Configure 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
MVME166 Single Board Computer User’s Manual for the actual location. The
information block contains various elements detailing specific operation
parameters of the hardware. The MVME166 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.
