose "Exit".
    2. Double click the short cut for your PowerVR board.


NOTE: If you use "Alt-Enter", "Alt-Tab" or the "Windows" key to switch between
Tomb Raider and Windows 95, your system may become unstable and not be able to
switch back from Windows 95 to Tomb Raider. Please avoid switching between Tomb Raider and
Windows 95 when playing the game.    


2. Running under DOS. 
---------------------
Note that it is important to have your CD installed for operation under DOS.
This will mean you should have entries for a CD driver in CONFIG.SYS and 
that you should be using MSCDEX in AUTOEXEC.BAT.

To run TombRaider:
  Change to your TombRaider directory
    If you have PCX1, run "tombpcx1"
    If you have PCX2, run "tombpcx2"


3. Test the software version first.
-----------------------------------
If the software version, TOMB.EXE, doesn't run then neither 
will the PowerVR version! If you have only downloaded the PowerVR Demo
version and you are having problems, download and check the software 
version operates correctly under DOS and not just in a "DOS Box".

4. Check the audio set-up.
--------------------------
If the audio is not correctly set up, then the movies will not 
play correctly. Please note that the set-up for the sound card may
be different depending on whether windows has been run or not. Check 
the settings with the Tomb Raider SETUP.EXE program.

5. PCX1/PCX2 support.
---------------------
There are two Tomb Raider executables: TOMBPCX1.EXE for earlier 
PowerVR cards with the PCX1 chip (e.g. Apocalypse 3D,or NEC PC3D Engine) 
and TOMBPCX2.EXE for those with PCX2 (e.g. Apocalypse 3Dx or Apocalypse 5D).
Either program will inform the user if the wrong one has been run.

6. Using SciTech UNIVBE.
------------------------
The PowerVR Tomb Raider uses the VESA 2.0 graphics card BIOS standard. 
Most modern cards come with this. However, for cards which do not, 
the game uses SciTech's UNIVBE technology to supply a VESA 2.0 BIOS. 
If the game detects a card which does not supply VESA 2.0, it will run
the UVCONFIG.EXE program which will create a suitable driver.
Although some graphics cards do supply VESA 2.O, they may not provide
very many resolution modes, or they may be causing a problem. You 
can override the card's BIOS and use SciTech's, by using the command 
line option UVBE.

** WARNING! **
WE *STRONGLY* RECOMMEND THAT YOU TURN OFF YOUR MONITOR DURING THE
SCITECH DISPLAY DOCTOR UNIVBE TEST PHASE.


7. Command line options.
------------------------
The command line options should not normally be needed. They 
are case insensitive.
UVBE     - Forces the game to use SciTech's UNIVBE VESA 2.0 driver rather
           than the one supplied with the card (if any). This may also 
           increase the number of resolution modes available to the game.
INFO     - Prints out Program and Driver version numbers
16       - Forces the game to try to run even if the PC has less 
           than 16Mb of memory.
FIX1OSM  - If the display appears to be wrapping around, it could 
           indicate that incorrect information for the display
           has been supplied by the BIOS. This attempts to compute the
           information in a different way. Note that the 'O' in OSM is for
           'Off Screen Memory' and not a number Zero. 
JOY	 - Enables joystick control, however this is currently not compatible with
	   Cyrix CPUs.
Example: 
           C:\TOMBRAID> TOMBPCX2 UVBE JOY

===============================================
PowerVR Tomb Raider Known Issues.  Version 2.1
===============================================
1. Graphics cards with Tseng ET6000 and UVBE option.
The Tseng ET6000 should come with VESA 2.0 support on the board's 
BIOS so you should not have to use the UVBE option. However, if you do, 
on some systems using the UVBE option causes the program to hang. 
An interrupt clash is suspected.

2. Changing 2D Graphics Cards.
If the UVCONFIG.EXE has been used to create a VESA 2.0 driver for your
graphics card, then changing the graphics card may confuse the driver
software. If this appears to be the case, we suggest deleting 
UVCONFIG.DRV and UVCONFIG.DAT in the Tomb Raider directory. This will 
force the game to regenerate driver information.

3. Black Screen on Exit.
Some systems may not return you to a normal DOS prompt. You are still
in DOS - it is just the graphics mode has not been restored. To clear 
the screen type 'mode co80' and hit return.

4. Using saved games between the software and PowerVR versions.
Saved games between the PowerVR and software versions are not compatible.
You will not be able to load the games from the other version.

5. Joystick support does not work on some non-Pentium CPUs.

6. In Windows, do not try to run two copies of Tomb Raider at the same time.

7. Close other PowerVR applications before running TombRaider for optimal
   performance.

8. UNIVBE not running.
You must delete any older files associated with UNIVBE before installing
this version. This version has new UNIVBE support and the files it
generates must be created again.
