Problems Running Dos Programs; Problems During Application Development - Matrox Corona Installation And Hardware Reference

The picture is broken up, with bad horizontal sync; in
other words, it rolls, jitters, or blinks.
The cables connected to the monitor might not be attached
properly or the monitor might not accept Matrox Corona's video
parameters.
Ensure that the synchronization line(s) are properly
connected to your monitor (to identify the sync line(s), refer
to the appropriate monitor configuration in the ' Connecting
to a monitor' section of Chapter 2). If this does not solve the
problem, your monitor might need horizontal setting
adjustments, or it might be defective. Refer to your monitor's
manual.
Ensure that the resolution you specified is valid for your
monitor.

Problems running DOS programs

I cannot run DOS programs in Super VGA modes.
Matrox Corona's on-board VGA is completely compatible with
programs that use standard VGA and VESA modes. It is also
compatible with Super VGA modes. However, if you experience
problems running DOS programs in Super VGA modes, ensure
that the program is compliant with version 1.2 of the VESA
Super VGA standard. Some programs that are written to run
in Super VGA modes are not VESA-compliant, and depend on
the specific chip used for the VGA. They are probably not
compatible with Matrox Corona's VGA extended modes.

Problems during application development

I'm running an application and the system 'hangs' or
produces unwanted results.
Check for an interrupt, memory or register conflict. Sometimes,
an EISA or ISA device might attempt to use the same
interrupts, register or memory space as Matrox Corona, and
this causes a conflict.
