POWER(4)               OpenBSD Programmer's Manual (SGI)              POWER(4)

NAME
     power - power button

SYNOPSIS
     power0 at macebus0 irq 6

DESCRIPTION
     The SGI O2 machines generate an interrupt when the power button on the
     front panel is pressed.  The power driver catches that interrupt.  If the
     machdep.kbdreset sysctl(8) is set to 1, power will then signal init(8) to
     do a clean shutdown(8).

SEE ALSO
     intro(4), macebus(4), init(8), rc.shutdown(8), sysctl(8)

HISTORY
     Support for the power driver first appeared in OpenBSD 4.3.

     The power driver was written by Jasper Lievisse Adriaanse
