2. Reset the system microprocessor by writing a 1 to bit 0.

3.Issue a Halt instruction to the system microprocessor.

4.Reenable all maskable and nonmaskable interrupts.

If you do not follow this procedure, the results are unpredictable.

Note: Whenever possible, use BIOS as an interface to reset the system microprocessor to the real mode. For more information about resetting the system microprocessor, referIBM toPersonalthe
