Bootloading Problems on E250

I have a Sun E250 that was decommissioned over the summer (it had  
been running Solaris 9) that I want to put back into service running  
FreeBSD 6. I've had no end of problems yet.
Firstly, I'd tried booting from a 6-RELEASE CD. That doesn't work.  
The next approach I took was to use an old Ultra60 to build the  
latest STABLE code onto a hard drive which I can pop into my E250.  
Here's what happens when I stick the drive into the E250 and try to  
boot from it:

Clearly the E250 is not as "fully supported" as the hardware docs  
indicate. Where do I begin trying to fix this problem?
