-----BEGIN PGP SIGNED MESSAGE----- There is an article in the latest c't computer magazin about a bug called 'Hidden CLI' in all the 6x86 CPUs including M2. As I do not have access to such a CPU I can't verify it. The code: MOV BX,70h STI again: XCHG AX,[BX] MOV DX,AX JMP again The CPU hangs ignoring all interrupts.
