That's sad. I assume MS tried very hard to make Me appear independent from MS-DOS. Me is essentially using MS-DOS as a bootloader/runtime here. Another idea. Check out some beta versions of Me. Perhaps earlier versions still have the dialog still intact. Good luck.

Tested a bunch of cards, only that ET4K worked and gave me a sharp and clean image. Must be a reason why cloudschatze used that et4k too in his T1000RL/HD.

Didn't Creative itself offer DSP upgrades at some point? DSP 1.5 for SB 1.0? Or was it a DSP 2.0 for SB1.5?🤔

...just put an ET4000 card in my Tandy 1000 RL/HD and checking my software catalog against it. Be careful with the ET4000 series, though. It's great for Super VGA titles and demos due to its popularity, but there are compatibility issues with certain EGA/VGA titles. Like Commander Keen (uses EGA). …

For example, I am interested in how DOS/Win 3.x processes and memory work. There are so many companies that made commercial products, that it would be silly of me to think I can do better. Hi!

That sounds really fascinating! 😎 Windows 3.0 had an AT&T driver included, too, I think. Maybe it can be patched. Found a video: https://www.youtube.com/watch?v=yCmU5AXdxmc As you said, 640x400 pels is good enough for Windows. The VGA driver in Windows 2.03 uses it, too. Other versions of the 2.x …

Since DOSBox can install win9x with HDD image, then a DOS image is definitely working, either with a HDD image or floppy image. Actually I've done that with a win9x floppy boot disk image.

^That's fine, but the Game Port is a totally different device, technically. The MPU-401 merely uses two unused pins on the DE-15 connector. MPU-401 is at port 300h/330h, the game port at port 201h.

MPU music works fine on my DOS install using a PnP Vibra16. So you're using a Vibra? 😰 Which model exactly? Do you use the Creative's Plug&Play tools CTCM/CTCU on DOS? If not, maybe the PnP BIOS of your PC does assign the basic stuff as long as DOS is running. Maybe that's why the Windows drivers …

It was not uncommon to have boards with EPROM address and/or data lines "scrambled" with respect to the datasheet, for either data protection or routing convenience. If that's the case here, you will need to rearrange the data in the EPROM to match the card. EPROMs were also used as address …
