NAME

nvram − display or set values of NVRAM variables

SYNOPSIS

/etc/nvram [name=value]

DESCRIPTION

nvram without any parameters displays the current values set in the system non-volatile memory.  Each line displayed contains an NVRAM variable name, followed by an equals sign, followed by a string.  For example, typing nvram might display

baud=9600
etheraddr=00-00-7a-80-00-01
netaddr=192.9.200.160
hostname=ca
screen_font=2
path=bfs()
screen_back=403050
bootmode=a
screen_fore=cc8800
rootdev=scsi(0,5,0)
swapdev=scsi(0,5,1)
bootfile=scsi(0,5,8)sash
dumpdev=scsi(0,5,1)
console=graphics

nvram can also be used to remove an NVRAM variable, add an NVRAM variable, or remove an NVRAM variable.  Typing

nvram name=

removes name from the list of name/value pairs stored. 

Typing

nvram name=value

where name is an existing NVRAM variable name will change its contents to the string typed.  If the name does not already exist, then it is added to the list of name/value pairs. 

The value part can be any arbitrary collection of charaters. 

WARNING

Only the super-user is allowed to remove or alter NVRAM values.
