Great, now we also have the “v6”. At least if the changes justify a new version No.^^ Wich leads me to the question about remarkable changes of Hard and/or Firmware?
Please be carefull with “naming” of system relevant informations! The only “5.12” number i could find was the Core Version 5.12 on the Bios Main page.
And that number is the same for v3 and v4. (Missed to check it on my old v5, but i could bet it is the same.)
Could it be the Bios Tag that “makes” the different Bios versions compatible? At least for v4 and v5 it is the same.January 19, 2018 at 8:24 pm #77280
The System BIOS Version is 5.12 on my V6 too, so it seems not to say anything. But the BIOS Tag could be really interesting.January 19, 2018 at 8:44 pm #77312
@Moe how did you extract the .rom BIOS?
BTW with AMIBCP you can see every information in every BIOS and even potentially unlock extra features.January 19, 2018 at 8:59 pm #77318
With AMIAfu https://ami.com/en/products/bios-uefi-tools-and-utilities/bios-uefi-utilities/. I already tried to unlock features, but it not as simple as settings access rights to user.January 19, 2018 at 9:08 pm #77319
Access rights? I’m able to open the ROM without problem.
The only problem is that I don’t have a EZBook yet :’)

@thegiolly But can you save it after enabling the advanced features menu?
I can also confirm that my V4 (first model) has a good keyboard and wifi. But I have that rubbish NCard eMMC (doesn’t worry me I use an SSD anyway) Since my bios is unlocked I’m leaving it and never bother to upgrade.

The problem is that with AMIBCP you can only edit the .rom file and they all seem unlocked, even the v5 and v6.
I found out looking at the log that in the v5 and v6 it looks for a specific combination of hex parameters and if it’s matched it hides the two extra menus.
Now I have to find out where those hex data is stored.January 20, 2018 at 9:42 am #77345January 20, 2018 at 11:05 am #77347

Can you tell me where are these hex parameters stored? In NVRAM? That case we can unlock all versions easy.January 20, 2018 at 11:34 am #77352
@giovani I already edited the hex file changing the suppress region to false, but I seems to be not enough (see my posts)
The 0A is the suppress if enum
The 82 is begin of a region and says the Suppress if has two bytes
The 46 is the condition variable which is in your case true, which means suppress, 47 would be false so no suppress, but it don’t work for meJanuary 20, 2018 at 1:06 pm #77356

Remove both if helps? Like ont scren shot left side (v4 Bios).January 20, 2018 at 1:31 pm #77358January 20, 2018 at 2:40 pm #77360
I Saw that you changed the order around the suppress if command, but what did you change at the beginning of the setup.bin, checksum bytes?January 20, 2018 at 2:55 pm #77361

At the beginning? Nothing, just changed the order as you saidJanuary 20, 2018 at 2:57 pm #77362
But I checked the byte code and there are changes from the original to updated at the beginning
