I'm fiddling with a PCI soundcard in a 486 DX4/100 system. The options in the AMI BIOS are very limited for IRQ settings. I have 4 settings that go like:

1st available IRQ 10
2nd available IRQ 11

and so on. The settings in autoexec.bat seem to work. Soundcard is initialised (and gets IRQ 10, I can see that in sbinit.ini). The moment it does I can hear something coming alive out of the speakers (soft noise). But everything I do after that results in a lockup of the system. Doesn't matter if it uses sound or not. Just simple typing edit will lock it up.

It is a Creative CT4810. I have several of those. I tried them all and got the lock up every single time. So the card is ok. The solution must be in the bios. Hope someone solved this allready.

This is the output from the autoexec.bat file. When I change the bios settings it changes too. So it finds the IRQ.
