Dell PowerEdge R920 w/ Perc H730P

[RANDOLPH, DONALD L]

Just tried an install using the FreeBSD-10.1-PRERELEASE-amd64-20140902-r270981-memstick.img.
During the extraction process I get:

kernel: NMI ISA 30, EISA ff
mfi0: Failed to get command

Then a repeating message of:
mfi0: COMMAND 0xfffffe0002100af8 TIMEOUT AFTER XXX SECONDS

I did a load mrsas at the loader... and it told me it couldn't find it.  
I also did a set hw.mfi.mrsas_enable=1

During the install process it still detects the raid as mfi0 and not da0.

Am I doing something wrong?  Is there a different process or files I should be using?

Thanks

Don
