Does the drive not show up in drive selection window when you boot XP installer? Or are you getting that far?
If the correct drivers for your SATA controller and bit-rate are loading but malfunctioning, then try slipstreaming into the XP installer: SATA Drivers - Slipstream into Windows XP CD
I would also remove the XP partition to let the installer create it as there is a slightly different partition table.
