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:filename
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.
Boots the named file from the Flash disk in slot 0.
Router(config)#boot system disk1:filename
1
Boots the named file from the Flash disk in slot 1.
