I had a quick look through all of this, and there is definitely something strange going on. The DUMP report shows what we already knew: the PnP BIOS didn't find or report any cards. So, the fact remains that even the BIOS designed for those boards cannot consistently find any PnP ISA devices. When …

I thought I'd give an update on PicoGUS 2.0: boards are now in production at JLCPCB. I hope to get them by next week! Also, I have quotes out with some sheet metal bracket fabricators for a metal bracket for PicoGUS 2.0. That will raise the selling cost of PicoGUS 2.0 from $40 to $45, but I think a …

Speaking of which, the "TYPE" variable in SET - it's defaulted to 4 - can this be set to say TYPE 6? and is Orpheus II only SB Pro compatible and not SB16 compatible? The CS4237 provides compatibility with the second-generation (single OPL3) Sound Blaster Pro, so T4 is correct. You could set it to …

Figured it out, was entirely user error. I had set my oplirq to 7 in the orphinit ini. It was leftover from when I was testing/trying to resolve a conflict with a different device. The FM synth can have an IRQ assigned, but there is basically no reason to do so, as virtually no software ever made …

The Audiotrix Pro used a Crystal CS4231, so I suspect the drivers aren't doing anything TOO funny for the newer chip on the Orpheus cards. That's the key detail: the Sierra/Mediatrix driver works , but some of it is kind of sloppy or questionable, and doesn't support all of the less common …

I know someone who just got one of these [1] for 329 CAN$ + taxes and shipping . If your wife's needs are relatively modest, you can spend a little more time looking and find Intel-based machines for less. Just as an extra development machine for these purposes, that's likely the approach I will …

640K!enough here are the two files. I had a look at the two files, and it is indeed a peculiar problem. In the first case, it seems to behave perfectly. Then, with that adaptor installed on the secondary channel , the Crystal device doesn't enumerate or respond at all to any type of initialisation …

Can anybody explain the situation with WSS and the CS-4237? It sounds like certain games (ie. Sierra 16-bit and 32-bit?) have problems but there exists patches (thanks 640k!enough). How well any software will work with the CS4237 depends largely on the title's detection routines. If they …

Whats' the best way to send these two text files to you?

I have CF-IDE adapter installed yes - the issue is with the CF card that is used. There are CF-SD cards that allows you to slot microSD card into a CF card - an adapter if you will. It seems that Orpheus has trouble initialising if you use these CF-SD cards instead of an actual CF card itself. If …

Just got the boards in, plopped on a Geforce4 Ti4200 AGP card, and got video! 🎉 It's always nice when things work as intended. Did that require any additional bring-up code, or was it all configured at the hardware level, and worked without BIOS-level changes? Any idea what the compatibility list …

I'm wondering if adding some kind of "detune" mode would make the OPL3 sound richer? It might, but, as Tiido said, it would not be an easy thing to do, and for questionable advantage. Here, you'd have to insert that middleman before the CS4237, which already handles almost all of the bus …

YMF718 chip seems to care to some extent about what is in the EEPROM and will not function right when there's garbage in it, although it will start up without the EEPROM. Interestingly, the CS4237 exhibits similar behaviour. Sufficiently corrupt or incorrect EEPROM content can cause it to enter a " …
