When the entire boot field equals a value between 0-0-1-0 and
1-1-1-1, the router loads the system image specified by boot sys-
tem commands in the startup configuration file. When the startup
configuration file does not contain boot system commands, th
router loads a default system image stored on a network server.
When loading a default system image from a network server, the
router uses the configuration register settings to determine the default
system image filename for booting from a network server. The router
forms the default boot filename by starting with the word cisco and
then appending the octal equivalent of the boot field number in th
configuration register, followed by a hyphen (-) and the processor type
name (cisconn-cpu). See the appropriate hardware installation guide
for details on the configuration register and default filename.
Setting the Boot Field
You must correctly set the configuration register boot field to ensure
that your router loads the operating system image as you intend. To set
the boot field:
1. Obtain the current configuration register setting. This setting is
hexadecimal value.
2. Modify the current configuration register setting to reflect the way
you want to load a system image. To do so, change the least sig-
nificant hexadecimal digit to:
0 to load the system image manually using the
boot
command in
ROM monitor mode.
1 to load the system image from boot ROMs.
2 through F to load the system image from
boot
system com-
mands in the startup configuration file or from a default system
image stored on a network server.
For example, if the current configuration register setting is 0x101 and
you want to load a system image from boot system commands in the
startup configuration file, you would change the configuration register
setting to 0x102.
1. Reboot the router to make your changes to the configuration reg-
ister take effect.
