Don't expect too much, the W95 drivers were just warmed over
W3.XX and caused my model 95 to run in DOS mode. Maybe the NT drivers are
better, I don't know as I have never tried them. The W95 drivers do support the
6091-19 as a menu option, which is kind of nice.

The MC1608C/11 is a 2 MB graphics card capable of driving fixed frequency
monitors. It is no surprise that the Cornerstone monitors of the time (1993/4)
are supported, but – pretty surprisingly – also the whole of the 6091
series by IBM.
Selecting the monitor is done via a set of jumpers in the JP1
position of the card (top right corner).

Cornerstone Monitors
CS
Fixed Frequency Color Monitors with ImageAccel Video Controllers.
Monitor - Color 21/76, Color 20/70, Color 19
The Color 21/76, Color 20/70 and Color 19) are fixed frequency color
monitors. These monitors are not compatible with standard VGA video
controllers. Standard VGA video cards require a monitor that operates at
31.5KHz horizontal scan frequency with a 60Hz vertical refresh rate. These
monitors have only been tested using the following ImageAccel video
controllers.
Color 21/76 ImageAccel 1 - MC 1608C/11
Color 20/70 ImageAccel 1 - MC 1608C/11, 1608C/12
Color 19 ImageAccel 1 - MC 1608C/10, 1608C/11, 1608C/12
AdapterId 80A6 ImageAccel Display
Primary or Secondary Video Adapter
Choose primary if ImageAccel is the primary display, otherwise
choose secondary if VGA is the primary display. (Note: If you select the standard of <Primary> for the
video adapter, you’ll see all DOS based messages on the monitor attached to
the ImageAccel. <Secondary> means that you use the ImageAccel only for
HiRes output (which would require another monitor attached permanently to the
BVA).
<"Primary">, Secondary
I/O base address
Choose a 2 byte I/O block with no conflicts
<"2000" (2000-2001)>,
2010 (2010-2011), 4000 (4000-4001), 4010 (4010-4011)
Memory base segment address
Choose a 8K memory block with no conflicts.

The settings are not critical as long as they don’t conflict
with other settings.
