What I want to do is to install the drivers for the RAID class Controller from a functional WIN XP, if I integrate I will have to do a full repair of my copy of WIN XP, form the CD. I wish simply to install the correct driver, my Win XP SP2 is running on the Sil controller, in Device Mannager I have: SCSI and RAID Controllers Unknown Device (this is the nForce RAID Class Controller) Sillicon Image Sil 3114 SoftRaid Controller (wich is functional and my 2 HD are connected to it) My guess is that if I fix the problem and install "nForce RAID Class Controller" I will be able to unplug both disk from the Sil controller and plug them into the nVidia SATA controller, and my RAID will work ok, and perhaps, faster. This seems "loco" but I already do it form a VIA based mainboard to nForce, aparently the info in the drives is similar in several RAID systems, I had to reconfigure the RAID controller by pressing F4 and setup the RAID in the new mainboard, by specify "Don not delete data", then it simply boot like charm. The hard way will be: unplug both dirves form the Sil and connect them to the nVidia SATA Controller (in the same order), then boot from a Win XP integrated CD and perform a repair of the previous system. This is complicated, and the main problem is that I cannot make a Gosth copy of my RAID 0 to the IDE drive anymore, Gosth post some error too, so I'm trapper in the Sil controller for now and I cannot do complex test becouse I risk to loose Win XP, and believe me, I had programs installed that I cannot loose. Alejandro P.S: I tryed the floppy with the WinXP/Legacy folder from the 6.70 but keep reciving the error.
