Hi Justin,

Sorry for the late reply.

The temp value is returned in the EAX register (0xC000002) but in your
case it's all zero. I don't know why that is. I also noticed, that
your CPU has a 0xC000003 perf register whereas my datasheet only
defines perf registers up to 0xC0000002. I'll try to get a newer
datasheet from VIA, maybe something changed.

There's nothing more I can do at the moment, sorry.

...juerg
