-
- VVESA.COM is a Terminate and Stay Resident (TSR) program. It is
- the implementation of the VESA Super VGA BIOS Extension Standard
- #VS900602.
-
- 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 Window 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)
-
- For example, to enable driver to view display memory at
- upper 512KB, type:
-
- VVESA PAN <enter>
-
- Then run your VVESA application.
-
-
- The following VESA modes are supported:
-
- MODE RESOLUTION MEMORY MEMORY
- NUMBER /COLORS REQUIRED MODEL
-
- 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
- 105h 1024X768 /256 1MB packed pixel
-
- Note that some display adapters may not be capable of displaying
- all the modes listed above. Check the user's manual of your
- display adapter for the available modes.
