Can the hlt instruction in assembly shutdown a computer it as it halts the processor? if it can be done using what i have told, is it the right way?
Can hlt shutdown the machine?
start:
xor ax, ax; ;clear ax
mov bx, ax; ;clear bx
cli ;stop all interrupts
hlt ;halt the cpu
If this is not the way to be done of if this will not shutdown the system please tell me the right way to do it.
The hlt instruction stops the x86 until an interrupt occurs. Unless all interrupts are disabled, that will stop the processor for only a millisecond or so.
To power down a modern computer, use the ACPI (Advanced Configuration and Power Interface).
