# acpi\_aiboost(4freebsd)

ASUS AI Booster hardware monitor

## 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)](/loader.conf/5.md):

```
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 backend to fetch sensor values and descriptions and provides its data via the [sysctl(8)](/sysctl/8.md) interface, under dev.acpi\_aiboost.0 namespace. Descriptions 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)](/acpi/4.md), [sysctl.conf(5)](/sysctl.conf/5.md) [sysctl(8)](/sysctl/8.md)

## 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 automatic/manual fan mode).
