John, Here are the results you asked for. You will seein the acpi boot the isa_get_logicalid(dev) returns 0 for a probe call to the non-pnp routine mss_probe dmesg excerpt ... mss_probe: bus acpi0 is probing device pcm0 mss_probe: isa_get_logicalid() returned 0! mss_probe: no address given, try 0x530 mss_detect - chip revision 0x0a mss_detect() - Detected CS4236 pcm0: <CS4236> port 0x530-0x537 on acpi0 device_attach: pcm0 attach returned 6 mss_probe: bus acpi0 is probing device pcm1 ... Here are the changes I made for debugging output to the two probe routines in mss.c static int mss_probe(device_t dev) { u_char tmp, tmpx; int flags, irq, drq, result = ENXIO, setres = 0; struct mss_info *mss; printf("mss_probe: bus %s is probing device %s\n",device_get_nameunit(device_get_parent(dev)),device_get_nameunit(dev)); // result = ISA_PNP_PROBE(device_get_parent(dev), dev, mss_ids); // if (result!=ENOENT) return ENXIO; /* only continue if the device is not pnp */ /* old way- not so good for ACPI: */ if (isa_get_logicalid(dev)) return ENXIO; printf("mss_probe: isa_get_logicalid() returned 0!\n"); .... and static int pnpmss_probe(device_t dev) { u_int32_t lid, vid; int result; lid = isa_get_logicalid(dev); vid = isa_get_vendorid(dev); printf("pnpmss_probe: bus %s is probing device %s lid %lxh, vid %lxh\n",device_get_nameunit(device_get_parent(dev)),device_get_nameunit(dev),lid,vid); if (lid == 0x01000000 && vid != 0x0100a90d) /* CMI0001 */ return ENXIO; result = ISA_PNP_PROBE(device_get_parent(dev), dev, pnpmss_ids); if (result == 0) { if ((lid == 0x630e) && ((vid&0xff000000) == 0x35000000)) { device_set_desc(dev, "CS4236B"); } } printf("pnpmss_probe result %d\n",result); return result; } Here is the verbose dmesg with acpi on in the bios. I appended to it a cat /dev/sndstat. Note it has loaded the sound driver as pcm3 Copyright (c) 1992-2005 The FreeBSD Project.
