I also tried to add only the driver would I use in my case the "Intel ® Desktop / Workstation / Server Express Chipset SATA RAID Controller" but got no success, the same previous error ocurred, But in another different line. ? Yes, i'm sure. I changed the BIOS setting AHCI to RAID . I figured I could add a HDD later, for this reason I decided to install the RAID driver. The W2k3 is not original, I have no license. would be possible to add these drivers to the UNATTED.TXT? If yes, how to proceed?
