Ryan has persisted in pulling MXGA from the mists of myth-legend.

I have seen a shot of four XGA2 in a 9577 Bermuda, and another image of
four monitors with different segments of the same desktop.

Though you CAN mix XGA and XGA-NI, all XGA implementations MUST be using
the same resolution. So, using IBM drivers for XGA and XGA-NI, you will
be limited to XGA resolutions. Ryan is in deep thought.

Ryan has noticed "ghosting" and uttered a cryptic "With all 4 XGA-2
cards installed it was having problems drawing windows in 64k color.
ghosting in different colors."

This needs further meditation. Ghosting >CAN< be caused by poor cables.
BUT these monitors have been driven HARDER in individual systems. So, it
seems that the cables are fine.

My college career did include broadcast engineering, but I didn't make
the Dean's List... Util we get a clearer understanding of this
"Ghosting", I'm just engaged in Super High Intensity Tinkering...

I counted the contacts on the riser, it appears to be a normular 32-bit
slot with MME and BVE. So... how does this riser support FIVE separate
32-bit MCA adapters?

MAYBE... IBM pulled all five -CD SETUP for the five slots over the MME???

Thinking without alcohol is HARD... Maybe driving four XGA2 over ONE
slot is causing time-of-flight issues. The color information is delayed
due to contention? If the images are correct, but color is shifted...

Dunno. The letter mentions EIGHT instances being supported. MAYBE using separate planar slots prevents interference like Ryan is getting?
