Hello, the guide on the first page was very clear and concise about which drivers I should be using and how to implement them to install my Windows XP 32b OS onto my modern computer, But alas I still have no success. I have the Asus Rampage IV Extreme x79 chipset motherboard, and a RAID 0 main drive configuration with two OCZ Vertex 2 SSDs. I currently have Win7 64b running, and wish to dual boot to the old OS for compatibility. My failure comes from the text installation portion of XP (aka the first step). I have tried slipstreaming the appropriate drivers several times with no success. Immediately after finding this article I tried slipstreaming the slightly modded/recommended drivers for x79 in the first post, only to have the exact same error. During the initial setup of windows, regardless of IDE/AHCI/RAID mode configuration, the setup will fail to load a sys file and shut down. In this case "iaStorA.sys" is always missing - the supposedly slipstreamed driver for SATA RAID. My BIOS settings have no effect on the process in the least, always the failed sys file error. I have even reduced the RAM levels in my machine to a single chip (2gb) as recommended in part 3 of the guide, no success. The two SSDs being used to run the OS are in the 2 internal SATA 6GB ports of the Intel controller, and the disk drive is connected via one of the 4 internal SATA 3GB ports under the same controller. To erase the possibility of a faulty CD/DVD drive, and the need to try the CD/DVD drive under the Asmedia controller, I have attempted to take the re-imaged XP setup disk (slipstreamed) and install it to boot from a flash drive, using the utility "WinSetupFromUSB". The result, a much faster initial setup load that fast forwards to... the same error "iaStorA.sys cannot be found." I can't bother with hardware compatibility issues yet till this is resolved, clearly my drivers and disks never match up properly to even get me to the select screen for the XP install. What could be the problem? What should I do?
