Support for MegaRAID SAS on FreeBSD

Sat Nov 5 17:28:51 UTC 2011

I am facing issue while installing FreeBSD 9.1 RC1 on Dell PowerEdge Server
with MegaRAID SAS 9240 driver.
It is unable to detect the controller.Any idea how to troubleshoot?
I can see that it has mfi.1 driver loaded.(I am not sure if thats mfi/mps).
Do I need to rebuilt the kernel with this new driver.If yes, what steps I
need to follow.
I can see that LSI does provide the new 3.98_FreeBSD_x86_and_x64_drivers
but uncertain if that would work.
