CONFIGURE AND ENVIRONMENT COMMANDS
Configure Board Information Block
CNFG [;[M][I]]
This command is used to display and configure the board information block. This block is resident within the Non-Volatile RAM (NVRAM). Refer to the MVME197LE Single Board Computer User’s Manual for the actual location. The board information block contains various elements detailing specific operation parameters of the hardware. The MVME197LE Single Board Computer User’s Manual also describes the elements within the board information block, and lists the size and logical offset of each element. The CNFG command does not describe the elements and their use. The board information block contents are checksummed for validation purposes. This checksum is the last element of the block.
Example: To display the current contents of the board information block.

Note that the parameters that are quoted are left-justified character (ASCII) strings padded with space characters, and the quotes (“) are displayed to indicate the size of the string. Parameters that are not quoted are considered data strings, and data strings are right-justified. The data strings are padded with zeros if the length is not met.
In the event of corruption of the board information block, the command displays a question mark “?” for nondisplayable characters. A warning message (WARNING: Board Information Block Checksum Error) is also displayed in the event of a checksum failure.
Using the option initializes the unused area of the board information block to zero.
