Q: When I start up my machine, I get a message that says:
'mfg-options' environment variable invalid
How do I fix this?


A:
Summary:
1) Get to the OK prompt.
2) Set the mfg-options variable to the appropriate value.
3) Reset the machine.


Detailed:
1) Get to the OK prompt.
If you are still at the OBP level, hit STOP+A to get to the OK prompt. If you are already in the OS, bring it down to the OK prompt by typing:
init 0

2) Set the mfg-options variable to the appropriate value. I have only encountered this error on workgroup servers, such as an E250. If you encounter it on another type of machine, the value will be different.

At the OK prompt, type:
setenv mfg-options server

3) Set defaults and check that the value worked.
set-defaults

The machine should respond with:
Setting NVRAM parameters to default values.
Platform is configured as a Server

3) Reset the machine.
Type:
reset-all

You should not see the message again. If you get the repeatedly after this, it may be an indication that the battery in your NVRAM chip going bad and the NVRAM chip should be replaced.
