The board should be arriving later today, along with most other components for a new build, and I am preparing now. I highly doubt that the motherboard is shipping with the latest BIOS update, and I want it modded anyhow. This board is EFI. I would like to update the BIOS prior to installing the OS. I intend on using EZ Flash. Regarding the mod, I would like to do a permanent mod using the DMI method, but that seems to be impossible without first having the OS installed. That being the case, I was going to use the Phoenix Tool 1.97 to do a Dynamic method mod of the BIOS I have downloaded from ASUS. However, I have read conflicting information regarding the need for an RW-Everything report. Also, I have received the following error when attempting to verify a certificate: "Complete SLIC (2.0) (A M I OEMSLIC ) does NOT match certificate (x1)" At this point I'm wondering if I can ignore that message or not. I've performed a few mods successfully in the past, but I'm not sure how to proceed on this one. I appreciate the help.
