Booting from the Cisco IOS Software Image

After locating a valid Cisco IOS software image, you can boot from that image manually by issuing the appropriate ROM monitor mode boot commands from the list in Table 3-13.

Table 3-13 ROM Monitor Boot Commands

Command	Description

boot	(No argument.) Boots the default image found in the
	onboard Flash memory SIMM. The image is loaded
	into the SIMM at the factory.

boot flash	Attempts to boot the router using the first file found
	in the Flash memory card inserted in slot 0 of the RP.

boot slot0: filename	Boots the router using the specified file from the
	Flash memory card in slot 0 of the RP.

boot slot1: filename	Boots the router using the specified file from the
	Flash memory card in slot 1 of the RP.

boot bootflash: filename	Boots the router using the specified file from the
	onboard Flash memory SIMM (NVRAM) on the RP.

boot tftp: filename	Boots the router using the specified file from a host
[host]	TFTP server in the network.

Ensure that the Flash memory card inserted in PCMCIA slot 0 contains a valid Cisco IOS software image. Otherwise, the system will boot an invalid image from the Flash memory card. To examine the contents of a Flash memory card, enter the dir slotn: command.

If you did not change the contents of the software configuration register, the factory default setting of 0x0102 in the software configuration register causes the system to boot Cisco IOS software from a Flash memory card inserted in PCMCIA slot 0 the next time you boot the router.
