hi,
On a PCChips M720 dual celeron board there are 2 (identical) celerons installed,
yet on bootup all kernels (several 2.3.x's and 2.4.0's) i've tried so far will
identify CPU1 as a mobile P-II.
Switching cpu's doesn't make a difference as far as identification is concerned.
The system itself has proven to be stable, but is there something i can do
to make it recognize both cpu's correctly?
