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

NAME
     power - power button

SYNOPSIS
     power0 at macebus0 (O2)
     power0 at mainbus0 (Octane)

DESCRIPTION
     The SGI O2 and Octane machines generate an interrupt when the power but-
     ton on the front panel is pressed.  The power driver catches that inter-
     rupt.  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
