I feel like I'm so close to this working. It's been a whole thing to get this far, read through a lot of threads, but I've learned a lot about DOS.
I got an HP thinclient T5740, trying to use it as a DOS gaming PC with FREEDOS. I've disabled in the BIOS the networking, serial and parallel stuff, and everything that isn't the USB controller because I read that that might eat up IRQs.
I've got the YMFDOS folder installed with SETUPDS and DSDMA that Philscomputerlab provides. Without running DSDMA I can get music working in freedoom and the 16 bit sound test in SETUPDS works. The 8 bit Sound Blaster test in SETUPDS is grayed out, which apparently is what DSDMA is supposed to fix.
I limited the visible RAM to 512MB using the HIMEMX switch /MAX=524288 and DSDMA seems to run correctly instead of just crashing the PC like it originally did without the RAM limit.
After running DSDMA however any time I run a program that uses the card, like launching a game or running SETUPDS again, it crashes the PC. The SETUPDS screen comes up, but immediately freezes with the error "codec might not be connected".
I haven't had much luck searching for that error message, and I think I'm out of ideas. I saw somebody on ebay a while back selling this model thinclient with the same card with a DOS installation, so I bet it's possible to get it to work, I'm just out of my depth. Any ideas would be great, or even just a RTFM with a link.
Thanks!
edit:
the rest of the error message mentions EMM386, so the issue could be with how I've got the memory set up. The FDCONFIG.sys is the default #2 option in FREEDOS with the memory limit switch.
Edit2:
Got it to work in freedos. Have to limit the ram HIMEMX sees to only 64Mb with /MAX=65536. It's possible it'll work with higher than that, but it won't work with 512Mb, and 64Mb is the max for DOS anyway
