P8Z77-V PRO - Security Validation Failed | Removing perm SLIC possible? Hi All, I've been trying to modify my bios with a permanent ASUS Slic 2.1, but I can't seem to write my BIOS back to the MB. I backed up my BIOS with the Universal Backup tool, which gave me a .rom file. I then opened this in Phoenix and selected Original BIOS, Manufacturer, SLIC, DMI and pressed 'Go'. I then tried to write this file using bupdater in DOS, but I kept getting a 'security validation failed' or 'security is missing', so I couldn't write it back. I tried to use USB flashback, but the LED just flashed a few times before staying lit, which I assume means that it wasn't possible to update. I did manage to use the Dynamic mode on a BIOS CAP file downloaded from the ASUS site and have activated successfully with that, but I'd really like to get a permanent activation working. Does anybody have any ideas? I'm not sure whether this is an issue relating to the fact that the bios backup is a .rom file, where my MB seems to take .cab files. Much appreciated!
