Video Display Problems - Matrox Corona Installation And Hardware Reference

Not enough memory to allocate buffer under Windows
NT 4.0
This is the message that you will receive if you try to allocate
a grab buffer that is greater than the amount of DMA memory
specified during software installation. This problem can be
addressed by increasing the amount of DMA memory on your
system. Allocate DMA memory as follows:
yuxp„ˆÂy†pyg
Replace x with the appropriate amount of the DMA memory in
Kbytes.
For example, if Matrox Meteor-II and Matrox Genesis boards
require 2 and 4 Mbytes of DMA memory, you would request
6144 Kbytes.
Linking or compiling error under DOS
To avoid running into this problem, install MIL-Lite (versions
5.0 or greater) after installing Watcom Version 11.

Video display problems

My monitor is blank (or it has shades or spots of gray and
white).
Check that the system is plugged in and make sure your
computer and monitor are turned on.
Recheck your connections at both ends of the video cable.
Ensure that Matrox Corona is sitting evenly and is fully
inserted into its slot. To do this, press the board down firmly.
Check that the brightness and contrast controls are set
correctly.
Set the monitor's switches (if any) to 75 ohms for the video
(RGB) inputs, and set the synchronization to ' external' (and
to high-impedance if this option is available). If there is a
Digital/Analog switch on your monitor, set it to Analog.
