Superiotool README
-------------------------------------------------------------------------------
Superiotool is a user-space utility which can
- detect which Super I/O chip is soldered onto your mainboard,
- at which configuration port it's located (usually 0x2e or 0x4e), and
- dump all register contents of the Super I/O chip, together with the
default values as per datasheet (to make comparing the values easy).
It is mainly used for coreboot development purposes (see coreboot.org
for details on coreboot), but it may also be useful for other things.
Installation
------------
$ svn co svn://coreboot.org/repos/trunk/util/superiotool
$ cd superiotool
$ make
$ sudo make install
Usage
-----
$ superiotool [-d] [-e] [-l] [-V] [-v] [-h]
-d | --dump Dump Super I/O register contents
-e | --extra-dump Dump secondary registers too (e.g. EC registers)
-l | --list-supported Show the list of supported Super I/O chips
-V | --verbose Verbose mode
-v | --version Show the superiotool version
-h | --help Show a short help text
Per default (no options) superiotool will just probe for a Super I/O
and print its vendor, name, ID, revision, and config port.
Typical usage of superiotool:
- Probe/detect the Super I/O in your mainboard:
$ superiotool
- Register dump as table of hex-values of the Super I/O (if detected):
$ superiotool -d
Supported Super I/O Chips
-------------------------
Please see http://coreboot.org/Superiotool#Supported_devices, or type
$ superiotool -l
There's also a collection of sample register dumps from various Super I/O
chips on that web page. Please send further register dumps (either from a
proprietary BIOS and/or from coreboot) to the coreboot mailing list
(http://coreboot.org/Mailinglist).
