Got myself an interesting one:
The attachment mediagx.webp is no longer available
A Cyrix MediaGX board with Cx5530 chipset, but which one... it doesn't match with any of the ones on TheRetroWeb. And then there's this:
The attachment general_softwar.webp is no longer available
General Software Inc. Embedded BIOS 4.3 instead of the usual AMI/Award/Phoenix. Inside the BIOS setup, there's an 'About' tab that says this is an evaluation board, so possibly specific to General Software.
Unfortunately only a very limited number of EBIOS modules were compiled for the image on it, so only drives and ROM shadow config can be set, nothing about the integrated devices like SB16.
If I can ever find sources to build my own EBIOS I could have a lot of fun with this. But I haven't been able to so for. So...
After backing up the EEPROM, I flashed it with ECS P5GX-M BIOS, given that the boards appear functionally identical and yes, it works.
Audio is interesting, a very metallic-sounding FM synth, but pretty decent SB16 otherwise, with absolutely no software needed to work in DOS - just set resources in BIOS and point games to it. Haven't been able to test compatibility a lot yet, Civilization failed to produce any audio (old AdLib game, maybe the audio is only listening to 0x220 not 0x388...), Ascendancy failed to run due to failed memory check (60MB free was too much for it 😉 ) and OMF also failed to run without error message. Will try a bit more (including MIDI) tomorrow...
