From the BIOS:
The only thing I can see is that I have 5 DMA ports, 0 through 4.
The floppy, cd-rw, and hard drives all use DMA port 2 (in Ultra mode).
The only other DMA port I can change is the ECP printer port, which is set at port 3. There's no mention of Sound Blaster compatibility, or even a DMA port for the sound chipset.
From the OS:
I went into these settings:
Device Manager -> Computer -> Properties -> View Resources -> Direct Memory Access.
It shows the Floppy at DMA 2, the ECP printer at DMA 3, and the DMA controller at DMA 4. That would leave 0, and 1, open for business. If indeed the sound chipset has DMA, I can't find mention of anywhere.
The PC is a Trigem Cognac MoBo, with a Pentium III/Celeron processor. The OS is Windows ME, don't ask...
Out of all the older PCs I have, this is the fastest processor wise, but there are no sound cards in sight. (I find the PCs for free, usually...)
I just figured that cutting out the middle men, and possible extraneous variables, would be the best in avoiding issues. If it will run on original hardware (not DOSBox), and run with the original EXEs (not ChocDoom), then I would be sure.
After all, ports like ZDoom/PrBoom/Etc can load non-vanilla dehacked data (frame 966), or even BEX format, and I don't want that.
Honesty though, if ChocoDoom is up to testing Vanilla compat dehacked, I'll be using that on my current PC. Is there an estimate on how close Chocolate Doom is to currently being to a final revision?
