Let's see, the Intel architecture says segment:offset is actually
segment << 4 + offset, so:

raymond@math.berkeley.edu	kdq@demott.COM
FFFF:FFFF is   FFFF0		F000:FFFF is  F0000
              + FFFF			     + FFFF
              -----			     ------
              10FFEF			      FFFFF

Second form looks lots more correct to me.
