I'm having this, except that the LBA= is for various high numbers, 
and I'm on FreeBDS 6.3 which I installed onto the CF through a USB 
reader on a different device.

I want to know that too. Later that day:

I'm not seeing how to do that. I can't boot the Soekris box, so I 
can't run atacontrol there. How do I make the appropriate settings on 
the other box (the one that has the CF on a USB reader) so that they 
live through the bootup on the Soekris box?
