Computer doesn't see new components

[Inferi0r]

Hi,

I've a new computer with Asus P5QL-E motherboard. My Samsung Spinpoint F1 HD103UJ and Samsung SH-S223Q are connected trough SATA and where working nice. But I've also a (working) Philips SPD2411BD brander and Samsung SpinPoint P120 SP2514N HDD which I want to connect (throught (p)ata)). I've connected the components one by one to the motherboard and power supply (Cooler Master Real Power M520) but my computer (and BIOS) don't detect the hardware at all. Have I change some settings for using pata and ata components in a computer or what can the problem be?

Thanks for the further help
