FreeBSD unable to detect MegaRAID SAS 9240

Wed Nov 30 18:46:57 UTC 2011

Finally I got hint from http://forums.freebsd.org/showthread.php?t=27268
Rod posted a useful thread. I installed FreebSD on USB and added his
driver(for 9240), compiled the kernel.
While installing FreebSD 9.0 RC1, I went into Loader prompt where I
unloaded/ loaded kernel.
As of now, i can see da0(USB) and disk2(RAID HD) through lsdev but when I
went ahead its only displaying da0(the same USB).
I have responded to that post.
if anyone who can help me how to proceed?
