Setting Environment to Bug/Operating System

ENV [;[D]]

The ENV command allows you to interactively view and configure all Bug operational parameters that are kept in Battery Backed Up RAM (BBRAM), also known as Non-Volatile RAM (NVRAM). The operational parameters are saved in NVRAM and used whenever power is lost.

Any time the Bug uses a parameter from NVRAM, the NVRAM contents are first tested by checksum to insure the integrity of the NVRAM contents. In the instance of BBRAM checksum failure, certain default values are assumed as stated below.

The bug operational parameters (which are kept in NVRAM) are not initialized automatically on power-up/warm reset. It is up to the Bug user to invoke the ENV command. Once the ENV command is invoked and executed without error, Bug default and/or user modified parameters are loaded into NVRAM along with checksum data. The operational parameters that have been modified will not be in effect until a reset/power-up condition.

If the ENV command is invoked with no options on the command line, you are prompted to configure all operational parameters. If the ENV command is invoked with the option D, ROM defaults will be loaded into NVRAM.
