Using the ROM Monitor
This appendix describes the ROM monitor (also called the bootstrap program), which is the firmware
that runs when you power on or restart the Cisco VG202 and Cisco VG204 voice gateways (VG). During
normal operation, the ROM monitor helps to initialize the processor hardware and boot the operating
system software. You can also use the ROM monitor to help you isolate or rule out hardware problems
that you encounter while installing your voice gateway.
This appendix contains the following sections:
• Entering the ROM Monitor Mode, page A-1
• ROM Monitor Commands, page A-2
• Command Descriptions, page A-3
• Configuration Register, page A-4

rebooted.
