Seeing as the PIC only operates at 10 Mhz and the network operates at 100
Mhz and because of the nature of the PIC's I/O ports, it would take 10
times it's CPU power to handle the 100 BaseT network... :> (and that's
using it's entire CPU only to read the port. In intel machines it's
different because you've got a fairly wide bus (all 100 baset cards i know
are PCI) so you've got at least 32 bits, and most PCI bus machines allow 64
(however, the spec says it only requies 32...but whatever :)
