NAME

dmpnvrcfg − dump NVRAM configuration information

SYNOPSIS

/sbin/dmpnvrcfg

DESCRIPTION

dmpnvrcfg displays information from the configuration slice of the NVRAM device on stdout The information will be displayed regardless of the validity of the NVRAM checksum.  Byte values of 0x00 through 0x1f inclusive, and 0x7f through 0xff inclusive, will be displayed as ’?’.  ASCII fields are displayed with leading and trailing ’ " ’ characters.  Hexedecimal fields are preceded by ’0x’.  All other fields are decimal.  Each display field is preceded by a field description followed by an ’ = ’. 

If the checksum is invalid, a warning message giving both the computed and stored checksum value in decimal is displayed on stderr.  The absence of this message means that the checksum is valid.
