Modification is permitted by using the M option of the command. At the end of the modification session, you are prompted for the update to Non-Volatile RAM (NVRAM). A Y response must be made for the update to occur; any other response terminates the update (disregards all changes). The update also recalculates the checksum. Be cautious when modifying parameters. These parameters are initialized by the factory, and correct board operation relies upon these parameters.Once modification and update is complete, you can now display the current contents as described earlier.
Setting Environment to Bug/Operating System
The Environment (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/powerup 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.
