The other way to tell is by the machine designation number:

	4D/cp0	c = system processor "class"
		p = # of processors

Following this designation scheme you have:

	4D/210	1 processor
	4D/220	2 processors
	4D/240	4 processors

	4D/310	1 processor
	4D/320	2 processor
	4D/340	4 processor
	4D/380	8 processor

If your system had an upgrade to two processors, the label might say 4D/210
but hinv, osview, and gr_osview should all indicate two processors.  hinv
should report:

	2 25 MHZ IP7 Processors
