Hello I'm running FreeBSD 5.2.1 Release on a laptop computer equipped with the Intel ICH4 82801DB audio chipset. Sound doesn't work at all, and I have the following error message in the kernel log : pcm0: <Intel ICH4 (82801DB)> port 0xe100-0xe13f,0xe000-0xe0ff at device 31.5 on pci0 pcm0: unable to map IO port space device_probe_and_attach: pcm0 attach returned 6 I've searched the Web and mail archives, and tried to change the values of pci.allow_unsupported_io_range and hw.pci.enable_io_modes, without any effect. Some messages said that setting the BIOS to "Non PNP OS installed" can solve this problem, but I don't have this option in my BIOS, and no upgrade is available for it. When I boot with ACPI disabled, I still have the same error message, moreover the whole system crashes right after it with a general protection fault. The sound used to work under Linux. Thank you for your help, Sebastien
