Hi,
your motherboard most probably needs an "ide" hard disk. The latest motherboards use s-ata (sata) or sata2 slot.
I would suggest you check motherboard's brand name and model then you go to manufacture's web site and find infos about it.
Alternatively you can download a free utility "CPUID" aka CPU-Z and it will tell your motherboard model (plus many more infos)
