       acpihelp - ACPI help utility


       acpihelp <option>...  [<name-prefix>|<hex-value>]


       This manual page briefly documents the acpihelp command. The option list is taken from the
       acpihelp interactive help.

       acpihelp provides descriptive text for AML and ASL keywords, methods, and opcodes.

       Much more detailed documentation may be found at

       If neither a <name-prefix> or a <hex-value> is provided,  acpihelp  will  do  the  logical
       equivalent of a "display all."

       A  default  search  (that  is,  a search with no options) and a <name-prefix> can mean two
       different things: (1) if <name-prefix>  does  not  start  with  an  underscore,  find  ASL
       operator names, or (2) if <name-prefix> does start with an underscore, find ASL predefined
       method names.
