160gb HDD – BIOS only detects 30gb

Got a new samsung 160gb hard drive, when creating a partition, the winXP setup only detects 30gb of the disk. Have tried everything and have tried manually setting the parameters of the drive, but it won’t let me change anything. This is a new motherboard (FOXCONN 760GXK8MC-RS SOCKET 754) and I cant understand why the bios can’t see the remaining 130gb, maybe there’s a simple bios setting Ive missed. If anyone thinks they might have a solution to this it would be great, any help at all would be much appreciated.
