Custom Configuration Setup Screen
The system’s hardware-specific features are configured with the Custom Setup Screen. All
features are straightforward except for the Redirect Debugger I/O option, which is an extra
embedded feature that allows the user to select whether the Integrated BIOS Debugger should
use standard keyboard and video or RS232 console redirection for interaction with the user. If
no video is available, the debugger is always redirected.
Processor Throttle Mode
This option allows to reduce considerably the CPUs power consumption, useful for low power
applications, or when high ambient temperatures can occur. If the full processor performance
is not needed, the CPU can be throttled back either on a fixed or temperature controlled (future
option) base, to 12.5/25/37.5/50/62.5/75/87.5%. Switch the throttle mode off if the full CPU
performance is required.
Scan PCI Buses
On POST, the BIOS scans the PCI bus for attached devices. If this option is set to ‘ALL’, any PCI
device is detected, also those components which are behind several PCI to PCI bridges. Setting
the scan to ‘0 only’ limits the enumerating procedure to the local CC5-RAVE chipset and speeds
up the POST process. A value of 0-1 additionally includes scanning of local devices as the
Ethernet controller and the PCI bridge. 0-2 would include all those devices outside the CC5-
