Added: trunk/util/nvramtool/nvramtool.8 Removed: trunk/util/nvramtool/nvramtool.1 Modified: trunk/util/nvramtool/Makefile Log: Move the nvramtool manpage to section 8 (as it's only really usable as root), as we've done with the superiotool and flashrom manpages, too (trivial).

If redirected to a file, -the layout information may be used as input for the -.B "'-y LAYOUT_FILE'" -option (see below). -.TP -.B "-b OUTPUT_FILE" -Write the contents of CMOS memory to the binary file -.B "OUTPUT_FILE." -The first 14 bytes of -.B "OUTPUT_FILE" -do not contain actual CMOS data, and are always written as zeros. This is -because the first 14 bytes of the CMOS area do not contain CMOS memory. These -bytes are involved with the functioning of the real time clock. -.TP -.B "-B INPUT_FILE" -Read binary data from -.B "INPUT_FILE" -and write the data to CMOS memory. The first 14 bytes of -.B "INPUT_FILE" -are skipped and data is written to CMOS starting at the 15th byte of the CMOS -area. This is because the first 14 bytes of the CMOS area do not contain CMOS -memory. These bytes are involved with the functioning of the real time clock. -.TP -.B "-x" -Show a hex dump of all CMOS data. The first 14 bytes of the dump do not -contain actual CMOS data, and are always shown as zeros. This is because the -first 14 bytes of the CMOS area do not contain CMOS memory. These bytes are -involved with the functioning of the real time clock. -.TP -.B "-X DUMPFILE" -Read binary data from -.B "DUMPFILE" -(presumably a CMOS dumpfile created using the -.B "-b OUTPUT_FILE" -option) and show a hex dump of the data. -.TP -.B "-v" -Show version information for this program. -.TP -.B "-h" -Show a help message for this program. -.SH "OPTIONS" -In all cases above, -.B "[OPTS]" -evaluates to the following: - -.B " [-y LAYOUT_FILE | -t]" - -The -.B "'-y LAYOUT_FILE'" -option tells nvramtool to obtain CMOS layout information from the contents of -.B "LAYOUT_FILE." -Likewise, the -.B "'-t'" -option tells nvramtool to obtain CMOS layout information from the CMOS option -table (contained within the coreboot table). If neither option is -specified, the CMOS option table is used by default. -.B "LAYOUT_FILE" -follows the format of the -.B "cmos.layout" -files provided by coreboot. - -If the coreboot installed on your system was built without specifying -.B "HAVE_OPTION_TABLE," -then the coreboot table will not contain a CMOS option table. In this case, -the -.B "'-y LAYOUT_FILE'" -option must be used. - -These two options are silently ignored when used in combination with other -options (such as -.B "-h," -for instance) for which they are not applicable. -.SH FILE FORMAT -For the -.B "-p" -option, -.B "INPUT_FILE" -must consist of a sequence of lines such that each line is either a blank -line, a comment, or an assignment. A blank line consists only of zero or -more whitespace characters (spaces and tabs). A comment is constructed as -follows: - -.B " [ws]#[text]" - -Here, -.B "[ws]" -indicates optional whitespace characters and -.B "[text]" -indicates optional text.
