ROM Monitor Commands
• boot or b—Boots an image. The boot command with no arguments boots the first image in boot
Flash memory. You can include an argument, filename, to specify a file to be booted over the network
using the Trivial File Transfer Protocol (TFTP). The local device (see the description of b device
following) can be specified by entering the device specifier (devid). If the specified device name is
not recognized by the ROM monitor, the system attempts to boot the image (imagename) from a
network TFTP server. Do not insert a space between devid and imagename. Options to the boot
command are -x, load image but do not execute, and -v, verbose. The form of the boot command
follows:
boot [-xv] [devid] [imagename]
b—Boots the default system software from ROM.
b filename [host]—Boots using a network TFTP server. When a host is specified, either by name or
b flash:—Boots the first file in Flash memory.
b device:—Boots the first file found in the Flash memory device. The Flash memory device
specified can be either flash:, to boot the Cisco IOS software, or bootflash:, to boot the boot image
in Flash memory.
b device:name—An extension of the above command, allows you to specify a particular filename in
the Flash memory bank.
confreg [hexnum]—Executing the confreg command with the argument hexnum changes the virtual
•
configuration register to match the hex number specified. Without the argument, confreg dumps the
contents of the virtual configuration register in English and allows you to alter the contents. You are
prompted to change or keep the information held in each bit of the virtual configuration register. In
either case, the new virtual configuration register value is written into NVRAM and does not take
effect until you reset or power cycle the gateway.
The configuration register resides in NVRAM. The configuration register is identical in operation
to other Cisco gateways. Enter confreg for the menu-driven system, or enter the new value of the
register in hexadecimal.
