Is there a way (within a C program) to detect which CPU is installed in a
system and what the clock speed is?  Is there any public domain source
code available for this?

Thanks.

It's pretty much covered in The Undocumented PC, but most of the
work is done in assembler; and you may well need to hit eg. i/o
ports.  It's a long time since I've looked at this, and I don't
have the book here, but I'd check it out.  It's part of the 
Andrew Schulmann (?sp) Undocumented Whatever series.
