34 -d | --dump Dump Super I/O register contents\n\
35 -e | --extra-dump Dump secondary registers too (e.g. EC registers)\n\
36 -l | --list-supported Show the list of supported Super I/O chips\n\
37 -V | --verbose Verbose mode\n\
38 -v | --version Show the superiotool version\n\
39 -h | --help Show a short help text\n\n"
42 Per default (no options) superiotool will just probe for a Super I/O\n\
43 and print its vendor, name, ID, revision, and config port.\n"
