USING NVEDIT TO MODIFY
NVRAM
C.1 NVRAM Edit Commands
This section discusses the use of NVRAM. The NVRAM is used
to set the resolution in the Video-Mode and Video-Timing
methods. To edit the NVRAM, begin nvedit at the ok prompt.
There are several commands that you must use to edit the
variables in NVRAM:
<Backspace>
deletes the character preceding the cursor
<Ctrl-l>
lists NVRAM current values
<Ctrl-p>
moves to the previous line
<Ctrl-n>
moves to the next line
<Ctrl-b>
moves to the previous character
<Ctrl-f>
moves to the next character
<Ctrl-u>
deletes to the beginning of the line
<Ctrl-k>
joins the current and next line
<Ctrl-u><Ctrl-k>
deletes the current line
<Ctrl-c>
exits the NVRAM editor (back to the ok
prompt)
The changes will only take effect if they are stored using the
nvstore command entered at the ok prompt. Once the
changes are stored, the NVRAM must be enabled before the
system will execute it. This is done by setting the environment
variable use-nvramrc? to true. Please reset the system to
make the changes effective.
