Integrate with Linux bootloader / boot process.

pin 0 on = normal boot, pin 0 off = single user mode.

pin 1 on = GRUB interactive screen enabled, pin 1 off = GRUB interactive screen disabled.

I had something like that hanging off a parallel port in a PC in 1990; it read the status bits of a printer port and booted accordingly. Could still do it today, via a $1 USB serial port's status bits.
