Chip IT8705F/IT8712F or SIS950 found. As far as I can tell (from http://www.giga-byte.com/MotherBoard/Products/Products_GA-7VT880-L.htm), your MB uses VT8237 as south bridge. Quoting from `man viapm`: > This driver provides access to the VIA chipset Power Management Unit fam- > ily. They are VT82C586B, VT82C596A, VT82C596B, VT82C686A and VT8233. So I guess you are out of luck. As further investigation, you may want to look in /usr/src/sys/pci/viapm.c. You'll find: > #define VIA_586B_PMU_ID 0x30401106 > #define VIA_596A_PMU_ID 0x30501106 > #define VIA_596B_PMU_ID 0x30511106 > #define VIA_686A_PMU_ID 0x30571106 > #define VIA_8233_PMU_ID 0x30741106 > #define VIA_8233A_PMU_ID 0x31471106 If you do "pciconf -l", you should get a list like the following: > agp0@pci0:0:0: class=0x060000 card=0x00000000 chip=0x03051106 rev=0x02 hdr=0x00 > pcib1@pci0:1:0: class=0x060400 card=0x00000080 chip=0x83051106 rev=0x00 hdr=0x01 > isab0@pci0:7:0: class=0x060100 card=0x00001106 chip=0x06861106 rev=0x40 hdr=0x00 > viapropm0@pci0:7:4: class=0x068000 card=0x30571106 chip=0x30571106 rev=0x40 hdr=0x00 ^^^^^^^^^^^^^^^^^^^^^ > ahd0@pci0:9:0: class=0x010000 card=0x00429005 chip=0x80129005 rev=0x03 hdr=0x00 > ahd1@pci0:9:1: class=0x010000 card=0x00429005 chip=0x80129005 rev=0x03 hdr=0x00 > fxp0@pci0:11:0: class=0x020000 card=0x00408086 chip=0x12298086 rev=0x0c hdr=0x00 > none0@pci1:0:0: class=0x030000 card=0x00000000 chip=0x002c10de rev=0x15 hdr=0x00 As you can see, I have a chip=0x30571106, which corresponds to VIA_686A_PMU_ID, so my chipset is supported by viapm. If you see a different value, not listed in the above defines, the driver won't pick that chip up. bye av.
