CSA is a proprietary bus connected to the MCH.

It´s primary purpose at this time is to provide bandwidth to run a GE 
without having to go through the other busses.

I got a new BIOS from supermicro where the _PRT entry exists, it´s located
at http://helenius.fi/p4sctnew.asl but now I get no error messages but 
the system still does not work. (vmstat -i shows no interrupts for em0)
Previously I got watchdog timeout errors.

I also put http://helenius.fi/sct.mptable and 
http://helenius.fi/sct.pciconf available.
