5 Superiotool is a user-space utility which can
7 - detect which Super I/O chip is soldered onto your mainboard,
9 - at which configuration port it's located (usually 0x2e or 0x4e), and
11 - dump all register contents of the Super I/O chip, together with the
12 default values as per datasheet (to make comparing the values easy).
14 It is mainly used for coreboot development purposes (see coreboot.org
15 for details on coreboot), but it may also be useful for other things.
21 $ svn co svn://coreboot.org/repos/trunk/util/superiotool
33 $ superiotool [-d] [-l] [-V] [-v] [-h]
35 -d | --dump Dump Super I/O register contents
36 -e | --extra-dump Dump Secondary registers too (like EC registers etc.)
37 -l | --list-supported Show the list of supported Super I/O chips
38 -V | --verbose Verbose mode
39 -v | --version Show the superiotool version
40 -h | --help Show a short help text
42 Per default (no options) superiotool will just probe for a Super I/O
43 and print its vendor, name, ID, revision, and config port.
45 Typical usage of superiotool:
47 - Probe/detect the Super I/O in your mainboard:
51 - Register dump as table of hex-values of the Super I/O (if detected):

59 Please see http://coreboot.org/Superiotool#Supported_devices, or type
63 There's also a collection of sample register dumps from various Super I/O
64 chips on that web page. Please send further register dumps (either from a
65 proprietary BIOS and/or from coreboot) to the coreboot mailing list
66 (http://coreboot.org/Mailinglist).
