  Modified files:
    sys/boot/i386/btx/btx btx.S 
  Log:
  Emulate moving cr0, cr2, cr3, or cr4 into any i386 general register
  rather than just emulating mov cr0, eax.  This fixes some Compaq/HP BIOS
  with DMA (as the BIOS tried to read cr3 so it could translate addresses
  if paging was enabled).
