Rolling BIOS
The BIOS flash memory of this server is divided into two partitions: a primary (active)
partition from which the server boots, and a secondary partition to which BIOS updates
are diverted. When a BIOS update occurs, the existing BIOS image is preserved on the
primary partition and the system is automatically prompted to attempt to boot from the
new BIOS (on the secondary partition). If a boot failure occurs with the new BIOS, the
system will revert to the old BIOS on the other partition.
To manually select the BIOS boot partition:
1
Turn off the server, then disconnect the power cords and all other cables connected
to the server.
2
Follow the instructions in “Opening the server case” on page 38 .
Caution Moving the jumper while the power is on can damage your server.
Always turn off the server and unplug the power cords and all other
cables before changing the jumper.
