Tests the reliability of the extended Int13 BIOS.  For every physical
drive installed in the sytem, reads several randomly selected sectors
as well as the first and last physical sector using both standard and
extended Int13 calls, then compares the results.  All sectors read on
all drives should match perfectly.  If ANY do NOT match, do NOT use
extended Int13 calls.  (NOTE: the user must press a key after each
sector is read.)
