NAME

     itesio -- ITE IT87xxF Super I/O driver

SYNOPSIS

     itesio0 at isa? port 0x2e
     itesio1 at isa? port 0x4e

DESCRIPTION

     The itesio driver provides support for the Environment Controller and the Watchdog Timer on the IT87xxF Super I/Os, and may be used to moni-
     tor hardware sensors or setting up a watchdog timeout value for the system.

     The itesio driver has 15 sensors:

	   Sensor    Units    Typical Use
	   Temp0     uK       CPU Temp
	   Temp1     uK       System Temp
	   Temp2     uK       Aux Temp
	   VIN0      uV DC    Vcore A
	   VIN1      uV DC    Vcore B
	   VIN2      uV DC    +3.3V
	   VIN3      uV DC    +5V
	   VIN4      uV DC    +12V
	   VIN5      uV DC    -12V
	   VIN6      uV DC    -5V
	   VIN7      uV DC    STANDBY
	   VBAT      uV DC    VBAT
	   Fan0      RPM      CPU Fan
	   Fan1      RPM      System Fan
	   Fan2      RPM      Aux Fan

     The itesio Watchdog Timer is configurable via the wdogctl(8) utility and has a resolution between 1 and 65535 seconds.  The Watchdog Timer is
     not supported on the IT8705 Super I/O.

HISTORY

     The itesio driver first appeared in OpenBSD 3.4 and was then ported to NetBSD 4.0.

AUTHORS

     The itesio driver was written by Julien Bordet <zejames@greyhats.org> and Juan Romero Pardines <xtraeme@netbsd.org>.

BUGS

     Interrupt support is unimplemented.

NAME

     lm -- National Semiconductor LM78, LM79 and compatible hardware monitors

SYNOPSIS

     lm0 at isa? port 0x280 flags 0x00
     lm1 at isa? port 0x290 flags 0x00
     lm2 at isa? port 0x310 flags 0x00
     lm3 at isa? port 0xa00 flags 0x00
     lm0 at pnpbios0 index ? flags 0x00
     lm0 at iic? addr 0x2e flags 0x00
     lm* at wbsio?

DESCRIPTION

     The lm driver provides support for the National Semiconductor LM series hardware monitors and register compatible chips to be used with the
     envsys(4) API.

     Most supported devices possess 11 sensors:

	   Sensor    Units    Typical Use
	   IN0	     uV DC    Core voltage
	   IN1	     uV DC    unknown
	   IN2	     uV DC    +3.3V
	   IN3	     uV DC    +5V
	   IN4	     uV DC    +12V
	   IN5	     uV DC    -12V
	   IN6	     uV DC    -5V
	   Temp      uK       Motherboard Temperature
	   Fan0      RPM      Fan
	   Fan1      RPM      Chassis Fan
	   Fan2      RPM      Fan
     for some devices (most Winbond devices) sensor names and numbers will be different.

     Due to hardware limitations, fresh sensor data is only available every 2 seconds.

HARDWARE

     Chips supported by the lm driver include:

	   National Semiconductor LM78, LM78-J, LM79 and LM81.

	   Winbond W83627HF*, W83627THF*, W83627EHF*, W83627DHG*, W83637HF*, W83697HF*, W83781D, W83782D*, W83783S*, W83791D*, W83791SD and
	   W83792D.

	   ASUS AS99127F.

     For most of the Winbond chips (identified with a * above), the flags configuration option can be specified to select the type of temperature
     sensor:

	   flags    Sensor Type
	   0	    Thermistor diode (Power-On default)
	   1	    Pentium-II diode
	   2	    2N3904 Bipolar
	   4	    Thermistor diode

HISTORY

     The lm device appeared in NetBSD 1.5.

BUGS

     Interrupt support is unimplemented.

     There are currently no known pnpbios IDs assigned to LM chips.
