I hav installed an original MCA XGA card in my Model 55sx.
The installation in POS is ok.
When running a demo coming with the disk: XGAPCDOS - it shows graphics on the XGA's port in 1024x768. So i would say that the card is installed and working.
But i am not able to make the XGA card replace for internal VGA card. On this site it says that it should replace the Internal VGA card, if i only connect the monitor on the XGA card.
On this page on can read: https://ardent-tool.com/video/XGA1.html#W98SE_64K
"If you have an XGA card in a system that has VGA on the system board and a display attached just to the XGA card, the XGA card will function in VGA and high resolution modes."
My goal is to connect my monitor to the XGA card only.
