$ superiotool
|
||||
$ superiotool [-d] [-V] [-v] [-h]
|
||||
|
||||
Currently the tool will automatically try to detect which Super I/O you
|
||||
have, and also dump the register contents.
|
||||
-d | --dump Dump Super I/O registers
|
||||
-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, version, and config port.
|
||||
|
||||
Typical usage of superiotool:
|
||||
|
||||
- Probe/detect the Super I/O in your mainboard:
|
||||
|
||||
$ superiotool
|
||||
|
||||
- Detailed register dump of the Super I/O (if detected):
|
||||
|
||||
$ superiotool -d
|
||||
|
||||
|
||||
