NAME

     ethcheck -- check the integrity of Broadcom Ethernet devices' firmware.

SYNOPSIS

     ethcheck --integrity-check [-b filename]
     ethcheck --show-hashes [-b filename]
     ethcheck --save -b filename
     ethcheck --cleanup -b filename
     ethcheck --version
     ethcheck --help

DESCRIPTION

     Ethcheck is an application-layer tool to check the integrity of Broadcom Ethernet devices' firmware.

     The following commands can be used with ethcheck:

     --integrity-check attempt to automatically determine which firmware you are running, integrity check against the appropriate file, and report
     the check result. It requires root privileges.

     --integrity-check -b filename integrity check the firmware image, and report the check result.

     --show-hashes print the hashes for the current system's Ethernet devices' firmware to stdout. It requires root privileges.

     --show-hashes -b filename print the hashes for the given firmware image to stdout.

     --save -b filename save this Ethernet device(s)'s firmware in file. It requires root privileges. File name(s) will begin with specificed
     filename and be selected according to device ID(s), machine model name, and firmware's version(s). E.g. filename-eth0-0x14e4-0x1686.nvram.bin

     --cleanup -b filename zero any privacy-sensitive data (such as MAC address), enabling the file to be shared for analysis.

     --version print out ethcheck version number.

     --help display a short help.

NAME

       nvram - manipulate firmware NVRAM variables

SYNOPSIS

       nvram [ -p ] [ -f filename ] [ -d name ] [ -c ] [ name [= value ]] ...

DESCRIPTION

       The  nvram command allows manipulation of firmware NVRAM variables.  It can be used to get or set a variable.  It can also be used to print
       all of the variables or set a list of variables from a file.  Changes to NVRAM variables are only saved by clean restart or shutdown.

       In principle, name can be any string.  In practice, not all strings will be accepted.  New World  machines  can	create	new  variables	as
       desired.  Some variables require administrator privilege to get or set.

       The  given  value  must match the data type required for name.  Binary data can be set using the %xx notation, where xx is the hex value of
       the byte.  The type for new variables is always binary data.

OPTIONS

       -d name
	      Deletes the named firmware variable.

       -f filename
	      Set firmware variables from a text file.	The file must be a list of "name value" statements.  The first space on each line is taken
	      to be the separator between "name" and "value".  If the last character of a line is , the value extends to the next line.

       -x     Use  XML	format	for reading and writing variables.  This option must be used before the -p or -f options, since arguments are pro-
	      cessed in order.

       -c     Delete all of the firmware variables.

       -p     Print all of the firmware variables.

EXAMPLES

	      example% nvram boot-args="-s rd=*hd:10"

       Set the boot-args variable to "-s rd=*hd:10".  This would specify single user mode with the root device in hard drive partition 10.

	      example% nvram my-variable="String One%00String Two%00%00"

       Create a new variable, my-variable, containing a list of two C-strings that is terminated by a NUL.

	      example% nvram -d my-variable

       Deletes the variable named my-variable.
