 	Further information:
 
 	FreeBSD's fdisk comes up with these values, which don't 
 correspond to sysinstall's guess or the values I copied from pfdisk 
 to sysinstall to reinstall. fdisk comes up with the same values both 
 with a non-booting system (booted from CD) and with a good system, 
 booted normally from BootEasy.
