Can a crappy Avance Logic ISA sound card "draw too much current" and the PSU can't handle it ? Because that's the only actual thing I did... I just added an ISA sound card to "level this PC up and get rid of that noisy PC speaker once for all"... but I can't think it's the cause... after all why …

You can tell from this wikichip page which 5x86 chips had what. Click on each one in the list, and it will tell you how much and what kind of L1 cache the chip had https://en.wikichip.org/wiki/amd/am5x86

Not sure how he would solder in an AA battery. Keep in mind CMOS voltage ranges from 3-4VDC with 3 AAs (GREAT if you have 1.2v rechargable AAs) under load, it will be fine. Not sure if the Dallas RTCs have CMOS power in to bypass the battery, probably don't. There probably is a way around it, but …

BIOS should report the FPU in some manner. You can try a few benching tools from Phil's dos benching kit, I think the one that uses AT 286/287 scores should work for that, forgot the name tho.

My guess is if it says MT-32 on it, it will be an MT-32 or compatible?

Wow, actually that fixed it. And I did have that exact line in the previous MS-DOS 6.22 install. HOWEVER, it was before loading EMM386, not after, maybe that changes things? Either way here is my mem now, again in two files, one after a fresh boot, one with MT32 EMU loaded. Fresh: Modules using …

Yea, pick it up. MT-32s cost an arm and a leg. I honestly stuck with the AWE32 as I don't have 300 dollars to get everything I would need for an MT32 + audio + OPL setup.

The search term is x86 ASM. That's what people used to use to crack games, and that's what a lot of games were programmed in. That, or C, which is slightly easier, but with SLIGHT overhead.

For the DALLAS chips, you can find datasheets online, but those are tricky SOBs. I specifically bought a board without one for the sole reason of NOT having to deal with them. If you want to do it the right way, pick up a 50 cent drop in replacement RTC chip, unsolder the chip (Cheap soldering iron …

Uh, conventional memory makes for a long story. "MEM /C /P" at the DOS command prompt will give you an overview of the situation. You're forgetting to load EMM386.EXE after HIMEM.SYS, and "DOS=HIGH" comes after. Also to optimize you probably should trim some of the AWE32 stuff down to the …

ZZT is your best bet in my opinion.
