Replacing BIOS Logo in source files for Flashing

[Blacktape 3]

I am looking for information on the procedures to replace the integrated BIOS Logo on several laptops. The model numbers are the P650HP6-G, and P650HS6-G.

 

In the past, we have been able to replace the logo on those BIOS's using an Asus BIOS Logo tool, and Secure ROM Signing tool successfully.  However, with newer BIOS updates, I have been getting an error message "18-Error: Secure Flash ROM Verify Fail." So I have been staying with older BIOS versions instead of trying to force a bad flash.  The P650HS is still using a .BIN for the main BIOS flash file, however, the P650HP6-G has changed from a .ROM to a .8M or .04 file, depending on which method of flash used.  One file size is very different from the other (most likely because of a combined ME and BIOS flash code in one file.  The trouble is, I am unsure whether these are to be seen as a normal BIN or ROM file, just named differently, or as a completely different type of file.  I am using the BIOS flash file that is used only for the BIOS, which should be free from abnormal code arrangement for multiple components.

 

I am in need of an appropriate Logo replacement utility, as well as the digital signature utility for Secure boot.  If there is the matter of having a valid key assigned to the company for this purpose, I can present that to my managers for their follow up.
