3.5.2 BIOS Select
The CB1051 has two firmware hubs which makes it possible to store different BIOS versions in each hub.
If you then want to change from one BIOS to the other the "BIOS Select" jumper must be used. In the
default configuration this jumper is open which means that BIOS 1 is active. To activate BIOS 2 the
jumper must be closed. Of course, the board must be switched off before changing this or any other
jumper setting.
C
AUTION
The second firmware hub can also be used as an option ROM. If this is the case closing the "BIOS
Select" jumper will render the board unable to start.
