Hello, I'm trying to install my WinXP on an Asus P4P800Dlx with ICH5R. I have two Hitachi 7k250 Sata drives. The raid0 array was created successfuly. First I tried a normal installation with F6 button at beginning. There I had the problem that first the iastor.sys did load, but after having created the partitions and formatted them, during second copy of iastor.sys I had always an error message saying me Windows was unable to load this file!!! I first tried with a floppy, then with an USB floppy, with severals disks, nothing does... So I decided to integrate drivers on my unattended installation. I tried severals method found here and there, but nothing did, driver could not load or I became errors in oemsetup.txt, getting blue screens during installation or after first reboot (just befor the grafical installation) Yesterday I finally could test the great raid package! Very easy to have the CD modified!!! The whole installation process worked well!!! I've never been so far with all the other methods I tried!!! Unfortunately, the second reboot, after installation has finished succesfully, my computer reboots after 10-15sec loading XP... I'm unable to access OS. My BIOS is uptodate (1016) and I really don't know where it comes from. Do you have an idea what I can test/do? I also would apologize for my poor english. Thx! Edit: I just wanted to note an issu I experienced during install: I've got a logitech Desktop MX keybord which worked well for all things I first tried, but during installation with unattended and Raid package, the keyboard did not work on USB. I had to use PS2 pins. Is this a known bug?
