After initial failures because I was adding the wrong drivers, I finally got this to work for XP Pro x64 with my new Dell Inspiron 530s. It was preloaded with dreaded Vista 64.Drivers I need to incorporate into the burned ISO image using nLite:1) Intel(R) Chipset Device Software. This was needed for the HD controller. Make sure to get the one that supports x64 bit XP.2) Intel Matrix Storage Manager Driver for x64.Oh, another thing was when selecting the matrix storage manager driver I clicked on the Plug n Play (PNP) mode, and NOT the text mode.It was not an easy process, but 7 burned CD attempts later it did get me past my problem of the install not finding my hard drive because of not recognizing the SATA hd. Patience is the key and getting the right drivers slip-streamed. Thanks to everyone who responded!
Hi. When I try this with XP Pro 32-bit, it gives me "Setup is inspecting your computer's hardware configuration...". When I try this with XP Pro 64-bit, it let's me get into the partitioning section, but when I tried to format the main larger partition is gives me an error. Should I just erase the partion and try and create a new one, or will this fry me even further? My hard drive is an Hitachi 500 GB  HDP725050GLA360. Any help is much appreciated!
