DS20, RAID && Boot floppies

Hi people!
        I'm trying (still) to install debian in a DS20 server. Now it can boot
from potato floppies (not woody), but it's not able to find any hard
disk. I think this is due to the DAC960 Raid controller. Any idea? I
think the solution is to boot with a kernel to suppport that controller,
but how can i modified the boot floppies?

        Thx in advanced
