Appendix B NVRAMRC Editor and NVEDIT Keystroke Commands

This section provides useful nvramrc editor and nvedit keystroke commands.

An nvramrc script contains a series of OBP commands that are executed during the boot sequence. The procedures in this guide assume that this script is empty. If your nvramrc script contains data, add the entries to the end of the script. To edit an nvramrc script or merge new lines in an nvramrc script, use nvramrc editor and nvedit keystroke commands.

Table B-1 and Table B-2 list useful nvramrc editor and nvedit keystroke commands. For an entire list of nvramrc editor and nvedit keystroke commands, see OpenBoot 3.x Command Reference Manual.
