I have a HP small pc that only has room for a slimline cdrom. It doesn't have a secondary ide connection, but it has a 50 pin connector on the mother board that says cd rom. I have a slimline cd rom to put in it that has a 40 pin connector, power supply connector, and audio connector, but no jump jacks to master or slave. I tried to put on primary drive with hdrive, but it could not find the cdrom. Is there a way to get this to adapt to the 50 pin mother bd connection.
