VVESA.TXT April 7, 1993
for VESA Super VGA BIOS Extension VVESA.COM (ver 2.14)


VVESA.COM is a Terminate and Stay Resident (TSR) program. It is
the implementation of the VESA Super VGA BIOS Extension Standard

VVESA is not a driver. It is a program which enables your video
board to be used with VESA compatible software. Consult your
software manual or your software manufacturer's Technical Support
to see if a VESA driver is available for your software.

Install your software for VESA Super VGA. Then run VVESA before
running your VESA compatible software. If you prefer, a batch
file can be written to invoke VVESA and then your software. The
resident portion of VVESA only consumes a small amount of memory.
To run MS Windows 3.1 with VESA 800x600 16-color driver in the
7-bit video mode 6A, VVESA is not required.

To remove VVESA from memory, type: VVESA OFF.

Here is a list of VVESA advanced command line keywords:

OFF Remove the driver from the system memory.

PAN Enable Linear Address
It allows user to pan or scroll within the entire
display memory. Standard VGA will wrap around at the
end of 64K in planar mode. Linear address is disabled
at default.

55rw Force single page read & write mode
The Write Page number is set to Read Page number when a
display mode is initialized. (Note that only display
controller 28800-5 or higher is default to dual page
mode, i.e. the writeable and readable windows can be
programmed independently)

Turns on individual read and write windows which can be
programmed independently for all supported 8, 15 and 24
bit modes including: 100h, 101h, 103h, 105h, 110h, 112h
and 113h.


Does not enable separate read and write windows for
the following 15 and 16 bit modes: 110h, 111h, 113h, 114h,
116h and 117h.

Disables support for 32,768 and 65536 colour modes on
Mach32 products. It will save above 4K of system memory if
your application does not support these high color modes.

If you change the VGA Memory Size setting in the Install
program, you must UNLOAD and then RELOAD the VESA driver.
Failure to do so can cause unpredictable results as the
driver may try and set modes that are no longer supported by
the new setting, or fail to support modes that are now possible.
To unload the driver use the command "vvesa off;" to reload
it, simply use the command "vvesa."

For example, to enable driver to view display memory at
upper 512KB, type:


Then run your VVESA application.

The following VESA modes are supported:


100h 640x400 /256 512KB packed pixel
101h 640x480 /256 512KB packed pixel
102h 800x600 /16 256KB 4-plane planar
103h 800x600 /256 512KB packed pixel
104h 1024X768 /16 512KB 4-plane planar all except V3
105h 1024X768 /256 1MB packed pixel
108h 80x60/16 256KB Text mode
109h 132x25/16 256KB Text mode
10Ah 132x43/16 256KB Text mode
110h 640x480/32768 1MB packed pixel XL, XL24
111h 640x480/65536 1MB packed pixel Mach32
112h 640x480/16.7 M 1MB packed pixel XL24, Mach32
113h 800x600/32768 1MB packed pixel XL24, Mach32
114h 800x600/65536 1MB packed pixel Mach32
116h 1024x768/32768 2MB packed pixel Mach32
117h 1024x768/65536 2MB packed pixel Mach32

Note that some display adapters may not be capable of displaying
all the modes listed above depending on the model, amount of
video memory and how the display adapter is configured. Check
the user's manual of your display adapter for information on how
to configure display adapter and the available modes.



VESATEST.EXE is a utility program to check which modes are
supported on your display adapter, run VESATEST after loading
VVESA. This utility will provide a listing of all VESA modes
available on your card.
