Matrox Corona Installation And Hardware Reference page 63

After installing the MGA Windows NT 4.0 driver for my
Matrox Corona, my system does not reboot at the expected
resolution.
This is a problem that you are likely to encounter if the
resolution settings are incorrect or if the MGA display driver is
not the correct version. These problems can be addressed in the
following ways:
To verify the current resolution settings or to change them,
click on the MGA QuickDesk icon (generally located at the
bottom right of your monitor) and select Display
Properties. The Display Properties dialog box appears.
Select the MGA Settings property page. Set the resolution
to one that is supported by your monitor and click on Apply.
Install the MGA display driver provided with the Matrox
Corona software.
Device attached to the PC failed to start under Windows
NT 4.0
When this occurs, your PC will prompt you to go to the Event
Viewer utility to identify the device that was unable to start.
This could happen due to the following two reasons:
The drivers are not installed correctly. The cause of this error
could be due to too much or insufficient allocation of DMA
memory. To address this problem, uninstall and reinstall the
drivers that failed to start, and specify the correct DMA
setting.
There is a conflict in the BIOS Setup program. This problem
generally occurs when there is a PCI memory mapping error
or when there is a PCI-IRQ routing error. To resolve this
problem, first try to swap boards from one PCI slot to another.
If the problem still persists, upgrade your BIOS.
Not enough environment memory under DOS
This is a message that you might receive when you try to boot
