CSV output: (there are more headings available for each of these path's, these are examples. For full headers, type /? after "get" to recieve a full list.)
For Example:
C:\>wmic BIOS get /?

The following GET switches are available:
/VALUE                       - Return value.
/ALL(default)                - Return the data and metadata for the attribute.
/TRANSLATE:<table name>      - Translate output via values from <table name>.
/EVERY:<interval> [/REPEAT:<repeat count>] - Returns value every (X interval)
seconds, If /REPEAT specified the command is executed <repeat count> times.
/FORMAT:<format specifier>   - Keyword/XSL filename to process the XML results.
NOTE: Order of /TRANSLATE and /FORMAT switches influences the appearance of output.
Case1: If /TRANSLATE precedes /FORMAT, then translation of results will be followed by formatting.
Case2: If /TRANSLATE succeeds /FORMAT, then translation of the formatted results will be done.
