I have acquired recently a non working sound blaster 16 CT2230. The card is in perfect aesthetic condition but the card is not detected when inserted in my trusty Pentium MMX 233 (tested with Unisound drivers).
I have thoroughly cleaned it and deoxidized it and not detected any short on the ISA connectors without success. I have also re-flown all of the surface components, including the chips and replaced half of the capacitors. No effect either, the card is simply not detected.
I'm starting to think that it is related to a core component of any sort, but I am not knowledgeable enough to identify it. I simply don't know which component is responsible for the card detection.
Any help here would be more than welcome!!

Isn't that card not actually Plug-And-Play ? AFAIK, Unisound only works with Plug-And-Play cards .

According to this My Sound Blaster 16 CT2230 Review , running Diagnose.exe /s is all you need . The review mentions "semi-PnP", but the description actually implies jumperless soft-config .

Not really, Unisound is perfectly able to detect semi plug and play cards. I have another CT2290 that is perfectly detected. Besides, I gave a shot to diagnose.exe and it did not detect the card. I really suspect something to be wrong with one of the component.

Thanks for the info regarding Unisound . Sorry to read about diagnose not working either .

possible candidates in my opinion:
1) 74LS245 - buffer between ISA data bus and SB data bus;
2) Crystal oscilator, crystal generator
3) main SB chip

Interesting, any way to diagnose that (without an oscilloscope)?
