Modifying the Environment

Overview

You can use the factory-installed debug monitor, PPCBug, to modify
certain parameters contained in the MVME2100 Non-Volatile RAM
(NVRAM), also known as Battery Backed-up RAM (BBRAM).

❏

The Board Information Block in NVRAM contains various
elements concerning operating parameters of the hardware. Use the
PPCBug command CNFG to change those parameters.

❏

Use the PPCBug command ENV to change configurable PPCBug
parameters in NVRAM.

The CNFG and ENV commands are both described in the PPCBug
Firmware Package User’s Manual. Refer to that manual for general
information about their use and capabilities.

The following paragraphs present additional information about CNFG and
ENV. Some paragraphs may provide examples of MVME2100
information, but the majority of the information is specific to the generic
PPCBug commands and parameters being discussed. Also included, are
the parameters that can be configured with the ENV command.
