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
.
