debian 7 on DL360 g8 with b320i raid controller - can't find disc

hey,

I'm trying to install debian 7 on my HP Proliant DL360e gen8 server with an smart array b320i Raid Controller. when debian-installer comes to the disc detection it says "cannot find any disc". I tried to select the hpsa driver manually - same result, and I tried this suggested solution:
http://lists.debian.org/debian-user/2012/10/msg00088.html

doesn't change anything..

does anybody have any other suggested solution?
