Hi
I have been trying to get the W83627THF chip working on this
board. It is an Asus P4C800 with Intel 875p chipset and a
W83627THF connected via the SMBus.
There are no data sheet for the W83627THF as far as I can see,
but supposidly it is a W83627HF with advance Fan control, etc.
I have applied attached patches, and tried various other things
to get it to work, but no avail. The SMBus on the ICH5 seems to
work, and it seems to detect the sensor chip just fine, but it
do not seem to read any values from the W83627THF.
PCI ID:
--------------------------
Bus 0, device 31, function 3:
SMBus: PCI device 8086:24d3 (Intel Corp.) (rev 2).
IRQ 17.
I/O at 0x400 [0x41f].

Ask if more is needed.
