ENABLING VIDEO RAM

If you have reserved video space with the EMM386.EXE's /VIDEO switch,
you can use MEMMAX to enable its use as conventional memory. You
should enable video RAM only when that workstation will run
text-based programs (not Windows or Windows programs, for example.)
The workstation uses video RAM to display graphics programs, so you
must disable the use of that area if you'll use graphics.

Without using video memory, your MEM report looks similar to the
following:

Memory Type          Total Bytes (KB)    Available For Programs

Conventional        655,360 (  640KB)       636,704 (  621KB)
Upper               163,840 (  160KB)       159,616 (  155KB)
High                 65,520 (   64KB)        12,400 (   12KB)
Extended          7,340,032 (7,168KB)             0 (    0KB)
Extended via XMS       --------           6,913,024 (6,751KB)

Largest executable program: 636,432 ( 621KB)


At the command line, type MEMMAX +V <Enter> to enable video RAM. Then
run MEM to see the changes in memory configuration:

Memory Type         Total Bytes (KB)     Available For Programs

Conventional        655,360 (  640KB)       735,008 (  717KB)
Upper               163,840 (  160KB)       159,616 (  155KB)
High                 65,520 (   64KB)        12,400 (   12KB)
Extended          7,340,032 (7,168KB)             0 (    0KB)
Extended via XMS       --------           6,913,024 (6,751KB)

Largest executable program: 734,736 (717KB)

Note the significant increase in available conventional memory.
Remember, make sure you run only text-based programs on that system.

DISABLING VIDEO RAM

If you've enabled the use of video RAM, you can disable that use for
running an application in graphics mode. At the  command line, type
MEMMAX -V <Enter>.
