The Board Information Block in NVRAM contains various entries
that define operating parameters of the board hardware. Use the
162Bug command CNFG to change those parameters.
❏
Use the 162Bug command ENV to change configurable 162Bug
parameters in NVRAM.
The CNFG and ENV commands are both described in the Debugging
Package for Motorola 68K CISC CPUs User’s Manual, listed in Appendix
E, Related Documentation. Refer to that manual for general information
about their use and capabilities.
The following paragraphs present supplementary information on CNFG
and ENV that is specific to the 162Bug firmware, along with the
parameters that you can modify with the ENV command.
CNFG - Configure Board Information Block
Use this command to display and configure the Board Information Block
which resides within the NVRAM. The board information block contains
various elements that correspond to specific operational parameters of the
MVME162P2 board. (Note that although no memory mezzanine is
present on MVME1X2P2 series boards, the on-board memory is modeled
as such for backward compatibility.)
The board structure for the MVME162P2 is as follows:
