System: FreeBSD yebisu.j.dendai.ac.jp 4.6-STABLE FreeBSD 4.6-STABLE #26: Tue Aug 13 00:25:35 JST 2002 root@yebisu.j.dendai.ac.jp:/usr/src/sys/compile/XPSMP i386
>Description:
The attached patch for sys/pci/amdpm.c enables kernel to recognize
AMD766/768 SMBus interface. AMD766/768 SMBus seems to be compatible with
that of AMD756, and so the patch just adds PCI device IDs and modifies
one conditional.
>How-To-Repeat:
It works fine with ASUS A7M266-D (AMD768 chipset) and ports/sysutils/xmbmon,
though I never examined with AMD766 or other applications.
