ACPI_AIBOOST(4) BSD Kernel Interfaces Manual ACPI_AIBOOST(4)NAME
acpi_aiboost -- ASUS AI Booster hardware monitor
SYNOPSIS
To compile this driver into the kernel, place the following line in your kernel configuration file:
device acpi_aiboost
Alternatively, to load the driver as a module at boot time, place the following line in loader.conf(5):
acpi_aiboost_load="YES"
DESCRIPTION
The acpi_aiboost driver provides support for monitoring the hardware sensors in recent ASUS motherboards. The driver uses ACPI as the back-
end to fetch sensor values and descriptions and provides its data via the sysctl(8) interface, under dev.acpi_aiboost.0 namespace. Descrip-
tions for these values are available with sysctl -d.
The acpi_aiboost driver typically has 7 sensors, depending on the motherboard and chipset:
Sensor Units Typical Use
CPU uK CPU Temperature
MB uK MB Temperature
VCC uV DC Core Voltage
+3.3V uV DC +3.3 Voltage
+5V uV DC +5 Voltage
+12V uV DC +12 Voltage
CPU RPM CPU Fan
SEE ALSO acpi(4), sysctl.conf(5)sysctl(8)HISTORY
The acpi_aiboost driver first appeared in FreeBSD 7.0.
AUTHORS
The acpi_aiboost driver was written by Takanori Watanabe. This manual page was written by Juan Romero Pardines, who adapted the code for
NetBSD, and adopted back to FreeBSD by Takanori Watanabe.
BUGS
It's possible to modify voltages via the ACPI methods in the DSDT, but for now the driver only reports the sensors' values. CPU Q-Fan is
another thing that is typically specified in the ACPI namespace, and in the future we should handle this feature (to enable or disable auto-
matic/manual fan mode).

AIBS(4) BSD Kernel Interfaces Manual AIBS(4)NAME
aibs -- ASUSTeK AI Booster ACPI ATK0110 voltage, temperature and fan sensor
SYNOPSIS
To compile this driver into the kernel, place the following lines in your kernel configuration file:
device acpi
device aibs
Alternatively, to load the driver as a module at boot time, place the following lines in loader.conf(5):
acpi_load="YES"
aibs_load="YES"
DESCRIPTION
The aibs driver provides support for the voltage, temperature and fan sensors available through the ATK0110 ASOC ACPI device on ASUSTeK moth-
erboards. The number of sensors of each type, as well as the description of each sensor, varies according to the motherboard.
The driver supports an arbitrary set of sensors, provides descriptions regarding what each sensor is used for, and reports the current values
as well as the supposed range specifications of each sensor's input as defined by the motherboard manufacturer through ACPI.
The range specifications are as follows:
o Voltage sensors have a lower and an upper range specification.
o Temperature sensors have two upper specifications.
o Fan sensors may either have only the lower specification, or, depending on the DSDT, one lower and one upper specification.
Sensor readings and the range specifications are made available through the sysctl(3) interface, and can be monitored with sysctl(8). For
example, on an ASUS V3-P5G965 barebone:
> sysctl dev.aibs.0.{volt,temp,fan}
dev.aibs.0.volt.0: 1192 850 1600
dev.aibs.0.volt.1: 3312 2970 3630
dev.aibs.0.volt.2: 5017 4500 5500
dev.aibs.0.volt.3: 12302 10200 13800
dev.aibs.0.temp.0: 28.0C 80.0C 95.0C
dev.aibs.0.temp.1: 55.0C 60.0C 95.0C
dev.aibs.0.fan.0: 878 600 7200
dev.aibs.0.fan.1: 0 700 7200
> sysctl -d dev.aibs.0.{volt,temp,fan}
dev.aibs.0.volt:
dev.aibs.0.volt.0: Vcore Voltage
dev.aibs.0.volt.1: +3.3 Voltage
dev.aibs.0.volt.2: +5 Voltage
dev.aibs.0.volt.3: +12 Voltage
dev.aibs.0.temp:
dev.aibs.0.temp.0: CPU Temperature
dev.aibs.0.temp.1: MB Temperature
dev.aibs.0.fan:
dev.aibs.0.fan.0: CPU FAN Speed
dev.aibs.0.fan.1: CHASSIS FAN Speed
Generally, sensors provided by the aibs driver may also be supported by certain other drivers or utilities that access the ISA / LPC or I2C /
SMBus devices directly. The precise collection of aibs sensors is comprised of the sensors specifically utilised in the motherboard design,
which may be supported through a combination of one or more physical hardware monitoring chips.
The aibs driver, however, provides the following advantages when compared to the native hardware monitoring drivers or other utilities:
o Sensor values from aibs are expected to be more reliable. For example, voltage sensors in many hardware monitoring chips can only sense
voltage from 0 to 2 or 4 volts, and the excessive voltage is removed by the resistors, which may vary with the motherboard and with the
voltage that is being sensed. In aibs, the required resistor factors are provided by the motherboard manufacturer through ACPI; in the
native drivers, the resistor factors are encoded into the driver based on the chip manufacturer's recommendations. In essence, sensor
values from aibs are very likely to be identical to the readings from the Hardware Monitor screen in the BIOS.
o Sensor descriptions from aibs are more likely to match the markings on the motherboard.
o Sensor range specifications are supported by aibs. The range specification is reported for each individual sensor as suggested by the
motherboard manufacturer. For example, the threshold for the CPU temperature sensor is likely to be significantly higher than that for
the chassis temperature sensor.
o Support for newer chips in aibs. Newer chips may miss a native driver, but should be supported through aibs regardless.
