system. Use the MILConfig utility to do so. Alternatively,
uninstall and reinstall MIL and specify the appropriate amount
of DMA memory.

Grabbing problems

Opto-isolated trigger pulse is not connected
When using the opto-isolated trigger, both OPTOTRIG- and
OPTOTRIG+ signals must be connected. OPTOTRIG- is
usually connected to the ground of the trigger source.
IRQ conflicts
In general, AGP and PCI devices use the same interrupt
signals; therefore, an AGP device can share an interrupt line
(IRQ) with a PCI device. However, sometimes this might not be
possible. The types of difficulties that you might run into are
as follows:
BIOS driven IRQ conflict under Windows NT 4.0
In the event that your Matrox imaging board(s) cannot share
an IRQ line, allocate a different IRQ to each device in the IRQ
Configuration Setup section of the BIOS Setup Program
(accessible on bootup).
IRQ conflict under Windows 2000
To resolve this problem, either re-assign a different IRQ value
to the AGP slot or change the resource settings in the
Windows' Device Manager property page. This page can be
accessed using the System utility in the Control Panel.
Note that AGP and PCI devices cannot share interrupt lines
with EISA or ISA devices.

Video display problems

My monitor is blank (or it has shades or spots of gray and
white).
Make sure your computer and monitor are plugged in and
turned on.
Recheck your connections at both ends of the video cable.
