what do u mean ?
winxp is another OS and so is DOS
apart from the fact that windows no longer has native dos support
i suppose ur talkin abt the "boot to command prompt" option when u press f8 during sustem bootup
u can no longer do this
u want to boot into dos ? ull need a bootable floppt ( just to get the command prompt)
apart from this i think u'll have to actually install a dos OS as a dual boot
