Upgrading Adaptec ARO1130 to 2100S

Hi, Sorry to double post. I posted this in Discussion centre & I think I should have posted it here as it’s a question.
I am trying to upgrade from Winnt4 to W2K but the ARO1130 raid/scsi isn’t supported in W2K & I haven’t found any 3rd party drivers. Adaptec say that I should buy the 2100S card, but didn’t actually say that it is compatible with the Supermicro M/bd “Super P6DBS” & all Supermicro will say is that the P6DBS is discontinued & they don’t know. Does anyone know if the 2100S card will work in the P6BDS m/bd, or have any other suggestions??
