I am definitely not getting that kind of accuracy.

I got to digging last night and found some 20mhz  crystals on some network
cards.
One is clearly marked 20.0000M and the is very small and lowprofile and
labeled FS20.00.

I assume that the second one is 20mhz as well.  Do most all 10Mbit ethernet
cards have a 20mhz crystals?

I have three different brands here and they all look like this is the case.
