ÔHE CODE SAMPLES GIVEN HERE SHOW HOW TO SWITCH ÒÁÍÌINK AND ÒÁÍÄRIVE
ÒÏÍ MODES. ÔHIS CODE COULD BE INCLUDED INTO MACHINE LANGUAGE PROGRAMS
WHICH ATTEMPT TO SWITCH THE COMPUTER FROM 128 TO 64 MODE (SOMETIMES
FOUND IN 128 BOOT SECTORS). ÒÁÍÌINK OR ÒÁÍÄRIVE SHOULD BE SWITCHED

64 TO 128 IS NOT REALLY POSSIBLE. ÔHE ONLY POSSIBLE ADVANTAGE OF
SWITCHING ÒÁÍÌINK OR ÒÁÍÄRIVE IN THIS MANNER WOULD BE TO GAIN ACCESS
TO 128 ÒÏÍ CODE FROM 64 MODE. ÉF YOU CAN THIN OF A GOOD USE FOR SUCH
ACCESS, GO FOR IT.
