請教在IBM xSeries 345上安裝FreeBSD的問題 (No disks found - BBS

已用原廠的光碟config過RAID Controller (Server RAID 6i) 成RAID 5且已sync過
但安裝FreeBSD 5.21 (過程中有load ips driver module)
到了partition步驟時
卻出現下列message:

No disks found! Please verify that your disk controller is being
properly probed at boot time. See the Hardware Guide on the
Documentation menu for clues on diagnosing this type of problem.

請問一下 這該怎麼解決呢???
謝謝
