I have (what I believe is) an ISA Aztech AT-3300 audio/gameport/dialup modem card, taken from a Packard Bell multimedia PC from around 1997. The AZTECH chip in the lower-centre is AZT2320, with OPL.

Does anybody know if this card had any DOS sound drivers released, and where I could find them?

I've found what I -think- is a set of drivers for the card, but they look to be Win 3.1/95 only. http://download.modem-help.co.uk/mfcs-A/Aztech/AT-3300/ Included in the archive is AZTPNP.EXE which may be a DOS program that you can include in your autoexec to initalise the card for Sound Blaster Pro sound in DOS (which would then let you use the card in Win 3.1), but no matter what options I use (it has settings for SB Pro high DMA numbers and IDE support enable/disable), it gives the error 'Can't access C:/AZTPNP.CFG' when I run it. This happens when that file doesn't exist, or exists but is blank. I don't know what format the cfg file is supposed to be, so I can't write it myself without an example.
