HLT -> ENTER HALT STATE
halt puts the 80386 in a HALT state by stopping instruction execution. Execution is resumed by an nmi or an enabled interrupt. After a halt, if an interrupt is used to continue execution, the saved CS:EIP or CS:IP value points to the next instruction (after the halt).
The halt instruction is privileged.
