| I'm using GCC/DJGPP and I'd like to reboot the PC.  I've tried the
| following methods:
| 
| 1) int 0x19

This is not a good idea. Some programs hook this interrupt.

| 2) outportb(0xCF9, 4);
|    outportb(0xCF9, 2);

Why would you want to write to the PCI bus?

| 
| 3) void (*rebooter)();
|    rebooter = (void *) (0x00000000);
|    (*rebooter)();

Again, not a good idea for protected mode programs. In real mode, this
would be perfect.

You can try this one:

outportb (0x61, 0xfe);

It resets the CPU.
