Simple Boot Loader Upgrades
With a simple boot loader system, see the following sections for either of the following
upgrade procedures, as desired. Only one of these procedures need to be performed for
an upgrade:
■ Updating the Simple Boot Loader
■ Migrating a Simple Boot Loader to a Dual-Stage Boot Loader
Updating the Simple Boot Loader
To update boot code on a simple boot loader system or to downgrade from a dual-stage
boot loader system, use the copy tftp image-bootrom command. The Privileged Exec
command has the following syntax:
copy tftp://ip/{filepath/}bootcode-filename image-bootrom
After the image is downloaded and installed, the CLI prompt is released.
Migrating a Simple Boot Loader to a Dual-Stage Boot Loader
The dual-stage boot loader can be loaded along with the simple boot loader. When both
types of boot loaders are found on the system, the switch installs the dual-stage boot
loader and converts the raw image to an industry standard format. The installation
process is:
1 Install the dual-stage boot loader system using the copy bootrom-package
command. The Privileged Exec command has the following syntax:
copy tftp://ip/filepath/bootpkg-filename bootrom-package
Syntax Description ip Specifies the IP address of the TFTP server.
filepath (Optional) Specifies the directory path to the
simple boot loader.
bootcode-
filename
Specifies the name of the boot loader being
downloaded.
