Booting from a Flash Disk

This section describes the commands used to boot from a Flash disk. Flash disks are accessed using disk0: or disk1:, depending on the card slot location, instead of slot0: or slot1:, which is used with linear Flash memory cards.

Note A boot image that supports the ATA Flash disk file system must reside in bootflash.

To enable booting from a Flash disk, set the register bits to 0x2102 and add the boot system command, as follows:

Router#configure terminal

Enter configuration commands, one per line. End with CTRL-Z.

Router(config)#config-reg 0x2102

Router(config)#boot system disk0:c12kprp-p-mz.120-22.S

Router(config)#^Z

Router#copy running-config startup-config

The boot system command may require a file name when applied to a Flash disk. The format is described in Table 14.

Table 14	Boot System Command Format
Router(config)#boot		system	disk0:filename1	Boots the named file from the Flash disk in slot 0.
Router(config)#boot		system	disk1:filename1	Boots the named file from the Flash disk in slot 1.

1.Entering a filename is optional. If a filename is not specified, the system attempts to boot the first file located on the Flash disk.
