If anyone of you kind people can help me, i would be most grateful. Heres the story. My nephew has a Toshiba A200, with Vista HP installed, but he developed an extremly bad virus which pretty much took over the machine, and as my sister uses it also, she told me that neither of them liked Vista, as it continued to cause problems. Anyway, i asked tthem if they wanted me to downgrade it to XP Pro. So unknown to me the consequences of this, i removed Vista from the Partition, and began installing XP, only to run into Blue screen saying it can not find the hard disk. Having gone through many forums, seeking an answer to this, i finally found a method to bypass the Sata drivers, so the machine would install Xp. But now i have run into a wall, that i cannot get over, unless some one here can help. I need iastor.inf. This is the only file i need to complete the installation, i have downloaded the IATA_ENU file from Intel, but as i suspected, i cannot extract the file as my hardware does not support. So what im asking, is if anyone here can extract a copy of this on their system for me and either send it to me or post it so i can download it, or knows anywhere that i can download a standalone file, then that would pretty much make my week, as this has been an awfully long and painful process, trying to solve this problem. Typical Vista hey!!! Please please please if anyone can help, i will be very very grateful. Thankyou for your time.
