I8kctl, i8kfan \- Utility to access SMM BIOS and DMI table information from Dell
laptops
.SH "SYNTAX"

.SH "DESCRIPTION"
.LP
The i8kctl utility provides a command\-line interface to the i8k kernel
module. When invoked without arguments the
program reports the same information which can be read from the
\fB/proc/i8k\fR file:
.IP
1.  i8k format version
.br
2.  bios version
.br
3.  service tag (later 'machine id')
.br
4.  cpu temperature
.br
5.  left fan status
.br
6.  right fan status
.br
7.  left fan speed
.br
8.  right fan speed
.br
9.  ac power status
.br
10. fn buttons status
.LP
The optional command argument can be used to select only one of the
above items. Command can be: \fBversion\fR, \fBbios\fR, \fBid\fR,
\fBtemp\fR, \fBfan\fR, \fBspeed\fR, \fBac\fR and \fBfn\fR. Examples:
.IP
$ i8kctl
.br
1.0 A17 B5W123K 52 2 1 8040 6420 1 2
.IP
$ i8kctl temp
.br
52
.IP
$ i8kctl fan
.br
2 1
.LP
The \fBfan\fR command can accept two optional parameters which specify
the new fan state for left and right fans. The state parameter can be:
.IP
0  turn the fan off
.br
1  set low speed
.br
2  set high speed
.br
\-  don't change the state of this fan
.LP
For example the command:
.IP
$ i8kctl fan \- 2
.LP
sets the right fan to high speed and leaves the left unchanged.
It should be noted that if the \fBi8kmon(1)\fR daemon is used to
control the fans, setting the speed with i8kfan is pointless since the
daemon override regularly the speed with its own value.
.LP
Invoking i8kctl as i8kfan is the same as invoking the program with
the fan option:
.IP
$ i8kctl fan 1 2
.br
1 2
.IP
$ i8kfan 1 2
.br
1 2
