NAME

     adm1026hm -- Analog Devices ADM1026 complete thermal system management
     controller


SYNOPSIS

     adm1026hm* at iic0 addr 0x2e: ADM1026 hardware monitor: rev. 0x4, step.
           0x5
     adm1026hm*: 8 fans, 3 temperatures, 15 voltages


DESCRIPTION

     The adm1026hm driver provides support for the Analog Devices ADM1026
     hardware monitor.  The chip possesses 8 fan speed sensors, 3 temperature
     sensors, and 17 voltage sensors.  The number of each sensor type config-
     ured by the driver depends on the chip configuration.

     The values of the sensors are made available through the envstat(8)
     interface.

     The adm1026hm driver was written by Julian Coleman <jcoleman@NetBSD.org>.


BUGS

     It's not possible to determine if either a sensor is not connected, or
     the monitored device is producing no output.  Therefore, unconnected sen-
     sors will show outputs of 0.

     The adm1026hm driver does not support checking or altering limit values,
     interrupt output, nor the built-in EEPROM.
