I tried to use FreeBSD-ISA_PnP_June8.tar.gz (with a 2.2.1 kernel) to change the IRQ on my Creative SB16 PnP from 5 to 10. I eventually got the new code to compile, and it recognized my SB16 and seemed to go through the motions of configuring it, but the card simply doesn't work right (kept getting "DMA timed out - IRQ/DRQ config error?" kernel errors). I can change the IRQ for the card in DOS (it works fine at IRQ10 under DOS and Windows) -- but in order to do so, I have to select one of the card's non-default configurations first (configuration 0 only allows IRQ5). Is it possible that this might be why the FreeBSD code couldn't change the IRQ? See below for the output of "pnpinfo" on my system. BTW, I had problems getting the code to compile properly at first, apparently because of confusion between the "pnp.h" file in i386/isa and the "pnp.h" file in my build directory. I eventually got it to work by giving i386/isa/pnp.h a different name and fiddling with the #include line in pnp.c.
