The 81.Em state-changed 82event will be sent to the 83.Pa /etc/powerd/scripts/sensor_drive 84script when such condition happens. 85.Sh SEE ALSO 86.Xr intro 4 , 87.Xr pci 4 , 88.Xr scsi 4 , 89.Xr sd 4 , 90.Xr bioctl 8 , 91.Xr envstat 8 , 92.Xr powerd 8 93.Sh HISTORY 94The 95.Nm 96driver first appeared in 97.Nx 4.0 . 98
