IDE CD interrupt... if you can get the right version of the hwset utility it shows...

I played around with it. But even if I set /CDIRQ:N and /CD:D and write to EEPROM (I changed the jumper to use EEPROM in the mean time as well) it still uses 2 IRQ's.
I have problems too writing the settings to the EEPROM on GEN3 Aztech cards. For example on my MMSN824 (wich should be exactly your card but without the wavetable).

It just doesnt write the settings.
The star in HWSET shows the base settings not the actual settings.
Reboot the system without loading config.sys and autoexec.bat. Then run HWSET with a wrong command (for example HWSET /d). This will not change the settings (and tell you have used a wrong command) but show the summary with the settings from the card eeprom. (On my card it always sets itself to 0x240 and irq 7 with some weird DMA settings).
I am sure i do something wrong, and i have not figured out what...
I was so desperate that i even read the EEPROM with my EEPROM reader and its empty. (Just the first byte is 01 all others are 00).
And i am also not quite sure if the AZT2316A(your card) acts the same as a ATZ2316-S(MMSN824).
Generation 3 can have 4 different chips. AZT2316 (example MMSN819), ATZ2316-S (example MMSN824), AZT2316A (example MMSN826), AZT2316R (example MMSN845).
I am not sure if each chip needs a specific HWset version.
