Terry -- Replying to: No. These configurations do not exist anywhere but the Windows 95 Registry. They are not attributes of the card. I'm confused, then. It appears that the "pnpinfo" program is getting detailed info on multiple configurations from the sound card. If the configurations are not attributes of the card, then what is "pnpinfo" seeing when it reads and reports "Dependent Function" material? The "Configuration 0" is not real in Windows 95, either: it exists solely as the result of the BIOS PnP configura- tion for the device. Please note, BTW, that I do =not= have Windows 95 on my system. In addition to FreeBSD, I have a partition with DOS 6.22 and Windows 3.1, which I use solely for running a few "legacy" apps. When I said the default configuration info I was talking about was the same as Win95's "configuration 0", I didn't mean to imply that I was actually running Win95. Apologies if I confused anyone. This is not going to happen. The PnP card is being con- figured by the PnP BIOS as the first unallocated interrupt for which the graph soloution is non-conflicting with other PnP hardware, and for which the PnP BIOS does not have defined ISA devices. In other words, it's 5 because the BIOS believes 5 is free. Well, I went into the BIOS and reconfigured the on-board parallel port (normally at 378H/IRQ7) to be 378H/IRQ5. I rebooted with my "SB16 uses IRQ10" kernel, but the sound card wouldn't work. I then ran "pnpinfo", and the first configuration listed by "pnpinfo" still gave IRQ5 as the one and only available IRQ -- even though I had set up the on-board parallel port to use IRQ5. This is a different problem, then. If the sound card is not PnP, then moving the IRQ in the configuration probably does not change the IRQ used by the sound card, unless you have very smart drivers. My sound card =is= PnP. At least, it claims to be, and "pnpinfo" sees it. What I was trying to say is that it's an ISA PnP card (not a PCI PnP card).
