I have a 250gb maxtor ide harddrive from my old system connected to a promise ultra 100 tx2. When I have the connector pin set to either master or cable select the drive is recognized in the bios but my system fails to boot up and i just get a blank screen. But when i remove the pin totally the system boots up and recognizes the drive in the bios but after xp starts up the drive is nowhere to be seen.I have the dell dimension 9100.I already have a dvd rom and dvd recorder connected to the motherboard ide cable.
