SPEED is a small resident program that replaces the BIOS coding for a number
of Video I/O calls. The BIOS coding contains a great deal of overhead which
slows down the CRT display. By doing away with this overhead, SPEED-CRT
significantly increases the display speed of any applications program that
uses the BIOS. Programs that write directly to the screen will not be
An EGA card is required for SPEED to be loaded. It will function in any of
the text modes, including monochrome. It will automatically deactivate itself
if a graphics mode is invoked. Similarly, once a text mode is re-invoked, the
coding will be activated.
SYNTAX: Speed [argument]
When installing SPEED for the first time, as in an AUTOEXEC.BAT, no arguments
are accepted. After that, the resident coding can be toggled on/off from the
DOS command line, or a batch file, using a hyphen (minus sign) as the
argument. While I haven't found a situation where there's a problem with
SPEED, the flexibility to toggle it off is worth the extra code.
SPEED can be installed at any point in your line-up of resident programs.
However, maximum display speed is realized if it is installed last.
