Windows setup can not find hard drive

Hi there,
I am reinstalling windows 2003 server on intel D865perl machine with promise Fast Trak S150 S*4 SCSI raid 5, however the setup can not detect hard drive, so I did F6 then press S to have computer copy driver from A drive which I copied from intel website. For some reason, it seems not able to retrive driver from A drive even I enabled SCSI in bois. I know A drive does work. Would that be a misconfiguration in bois, wrong driver, or anything else? Any help would be appreciated.
