ahcix86.inf, ahcix86.cat, ahcix86.sys, txtsetup.oem, ahcix86. These are the names of the files (drivers) that you need in order to install AMD AHCI on Windows XP. (look at post #234 and check the contents of the package). Unfortunately, I don't see ahcix86.inf in your Last Session.ini; I see amdhub30.inf and amdxhc.inf which are (if I'm not mistaken) USB 3.0 drivers, so that's probably the reason for failing. So, download the package a few posts up, unpack it and integrate it into nLite (in textmode). That should do the trick. And yes, change the BIOS settings to AHCI. Cheers
