The Extensible Firmware Interface (EFI) is a specification that defines a software interface between an operating system and platform firmware. EFI is a much larger, more complex,OS-like:4 replacement for the older BIOS firmware interface present in all IBM PC-compatible personal computers. The EFI specification was originally developed by Intel, and is now managed by the Unified EFI Forum. by Wikipedia
Can the EFI BIOS be modified to include a SLIC 2.1 certification? My original bios has been modified to include SLIC 2.1.
I guess it is a AMI aptio firmware...could you please post a link to the EFI? I'll have a look at it later......I guess we need MMtool Aptio therefore.....also I can try to open it another way. In fact we are NOT able to mod (U)EFI...if we are lucky, we can exchange a existing SLIC yes...but we need the tools. I'm worried about (U)EFI, because there is no (usable) tool leaked so far.
I have made it sticky and have edited the thread title, since these are surprising news....I thought it would take more time..but now a popular board has moved to (U)EFI......hmmm...
I Think After Few Months or Years All M\B's May Move tho these Technologies,then Modding will bcome imposible... So any Programmers,or others can take it as a challenge,also the One who finds it must be well appreciated......
Everything depends on the availability of the tools. More than two years ago we (I) knew nothing about SLIC and bios. Now we can mod them, so why not the EFI? New challenges will come......no tools, no mod, the only real chance to prevent modding is to hide the tools.....
I did some tests: Indeed the bios can be opened using EzH2O.exe, which is originally made to open Insyde EFI bioses when renamed to *.FD. The good thing is that the (U)EFI bioses are or could be similar in structure (U=unified). This would mean that there will be only one new structure in the future! Anyway I couldn't find a SLIC...by searching for the RSA1 string (public key data) I could find what looks like pubkey data, but it doesn't match a known pubkey of ASUS.....Also I didn't find RSDT and no marker.....more work to do! Feel free to play with EzH2O.exe. Access the physical memory and have a look....

From what i read the UEFI supports loading of payloads. Maybe the slic table and other mods can be loaded as payloads. What do you think?
OMG I hope this is not the end of modding? I don't really want to go the PCI/PCIe Nic solution that has been explored with other Efi Bios that can't be moded. Does this only affect boards with Intel processors or will AMD boards also have the EFI Bios in the future?? this is a very good thread to follow for people who want to built a new system. BD
I don't think this is the end of bios modding as the insyde efi bioses are already moddable. But we do need the correct tools which are not available in the wild yet. I have this board and i think i will hold of updating till we can see some real conclusions.
EFI BIOS is the future because of new ACPI specs and the ability to have more instant on type scenarios. Also as Hard Drives get larger and larger GUID partition tables will be the only type that will be able to handle these larger sizes. The catch-22 to that is the only type of BIOS that can boot from GUIDPT are EFI BIOSes.
Definitely EFI BIOS will be flashed into my P5Q Deluxe. However, stay with 2201 for now since there're still a lot to play with.
