G760A(4)                   Kernel Interfaces Manual                   G760A(4)

NAME
     g760a -- Global Mixed-mode Technology Inc. G760a fan speed controller
     driver

SYNOPSIS
     g760a0 at iic? addr 0x3e

DESCRIPTION
     The g760a driver provides support for the Global Mixed-mode Technology
     Inc. G760a on iicbus fan speed controller to be used with the envsys(4)
     API.  This chip could be found in D-Link's DNS-323 NAS box.

     The following sysctl(8) variable controls the fan's speed:

     machdep.g760a0.rpm
                   This value specifies the desired speed for the fan.  Valid
                   range is 2000..20000 or 0 (the fan is turned off).  The
                   default value is 0.

                   When setting the desired speed the RPM number will be
                   converted to the internal represenation and truncated.  For
                   example when you are setting 2000 it will be truncated to
                   2006, and 8000 will be changed to 8057.
