[comp.sys.ibm.pc.misc] Identity CPU type.

frankhua@cs.mcgill.ca (Frank X.J HUANG) (04/03/91)

Hi there! I got a problem. I want to add a math coprocessor on my 386 but
don't know what's the _Frequency_ (20 or 25 MHz) of the CPU. Is there
anyway to get this info.? How?

Thanx alot.

Try looking at it... should have a -20 or -25 following the part 
number identifying which one it is.  You could also look at the 
chrystals on the motherboard.  Should find one that's twice the CPU 
speed (40 or 50MHz).  If you don't want to open the thing up you can 
try using a speed tester such as Norton's SI or SPEED.COM available 
just about anywhere.
