     Does anyone have assembly source for a *detailed* detection of
the CPU of a machine?  I mean not just 8086 vs. 286/386/486, but
distinguishing a 386 or 486DX from an SX, and perhaps a NEC V20 (?)
from an 8088/8086, as well as coprocessor type (if present).  The
method mentioned in the FAQ, in VOL10N20.ZIP (PC Magazine archive) on
simtel, distinguishes between 8086/286/386/486 and floating point
types, but I'd like a way to detect 386SX vs. 386DX chips, and NEC chips vs.
Intel's.  I'm writing a system-information program similar to Norton's
SI.  Anyone know of any sources?  advTHANXance.
