The most recent version is 1.3 (from Oct. 1990).  That works OK.
Note that an incomplete distribution of pfdisk has been propagated
around, somewhat to my dissapointment, because it omitted what I
consider some of the more clever parts of package.
The full release of pfdisk is available from:
	ftp.mc.com://pub/pfdisk-1.3.tar.Z

The DOS implementation of getGeometry() in pfdisk actually reports the
"highest cylinder number" from the BIOS. (Yes, this is a bug).
You can override the geometry to set cylinders to the correct value.

Cylinders and tracks are numbered from zero, sectors from one.
