Chapter 33 Working with System Software Images
This example shows the autoboot configuration:
Console> (enable) show boot
BOOT variable = bootflash:cat4000.5-5-8.bin,1;
CONFIG_FILE variable = bootflash:switch.cfg
Configuration register is 0x102
ignore-config:disabled
auto-config:non-recurring
console baud:9600
boot:image specified by the boot system commands
Console > (enable)
Step 6 If the last line in the output of the show boot command does not say
boot:image specified by the boot system commands
then enter the set boot config-register command to set the boot configuration.
This example shows how to set the boot configuration:
Console> (enable) set boot config-register boot system
Configuration register is 0x102
ignore-config:disabled
auto-config:non-recurring
console baud:9600
boot:image specified by the boot system commands
Console> (enable)
Enter the set boot system flash command to prepend the promupgrade image to the boot string.
Step 7
Note
This example shows how to prepend the promupgrade image to the boot string:
Console> (enable) set boot system flash bootflash:cat4000-promupgrade.6-1-4.bin prepend
BOOT variable = bootflash:cat4000-promupgrade.6-1-4.bin,1;bootflash:cat4000.5-5-8.bin,1;
Reset the switch to boot the promupgrade program.
Step 8
No intervention is necessary to complete the upgrade. Do not interrupt the boot process by performing
Caution
a reset, power cycle, or OIR of the supervisor engine for at least 5 minutes. If the process is not allowed
to complete, you might damage the switch and have to return it to Cisco for repair.
Upgrading the ROMMON takes up to 5 minutes because the switch boots the promupgrade image. This
program erases the current ROMMON from the Flash memory and installs the new one. After you install
the new ROMMON, the system resets again and boots the next image in the BOOT string. If you
configure the BOOT string as described in Step 7
that the switch was originally configured to boot.

Make sure that you enter the prepend keyword with the set boot system flash command. The
switch always boots the first image in the boot string, and you want the promupgrade image to
boot first.
A Telnet session is disconnected when you reset the switch; you will lose connectivity to the
switch.
