I think your problem is that you have not searched this mailing list archives. This answer about sound card and my previous msg about nic and modem pci cards not being found are in the archives. You really should do some home work and search the archives before asking questions. I believe the unknown device FAQ is for pci Nics and pci Modems. Sound cards are different story. I've found that FreeBSD 4.x so far has supported every odd sound card I've thrown its way. Even (especially!) those on-board sound things built into motherboards and laptops these days. FreeBSD supports them all (and Windows usually doesn't without the special CD-Rom from the motherboard manufacturer.) Just add "device pcm" to your kernel conf file, build a new kernel, and I'll bet almost any sound card will work on reboot. -----Original Message----- From: Charles Howse [mailto:chowse@charter.net] Sent: Saturday, November 08, 2003 2:17 PM To: fbsd_user@a1poweruser.com; freebsd-questions@freebsd.org Subject: RE: Resolving IRQ conflicts with 4.8 > The problem you describe is becoming common in the 4.x versions of > FBSD. > I have seen these solutions voiced previously in this list. > > 1.

Moving the modem away from the last PCI slot allowed it to be detected. I still have the on-board sound device listed as "unknown", so I have jumped from your suggestion #2 to #6. (Device listed as "unkown".) I have not recompiled the kernel yet. I have refered to the FBSD FAQ you referenced, and have an issue there. Pnpinfo does not list any PnP devices, so I have to use pciconf -vl. Here is it's output re the sound card: none0@pci0:18:0: class=0x040100 card=0x13711274 chip=0x13711274 rev-ox08 hdr=0x00 Vendor = 'Creative (was: Ensoniq)' Device = 'ES1371, ES1373 Audio PCI' Class = multimedia Subclass = audio (I've typed this from my notes, capitals and tabs may be incorrect.) The FAQ says: [snip] Alternatively, if pnpinfo(8) does not list the card in question, pciconf(8) can be used instead. This is part of the output from pciconf -vl for an onboard sound chip: # pciconf -vl chip1@pci0:31:5: class=0x040100 card=0x00931028 chip=0x24158086 rev=0x02 hdr=0x00 vendor = 'Intel Corporation' device = '82801AA 8xx Chipset AC'97 Audio Controller' class = multimedia subclass = audio Here, you would use the chip value, ``0x24158086''. [snip] You should first make a backup of sio.c just in case things go wrong. You will also need it to make the patch to submit with your PR (you are going to submit a PR, are you not?) then edit sio.c and search for the line static struct isa_pnp_id sio_ids[] = { then scroll down to find the correct place to add the entry for your device. The entries look like this, and are sorted on the ASCII Vendor ID string which should be included in the comment to the right of the line of code along with all (if it will fit) or part of the Device Description from the output of pnpinfo(8): {0x0f804f3f, NULL}, /* OZO800f - Zoom 2812 (56k Modem) */ {0x39804f3f, NULL}, /* OZO8039 - Zoom 56k flex */ {0x3024a341, NULL}, /* PMC2430 - Pace 56 Voice Internal Modem */ {0x1000eb49, NULL}, /* ROK0010 - Rockwell ? */ {0x5002734a, NULL}, /* RSS0250 - 5614Jx3(G) Internal Modem */ Add the hexadecimal Vendor ID for your device in the correct place, save the file, rebuild your kernel, and reboot. Your device should now be found as an sio device as it was under FreeBSD 3.X My issue is: Apparently, it is important to add the new listing in the correct place in sio.c, as well as adding the ASCII Vendor ID String. Since I had to get the device info from pciconf instead of pnpinfo, I have no 7 character ASCII Vendor ID String (like RSS0250 in the listed example above). There is no example on how to format a new entry if you only have the output from pciconf. So...how should my new entry look and where should I place it in sio.c?
