  Modified:    sys/i386/boot/biosboot  bios.S
  Log:
  Preserve %esi and %edi for all BIOS calls.  This is probably only necessary
  for get_diskinfo(), whose BIOS call sets %es:%edi in some cases, although
  most documentation says that it doesn't change %edi in the cases that
  happened to matter (for hard disks).
  
  This shall be in 2.1.6 and 2.2.

  		(except I kept the unnecessary preservation of %edx and %ecx)
