Installation - no disks detected

[Prateek Sharma]

Hello,
 	I am trying to install FreeBSD-8.1 on a server with the LSI SAS 9200 disk controller card. 
Before the partitioning step the installer says "disks not found.".

However, just after freebsd boots , i get the diagnostic message saying something like:
"Drive C: is disk ad0
Drive D: is disk ad1
.. " 
So are my disks getting detected or not? Does anyone know if the card is supported by FreeBSD?
Is there any way i can get this to work?

Thanks !
