The Asus p8z77 version 1805 series bios seems can not be modded anymore. They always failed the security check during updated.
Please try 2.14 version in first page of this thread. I think i've found and fixed the FFh padding 'bug' (although it is deliberate code - but I can't for the life of me remember why I put it in) Andy
Andy thanks a lot for the new version and your support i really appreciate it...... As for the slic mod it's still unsuccessful, i don't know if it is any help but i have as attachments tha acpi table extracted from rw everything of the original bios and the one i modded with v2.14 of phoenix tool with Dynamic method, SSV2 gives me error.... Original: View attachment 20786 Slic mod: View attachment 20787 My regards, ribben
I see...... the 2.1 SLIC is there but the oem/table id fields are being replaced Will Ix In the mean time the most obvious solution would be to mod with the ACER 2.1 SLIC so the change of the oem/table ID doesnt matter Andy
The Asus p8z77-v pro bios 1805 has been changed its structure. it's different from 1708. I modded 1805 with phoenixtool 2.14 and earlier verions but the outcome were failed in security check and could not be flashed. I flashed witn Asus built in EZ updater 2. Any idea?
Just to be clear... you tried a new module mod with 2.13+ and it DIDNT work..... because it should have done I will look Thanks Andy
Thanks. The only difference between Serg008's mod and a tool mod I can see is the two module are inserted the other way round. Other than that they are identical. Does that really make a difference?? Andy
Newer HP BIOS's are RSA signed & so they aren't easily decrypted/modifiable. Its better to choose another vendor if you re interested in modding the bios.
