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 backend to fetch sensor values and descriptions and provides its data via the sysctl(8) 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 |

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).
