1 .TH SUPERIOTOOL 8 "January 18, 2008"
3 superiotool \- Super I/O detection tool
5 .B superiotool \fR[\fB\-dlVvh\fR]
8 is a GPL'd user-space utility which can
10 * detect which Super I/O chip is soldered onto your mainboard,
12 * at which configuration port it's located (usually 0x2e or 0x4e), and
14 * dump all register contents of the Super I/O chip, together with the
15 default values as per datasheet (to make comparing the values easy).
17 It is mainly used for coreboot development purposes (see coreboot.org
18 for details on coreboot), but it may also be useful for other things.
20 The list of supported Super I/O chips is available at
21 .BR http://coreboot.org/Superiotool#Supported_devices ","

23 .BR "superiotool -l" "."

33 Dump Super I/O registers (if the Super I/O chip is detected and
37 option for this chip). The output will look something like this:

91 is scanning, but also at which configuration port it's probing, and which
92 Super I/O initialization sequence is used. If no Super I/O was detected
93 in a probing run, the returned output will be shown, as it may be useful
94 for figuring out which (currently unrecognized) Super I/O chip this may be.
