Supports G550. I don't have a Matrox, so I didn't download and test it.

My previous description naturally only works when you have the MGA Drivers installed.
If you make a new installation with these drivers, make shure the following lines are in the config.sys
SET VIDEO_DEVICES=VIO_MGA
SET DISPLAYTYPE=VGA
SET MGA=C:MGAOS2
SET VIO_MGA=DEVICE(BVHVGA,BMGAX64)
DEVINFO=SCR,VGA,C:OS2BOOTVIOTBL.DCP
DEVICE=C:MGAOS2KMGAX64.SYS
Adapt them to your drives etc.
