Very good, this is exactly what I wanted to setup.

The main board is a Supermicro P4SCT+ which has a 'serial console'
option.

This can be set to relinquish the console control to the OS
when it boots.

This mode shows the raid card's bios messages at boot
so you can control it if needed, then prints the output of
the fbsd loader when it starts -perfect.

tnx
