I am looking for win xp sata drivers for...

Download Matrix storage manager, all the instructions on how to downgrade to XP are there.
These are the drivers you need:
iaAhci.inf, iaAhci.cat,
iaStor.inf, iaStor.cat,
iaStor.sys, TxtSetup.oem.
readme.tx and license.txt

read the readme.txt its important!!!!!!!!!

CATS 3073 is not the model number.

The model number is gonig to be something like: L300-EZ1004X. It will be on the back on one of the stickers. If it is not there or not readable, you may be able to get it from the BIOS. To access the BIOS, right after you power on the laptop, it will tell you to press a certain key to access the BIOS/CMOS/SETUP. Usually there is a general information page in there with that info. Don't make any changes in there.
