10. PCI: Primary VGA device becomes that VGA device which is found on the highest PCI
bus. If more than one VGA device is found on that bus, the VGA device with the highest
device number becomes primary VGA
Level 2 Cache
The processors cache can be disabled here. Disabling the cache will slow down code processing
dramatically, so this is merely a feature for testing and debugging.
USB legacy support
The current version of Embedded BIOS does not support USB devices. This setting is not
alterable at the moment (future option).
BIOS Standard I/O Port
Operation of the CC5-RAVE as a desktop PC requires monitor and keyboard to be attached
(CC6-ACID needed for KBD). As an alternative, I/O might be redirected to the ‘COM1' or ‘COM2'
serial interfaces (also requires CC6-ACID super I/O board). Attach a VT100 like ASCII terminal (or
PC equipped with a terminal emulation program) to the selected port. Standard I/O redirection
will be aborted on pressing any key on the PS/2 keyboard (the CMOS parameter itself is not
changed).
BIOS Setup I/O Port
In a likewise manner as the standard I/O redirection, the BIOS setup procedure might be
redirected to the ‘COM1' or ‘COM2' serial interfaces. Setup I/O redirection will be aborted on
pressing any key on the PS/2 keyboard (the CMOS parameter itself remains unchanged).
BIOS Debugger I/O Port
In a likewise manner as the standard I/O redirection, the debugger operation might be
redirected to the ‘COM1' or ‘COM2' serial interfaces. The BIOS is provided with an integrated
debugger. The ‘VGA/KEYB’ mode requires the graphics hardware to work properly, and - more
important - overwrites screen contents generated by the application which has to be debugged.
Debugger I/O redirection cannot be aborted on pressing any key on the PS/2 keyboard
