  Modified:    sys/i386/boot/biosboot  bios.S
  Log:
  Initialize the upper 16 bits of the memory sizes properly (to 0).
  They were garbage that happened to be 0 in many cases.  (real_to_prot()
  happens to leave the value of the real-mode %cr0 in %eax and the
  memory-size BIOS calls usually don't touch the upper bits of %eax.
  The upper 16 bits of %cr0 are usually 0 at boot time, at least on
  486's.
  
  Should be in 2.2.
