A hardware boot ROM upgrade might be required to upgrade the Catalyst OS (CatOS) on a Supervisor Engine I or IA.
The Supervisor Engine I or IA requires a minimum boot ROM of 5.2(1) for software release 5.4(1) and later 5.x(x) releases. The minimum boot ROM required for software releases 6.x(x) and later is 5.2(1).
To verify the current boot ROM version, issue the show version command.
This is the sample command output:

To upgrade the boot ROM on a Catalyst 6000 Supervisor Engine I or IA, choose from one of these options:
For supervisor engines with a Multilayer Switch Feature Card (MSFC), due to the location of the boot ROM, upgrading the boot ROM could damage your supervisor engine. This hardware configuration is not field upgradeable.
For supervisor engines with an MSFC2 or no Policy Feature Card (PFC), the boot ROM upgrade can be done in the field.
The boot ROM upgrade kit part number is WS-X6K-BOOT=.
