ROM Monitor

This will change the virtual configuration register to the value specified. The

value is always interpreted as hexadecimal. Entering confreg without an

argument displays the contents of the virtual configuration register and a prompt

to alter the contents by describing the meaning of each bit.

Whether or not an argument is provided, the new virtual configuration register

value is written into NVRAM, but it does not take effect until you reset or

power-cycle the router.
