Using the Flash Memory Card
Making the Flash Memory Card Image Bootable
Use the following series of commands to make the image (the file named new.image) bootable. Note
that, since the configuration register must be set to 0x2102, the config-register command is part of
the sequence.
Router# config terminal
Router(config)# no boot system
Router(config)# boot system flash slot0:new.image
Router(config)# config-register 0x2102
Router(config)# ^z
Router# copy running-config startup-config
Router# reload
When the system reloads it will boot the image new.image from the Flash memory card in Slot 0.
Note For complete details about the boot system flash command, refer to the next section,
“Enabling Booting from the Flash Memory Card.”
Enabling Booting from the Flash Memory Card
To enable booting from Flash memory, set configuration register bits 3, 2, 1, and 0 to a value between
2 and 15 in conjunction with the boot system flash [filename] configuration command.
Following are definitions of the various Flash memory-related boot commands:
boot system flash—Boots the first file in onboard Flash memory
boot system flash herfile—Boots the file named “herfile” on onboard Flash memory
boot system flash slot0:—Boots the first file on Flash memory card in the PCMCIA slot
boot system flash flash:hisfile —Boots the file named “hisfile” on onboard Flash memory
boot system flash slot0:myfile —Boots the file named “myfile” on the Flash memory card in the
PCMCIA slot
To enter configuration mode and specify a Flash memory filename in the PCMCIA slot from which
to boot, enter the configure terminal command at the enable prompt, as follows:
Router# configure terminal
Enter configuration commands, one per line. End with CTRL-Z.
Router(config)# boot system flash slot0:myfile
To disable Break and enable the boot system flash slot0: command, enter the config-register
command with the value shown in the following example:
Router(config)# config-reg 0x2102
To exit configuration mode, enter Cntl-Z as follows:
Router(config)# ^Z
Router#
To save the new configuration to memory, use the copy running-config startup-config command
as follows:
Router# copy running-config startup-config
