Thanks, 1. Because the Windows XP SP2 disc will not recognise the SATA hard drive. (Hard drive works fine). 2. I am not sure, it is a laptop which gives no options in the BIOS to change SATA mode. 3. One from the nvidia website as I have no idea which one of yours to download. 4. The disc is a Windows XP SP2 disc, the problem is that it does not give me an option to do text mode in nlite. BTW this is a compaq F500 laptop. Thanks.
