Thank you both, opt_step and thanh2h opt_step (Modded Bios) - Security verification failed thanh2h (Modded Bios) - Accepted and flashed I'm helping a friend over the phone with this mod flashing. After thanh2h's modded bios flash his system wont boot up from harddrive any more. He can access Bios without any problem and sees the ssd and dvd rom, but can't boot from either of them. Since I don't have his computer in front of me, I can't tell whats causing this, but will look into this in a couple of days. He told me something about a failure message on the first boot up attempt after flashing. But many thanks anyway opt_step and thanh2h, will come back with how it goes. Regards Skugge
