AHCI drivers not in list during XP install

Thank you in advance for any help.

I'm trying to install AHCI and windows XP on a new system. Motherboard: GA-EP45-UD3R

I have:
1. Set AHCI in bios
2. created a floppy which is supposed to contain both the SATA RAID and SATA AHCI drivers (ive done this 3 different times. downloaded the files from gigabyte, downloaded them from intel-the "32bit floppy disk utility" or whatever, and ran an exe on the motherboard cd-rom that copies the drivers to the floppy. The files on the floppy are iaahci.cat, iaAHCI.inf, iastor,cat, iastor.inf, Iastor.sys, TXTSETUP.OEM. )
3. Everytime time, after I start installing XP and press F6 to get to a list of drivers, my list only has 4 choices, all of which are "SATA RAID" drivers, but the list is also supposed to have AHCI drivers on that list, and it doesn't have any.
