1.0     Supported VESA modes

The VESA modes supported by your mach64 card are dependent upon the 
amount of video memory and the monitor type selected in the ADVANCED or 
QUICK SETUP.

To determine the modes supported by your current configuration you must 
install the mach64 utilities, then run VESATEST from the mach64 directory.  

1) Run INSTALL and select "Utilities Installation" from the Main Menu.  
2) Follow the screen instructions to completion.
3) When INSTALL finishes copying all necessary files, press <escape> to 
   exit install. 
4) Change directory to the mach64 (default) directory and type "VESATEST".
5) All the modes currently supported will be displayed.

2.0     mach64 VESA TSR 

If you experience any problems with applications that use VESA modes,  
install and run the ATI mach64 Terminate and Stay Resident (TSR) VESA  
program M64VBE.COM. 

The default settings for M64VBE.COM are:

- dual read and write windows enabled
- 320 modes enabled
- VGA Wonder memory paging disabled
- VGA CRT parameters enabled

To install M64VBE.COM: (from a DOS prompt)

   - Insert Disk # 1 in the floppy drive. Type:
     A: <enter> (For drive b, substitute B: for A:) 
     CD\ <enter>
   - Start the installation program by typing:
     INSTALL <enter>
   - Select "Utilities Installation" from the Main Menu.  
   - Follow the screen instructions to completion.
   - When INSTALL finishes copying all necessary files, press <escape> 
     to exit install. 
   - Change directory to the c:\mach64 (default) and type:  
     M64VBE <enter> to load the program.
   - Start your VESA application


To un-install the mach64 VESA TSR Change directory to the c:\mach64 
(default) and type M64VBE U <enter>.

Note: If you experience any problems unloading the TSR please consult 
your DOS documentation for TSR un-install limitations.

3.0     M64VBE Advanced Switches


If your VESA application continues to experience display problems after 
loading M64VBE.COM, you should consult the application's documentation 
for specific requirements.  If the documentation indicates that it 
requires VGA Wonder paging, single read and write windows or accelerator 
CRT parameter you must use the Advanced M64VBE switches listed below.

Syntax:  M64VBE sw1 sw2... (where sw# represent a valid M64VBE switch)

M64VBE SWITCHES:

    s   - Enable single window implementation. This single window will be
	  readable as well as writable.
    d   - Enable dual read and write windows implementation.
    3   - Enable 320x200 & 320x240 modes in 8bpp, 15bpp, 16bpp and 24bpp.   
	  VESA mode number 202h, 10dh, 10eh, 10fh are for 320x200 8bpp, 
	  15bpp, 16bpp and 24bpp respectively. Similarly, VESA mode number 
	  212h, 213h, 214h and 215h are for 320x240.
   -3   - Disable 320x200 & 320x240 modes.
   vw   - Enable VGAWonder memory paging. Mach64 uses a different paging
	  scheme from VGAWonder paging scheme. This option will make 
	  Mach64 backward compatible to the VGAWonder paging scheme.
  -vw   - Disable VGAWonder paging.
  vga   - Use standard VGA CRT parameters.
  acc   - Use accelerator CRT parameters.   
    u   - Unload or remove M64VBE from memory.

4.0     Known Problems

MOUSE CURSOR PROBLEMS
If you are experiencing mouse pointer trails or any problem associated 
with a pointing device, the VESA application may require a single read 
and write window. To correct this problem, use M64VBE with the single 
window implementation enabled.

Affected applications include:  
	OPERATION CRUSADER by AVALON HILL
	WORD PERFECT TUTORIAL by LEARNKEY, INC.

syntax: M64VBE S VGA


1/4 OF THE IMAGE VISIBLE
If the VESA application only displays in the upper 1/4 of the screen the 
application may be assuming that the mach64 is a VGA Wonder compatible 
card.  To correct this problem use M64VBE with the VGAWonder memory paging 
enabled and VGA CRT parameters.

Affected applications include: 
	AIR WARRIOR by KESMAI
	THE GRANDEST FLEET by QUANTUM QUALITY PRODUCTIONS
	FXDRAW by ROBOCFG

syntax: M64VBE VW VGA


BLACK SCREENS OR SYSTEM HANGS
If starting the VESA application causes a black display or locks the 
system, the application may not be compatible with Accelerated CRT 
parameters. To correct this problem use M64VBE with the standard VGA CRT 
parameters enabled.

Affected applications include:  
	RISE OF THE ROBOTS by TIME WARNER INTER.
	HARDBALL IV by ACCOLADE INC.
	EIGHT BALL DELUXE PINBALL by AMTEX
	DESQVIEW/X by QUARTERDECK OFFICE SYSTEMS
	OCEANS BELOW by SOFTWARE TOOLWORKS

syntax: M64VBE VGA
