ENV - Set Environment

Use the ENV command to view and/or configure interactively all PPCBug operational parameters that are kept in Non-Volatile RAM (NVRAM).

Refer to the PPCBug Firmware Package User’s Manual (PPCBUGA1/UM) for a description of the use of ENV.

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)

Probe System for Supported I/O Controllers [Y/N] = Y?

YAccesses will be made to the appropriate system buses (e.g., VMEbus, local MPU bus) to determine the presence of supported controllers. (Default)

NAccesses will not be made to the VMEbus to determine the presence of supported controllers.
