CNFG and ENV Commands
6
The value or identifier to the left of the equal sign is displayed as left-
justified character (ASCII) strings padded with space characters and
quotes (“) are displayed to indicate the size of the string. Values that are
not in quotes are considered data strings and data strings are right-justified.
The data strings are padded with zeroes if the length is not met. It is
important to note that the MCP750 has no local SCSI bus controller, hence,
the Local SCSI Identifier parameter is ignored by the PPCBug.
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 MCP750 Single Board Computer Programmer’s
Reference Guide, listed in
Appendix C, Related Documentation
, for the
actual location and other information about the Board Information Block.
Refer also 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 Non-Volatile RAM (NVRAM).
Refer to the PPCBug Firmware Package User's Manual for a description
of the use of ENV.
