Configure and Environment Commands

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 zeroes 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.The following warning message:

(WARNING: Board Information Block Checksum Error)

is also displayed in the event of a checksum failure.

Using the I option initializes the unused area of the board information block to zero.

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 “YÓ 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. Some of these parameters are set up by the factory, and correct board operation relies upon these parameters.

Once modification/update is complete, you can now display the current contents as described earlier.
