The 187Bug debugger commands are summarized in Table 5-1. The
command syntax is shown using the symbols explained earlier in
this chapter. The CNFG and ENV commands are explained in
Appendix A. Controllers, devices, and their LUNs are listed in
Appendix B or Appendix C. All other command details are
explained in the MVME187Bug Debugging Package User's Manual.This Appendix Covers

Configuring the Board Information Block
CNFG [;[I][M]]
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 MVME187 RISC Single Board
Computer User's Manual for the actual location.
The information block contains various elements detailing specific
operation parameters of the hardware. The MVME187 RISC Single
Board Computer User's Manual 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. 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 rightjustified. 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. A 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 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.
