The card is a combo modem sound card in particular Aztech Labs I38-MMSN841 Sound Card Modem 16 bit. I switched it from EEPROM to software and any detection and installation of drivers through windows either don't function or it crashes immediately with a general protection fault. I only have one PC with 16-bit ISA to test it in. I recapped the board and now it doesn't crash when installing drivers most of the time.

I've bought a new voltage regulator and will install it to rule out a hardware fault.

Before anyone asks I did make sure all the resources it was trying to use were free. I also use contact cleaner on the slot and edge connector.

All the drivers on this site seem to be for other models if anyone can help I would appreciate it.

What happens in pure DOS and run Unisound?

Any FM (OPL) music in any particular game?
Digital sound?

You know I haven't even thought of checking to see how that works. I'm at work right now but when I get home I'll check it. I don't know how it'll react because I know I didn't install DOS drivers myself.

I won't be home until midnight so I probably won't be able to report back until sometime tomorrow. It's currently 5pm where I am now.

If push comes to shove:

Use Unisound to initialize and configure the hardware before windows starts.

Force windows to install the generic soundblaster 16 audio driver.

Force windows to install the 'Standard [speed] modem on [COM port]' driver.

Aztech DID provide windows drivers, but that's not explicitly necessary. At the end of the day, it's a clone of a soundblaster 16, with an integrated modem.

The integrated modem uses a Rockwell chipset, which means this is a real UART based modem. As long as it gets an IRQ and an IO address (and windows sees it as a com port), the 'generic modem' dtiver will work fine

Where can I find unisound. I'm not very experienced with older computers. I mean I've gotten several working but this is the first time I've ran into a problem I couldn't solve on my own.

I tend to do everything inside of Windows because I'm not experienced in doing things in pure DOS.

Thanks. I do remember when I set it up in windows it did install generic soundblaster clone drivers. Once it was done it had resource conflicts.

I fixed that and it had me restart then it said the hardware was not detected or the drivers weren't working. I update the drivers and it said the better driver was the sound galaxy Washington driver. I let it install it and got a blue screen of death.

Upon reboot it hanged on normal startup. Removing the drivers in safe mode let me back but of course the card still didn't work.

Just back on topic-- This appears to be your card.

https://www.dosdays.co.uk/topics/Manufacturer … diotel_2000.php

It was commonly found inside Packard Bell computers. For the audio side, the Washington 16 drivers will probably work.

For the modem side-- again, as long as windows sees a COM port, just slap "Standard Modem" on the com port windows detects.
