Available main memory starts at 0x10000, size 40896KB IO (packet) memory size: 5 percent of main memory. Exiting the ROM Monitor You must set the configuration register to a value from 0x2 to 0xF for the voice gateway to boot a Cisco IOS image from flash memory upon startup or reloading. The following example shows how to reset the configuration register and cause the voice gateway to boot a Cisco IOS image stored in flash memory: rommon 1 > confreg 0x2101 You must reset or power cycle for new config to take effect: rommon 2 > boot The voice gateway will boot the Cisco IOS image in flash memory. The configuration register will change to 0x2101 the next time the voice gateway is reset or power cycled. Cisco VG202 and Cisco VG204 Voice Gateways Software Configuration Guide A-8 OL-16191-01
