Program VPD SROM (Y/N)? n
If the Program VPD SROM (Y/N)? question is answered affirmatively, the edits are written
to the VPD SROM. A new checksum is also calculated and written. Answering negatively
prevents any change to the existing SROM contents.
A.3 Global Environment Variables (GEVs)
Global Environment Variables (GEVs) are used to store nearly any value for later retrieval, even
after loss of power or hardware reset. Each value saved needs a unique label, the label being
defined at the same time as the value. Global Environment Variables in MOTLoad are based
loosely on the GEV concept presented in the PReP Specification. However, MOTLoad does not
claim compliance to that specification.
GEVs are typically stored in NVRAM. MOTLoad requires 8K bytes at the top end of NVRAM. The
amount of space set aside in the NVRAM for storage of GEVs is 3592 bytes.
Note: in safe-start mode, MOTLoad ignores all GEVs.
A.3.1 Initializing the GEV Storage Area
The gevInit command is used to initialize the GEV area of the NVRAM device. Execution of this
command deletes all currently defined GEVs, and prepares the GEV area for its first variable.
This command should be used with caution, as re-entry of all removed GEVs (as with gevEdit)
can be time-consuming.
