actually its the opposite. With WDM drivers (aka sbemul.sys) , there is emulated mpu401 device which is redirected to whatever you select in the midi mapper, and there is absolutely no adlib/fm emulation (sbemul only emulates the opl timers but generates no sound). Since you mention adlib emulation …

Note that himem.sys needs "unreal" mode to work, and dosbox can boot it just fine. In fact, if I remember from some discussions on these forums, when using himem.sys dos itself spends most of the time running in unreal mode, with all descriptors having 4GB limit, since neither himem.sys nor the …

Remember it's going to be a PCI Sound Blaster 16, which already doesn't have stellar compatibility with DOS games, and no OPL chip, so it's probably not worth the effort. At least you don't have to worry about passing through the "classic" ISA SB16 IO ranges (22xh, DMA channels, IRQ) because, at …

Still this is not related to SSDs, it is all about SATA controller. It would be the same for a rotating disk plugged in to a SATA port. …

My first idea was to write a "small" TSR program that just wrapped the DOS IO API functions.

This makes installing/running Win98 impossible if you have a Ryzen CPU. Intel still works fine though. What do you mean?

Note that this is supposed to work. When you use the normal WDM driver, sbemul.sys is supposed to utilize whatever you select on the MIDI mapper.

Did you try MPEG-1 ? I keep thinking that for a 98-era machine Cinepak is like a bad joke. If it has enough horsepower to decode it, the MPEG codecs are on another league entirely. And 98 should definitely come with MPEG-1. SE came with MPEG4... (part-2 aka asf aka divx, not h264).
