Download the supported FCA BIOS update, available on http://www.hp.com/support/

downloads, to a virtual floppy.

For instructions on creating and using a virtual floppy, see the HP Integrated Lights-Out

User Guide.

2. Unzip the file.

3. Follow the instructions in the readme file to load the NVRAM configuration onto each

FCA.

• If you have a blade server other than a ProLiant blade server:

Download the supported FCA BIOS update, available on http://www.hp.com/support/

downloads.

2. Unzip the file.

3. Follow the instructions in the readme file to load the NVRAM configuration onto each

FCA.
