[Possible Bug?] Blank CGA

[gen_angry]

Hello, I am trying to create an AMI XT with an 8088 7.16Mhz CPU + CGA graphics. Using v12 stable release.

When I try to boot up, all text is blank (and the cursor moves like it is doing something). However, using an ET4000 (for testing) works and all text is displayed.

PCem.cfg is attached.

This is what I get using a CGA (the cursor moves around rapidly)


This is what I get with the ET4000


Apologies if this isn't a bug, I tried searching the forum for something about this and couldn't find anything.

Thank you

You are missing the MDA video adapter font (mda.rom) hence the CGA adapter isn't working properly. This also effects the Hercules, MDA, and other CGA-based video adapters (like Plantronics ColorPlus) though it doesn't effect VGA and EGA adapters.

Try to put 'mda.rom' (or if you didn't have it, try to search online for it) in the "roms" folder and it should work again.

One minor correction: The Wyse 700 gets its characters from wy700.rom, not mda.rom.

I forgot about that actually. Thank you for the correction. Will be editing my post shortly.

That was it, thank you.



Feature suggestion: If this rom is missing, have it display a note?

It would be useful to have all the rom files required for your current configuration listed in a new tab or maybe a completely new window that lists all the files that PCem looks or might look for and their status (with checksums even to make sure it's the right file).
