Hello Everyone. My Little bros birthday is about to come this week, i bought him a new PC as a congratulation gift also. but i wanted to build his new Pc as Windows XP because of the games compatibility issues. i thought i'm gonna finish this now. but the problem is My Windows XP Disk only support IDE thing, i want to have his pc run on AHCI for faster PC, now i use NLite (this is my first time to use) NLite v1.4.9.3 but the problem is, after i burned My integrated Windows XP SP3 32bit then boot on start up, after few seconds of waiting The Windows is loading files etc. it says "the file ahcix86 could not be found" press any key to terminate the setup. maybe because i downloaded AMD AHCI/RAID files on everywhere. (which i no trust) =( but then i googled this one and i found out everything here . http://www.msfn.org/board/topic/171216-the-file-mvs91xxsys-could-not-be-found/ i went to this post and i red on @Fernando reply on #19 . here : Here is my statement: It was a mistake to integrate the AMD AHCI driver named amd_sata.sys. This driver is only usable with Vista, Win7 and Win8, but not with Windows XP. The correct 32bit AMD AHCI driver for Windows XP is named ahcix86.sys.The message "The file ahcix64.sys is corrupted" indicates, that you have tried to integrate a 64bit driver into a 32bit OS. That was a mistake as well.If you are searching for a suitable AMD AHCI driver, you may look into the start post of >this< thread. Note: You will find the AHCI driver listed as RAID driver, because the AHCI supporting AMD Controller is named "AMD AHCI Compatible RAID Controller".Windows XP Setup is very sensitive regarding wrong textmode drivers or wrong AHCI/RAID Controllers, which have been checked when doing the loading or integration of the textmode driver. So it is a good idea to integrate only 1 single AHCI or RAID driver (the suitable one for the SATA Controller, where the system drive is connected) and - if you get a list of different SATA AHCI/RAID Controllers during the textmode driver integration - to check just the correct one and not all of them. now, i tried to follow his #3 i downloaded the file here http://www.win-raid.com/t29f25-Recommended-AHCI-and-RAID-Drivers.html and i went automatically on MEGA : https://mega.co.nz/#!kENkwBSC!Ef3jjR8MDmMCL536yX8AwHsQ1w4g46JaYMskpdG3Fok i unzipped the file and everything and then i run NLite and folow @Fernando's #1 "The correct 32bit AMD AHCI driver for Windows XP is named ahcix86.sys." but i only see .INT file which is the ahcix86.inf i can't see ahcix86.sys when i try to integrate it to NLite, i hope that his #1 Statement would fix my prob. My Question is How to integrate the ahcix86.sys on nLite just to follow His advice. i only have 1 remaining blank disk. hehe . i wasted 1 disk awhile ago. =( thank you in advance . PS: super noob here. =(
