I am running FreeBSD src-cur-3027. As I have an old 486 motherboard, with no plug&play bios, it was the lines - the parameters for the PnP device(s) will be read from the [...] if you have a broken (or no) PnP bios your only chance is to patch the pnp attach code in the driver for your card (ad1848.c, sb_dsp.c, clones.c) and write there the parameters you want; in the README file that really got me interested. So, I went ahead with sb_dsp.c. in the function sb16pnp_attach, I inserted the following lines (marked with +) read_pnp_parms ( &d , 0 ) ; + d.irq[0] = 7; + d.drq[0] = 3; d.drq[1] = 5; + d.port[0] = 0x220; d.port[1] = 0x330; d.port[2] = 0x388; dev->id_iobase = d.port[0]; write_pnp_parms ( &d , 0 , 1); [Information from pnpinfo attached at the end of the e-mail]. I have also tried other legal combinations (irq 5). It seems that both isa_dmastatus() and isa_dmastop() have been checked into src-cur-3027, so I did not need to patch isa.c, only autoconf.c, files.i386 and of course, copying pnp.c and pnp.h. I inserted these two lines in my kernel config file: controller pnp0 device pcm0 at isa? port? tty irq 7 drq 1 vector pcmintr The kernel compiles and boots just fine, and it even looks as if some of the stuff is actually working.

Cold reboots have the line "port 0x0000 0x0000 0x0000 ...") after the "CSN 1 Vendor ID: ..." line. Now, my questions are . Why is the card attached as pcm1 ? . After ./MAKEDEV snd1, if I try to use /dev/audio1 (i.a. cat a random file to /dev/audio1) etc., I get messages like default ioctl snd1 subdev 4 fn 0x402c7413 fail default ioctl snd1 subdev 4 fn 0x402c7413 fail got sbintr for unit 1, flags 0x00000461 default ioctl snd1 subdev 4 fn 0x402c7413 fail default ioctl snd1 subdev 4 fn 0x402c7413 fail got sbintr for unit 1, flags 0x00000461 default ioctl snd1 subdev 4 fn 0x402c7413 fail default ioctl snd1 subdev 4 fn 0x402c7413 fail in the syslog. Am I doing something totally wrong, here? Shouldn't this work? Is there no way to get a PNP card working under FreeBSD when I have no PNP bios?
