G760A(4)                     Device Drivers 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 representation and truncated.  For example when
             you are setting 2000 it will be truncated to 2006, and 8000 will
             be changed to 8057.
