INT 19 is to reload the disk boot. If a resident program has modified the interrupt vector before, directly using INT 19H will cause a system crash.
You can directly JMP FAR F000:FFF0. It can also be done through I/O. debug -a100 mov dx,0cf9 mov al,6;3 is for shutting down, but it is only effective after writing data to the CMOS shutdown status byte first. out dx,al int 20 -rcx:9 -n reboot.com -w -q [ Last edited by netwinxp on 2010-6-22 at 18:47 ] |
