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.

The Board Information Block is factory-configured before shipment. There is no need to modify block parameters unless the NVRAM is corrupted.

Refer to the PrPMC800/800ET Processor PMC Module Programmer’s Reference Guide for the actual location and other information about the Board Information Block.

Refer to the PPCBug Firmware Package User's Manual for a description of CNFG and examples.

ENV – Set Environment

Use the ENV command to view and/or configure interactively all PPCBug operational parameters that are kept in NVRAM.

Refer to the PPCBug Firmware Package User’s Manual for a description of the use of ENV. Additional information on registers are contained in your PrPMC800/800ET Processor PMC Module Programmer’s Reference Guide.

Listed and described below are the parameters that you can configure using ENV. The default values shown were those in effect when this publication went to print.

Configuring the PPCBug Parameters

The parameters that can be configured using ENV are:

Bug or System environment [B/S] = B?

BBug is the mode where no system type of support is displayed. However, system-related items are still available. (Default)

SSystem is the standard mode of operation, and is the default mode if NVRAM should fail. System mode is defined in the PPCBug Firmware Package User’s Manual.

Field Service Menu Enable [Y/N] = N?

YDisplay the field service menu.

NDo not display the field service menu. (Default)
