I have a Asus P3B-F JumperFreetm ATX Mother board, Western digital drive 40 gb,rj45,dial up card,sound card,video card...... Anyway the thing is I looked in the pc so I knew where the I/o header connections went worked fine till this. Installed new ram cause problems removed it. The thing is I put in differnt drives an the BIOS seems them some times an not others. Then when it tells me in the post if its there it says there is no primary master. I tried another ide cable an manual haveing it look at the drive in the bios.
