AFAIK HII is built at some point - when I was messing around with DMI (WriteOnceStatus), at some point I also didn't have HII data, but I don't remember how I rebuilt it - probably after flash using fpt ??? On ASUS you need set PublishResources but on other motherboard I don.t know: https://github.com/ab3lkaizen/SCEHUB?tab=readme-ov-file#asus

@Dietmar After edit data in WinHex no need calculate any checksum ?

Why you not use UEFITool ? offset is same as in real bios in ru.efi +16 bytes right?

@Dietmar Then make a copy of the BIOS with a programmer, e.g. CH341A, by connecting it to the SPI port on the motherboard - I have already written about this: https://msfn.org/board/topic/183464-compiling-acpi-v20-driver-for-windows-xp-sp3-and-windows-2003-sp2-x32x64/page/180/#findComment-1286092 Do this several times and use the verify command.

Make current bios full backup: fpt -d backup.bin Then flash another one. If something be wrong then you always back flash backup.bin

In bios dumped from mobo NVRAM data present also after 0x182FFFF: I found last string "NVAR" in offset 0x1FB8D9E:

@Dietmar Do your motherboards with i219 cards have the ME region and did you have to disable it for the i219.sys driver to work?

@Dietmar BIOS dumped from mobo also have some NVRAM settings but BIOS from seller not:

@Dietmar Yes, in bios from seller no MAC addres. In Gbe region dumped from motherboard is properly i219 MAC:

I don't remember - I think I already buy had it flashed, but I also wanted to have a version without any data, e.g. without DMI, NVRAM that's why I also wrote an e-mail to the distributor to send me the bios. Simply try flash using fpt.efi - maybe this tool not erase current MAC ? fpt -f bios.bin fpt -bios -f bios.bin - program only bios region but I don't know if this is OK if update bios - maybe this is only used for mod exactly same version bios e.g. if you change logo or something https://oldrigrevive.com/software/intel-fpt/

@Dietmar But you don't have to update somehow - maybe through FPT just only bios region - I'm not sure. Along with the bios, I received the following information via email: "Please remember one important thing - when programming this BIOS using a programmer, the MAC address for LAN1 will be deleted. The MAC address for this network is saved in the BIOS. It is programmed with the eepudate program." LAN1 is i219 card Be careful. Before you write this BIOS, make a backup of the current one, preferably using the CH341A programmer and also via FPT !!!

Which bios I send to you because I already forgot ?

Yea - I also noticed my post and Dietmar post several times - probably forum glitch. Please delete doubled.

I couldn't download it anywhere either, but I obtained it via e-mail from intermediaries - from the motherboard seller and from the Advantech distributor in Poland - elmark.com.pl

This is not same as change ME State to Disable. me_cleaner delete some ME partition from BIOS - I test this on other motherboard some time ago: root@debian:~# dir me_cleaner-1.1 me_cleaner-1.1.zip root@debian:~# cd me_cleaner-1.1 root@debian:~/me_cleaner-1.1# dir 1408.rom COPYING me_cleaner.py README.md root@debian:~/me_cleaner-1.1# python me_cleaner.py -r -t -d -S -O clean_1408.rom 1408.rom --extract-me extracted_me.rom Full image detected The ME/TXE region goes from 0x1000 to 0x180000 Found FPT header at 0x1010 Found 15 partition(s) Found FTPR header: FTPR partition spans from 0x94000 to 0x109000 ME/TXE firmware version 8.1.2.1318 Reading partitions list... ????

@Dietmar This is how to make a 32 MB BIOS copy: And your BIOS is probably old - 08/14/2019 (https://ibb.co/vxZzQfDQ) I have 07/20/2022 -

You probably not read previously edited post on forum: https://msfn.org/board/topic/183464-compiling-acpi-v20-driver-for-windows-xp-sp3-and-windows-2003-sp2-x32x64/page/180/#findComment-1286092

No, this not help. I must have accidentally changed something in the BIOS when I was checking the RU.efi and other tools. Now I have reset the CMOS and set everything again, hidden options, disabling ME state and.... Works back - Ufffffff....

@Dietmar F..k i219 card stop working on both WinXP 32-bit and 64-bit - network cable unplugged - I don't know what happened?

Your mobo has 16 MB flash size ? Mine has 32 MB. To backup full bios use Intel FPT e.g efi version in UEFI Shell from CSME System Tools v12 r38.rar: https://mega.nz/folder/qdVAyDSB#FLCPaDVIsPYiy2TAUjD7RQ fpt -d dump.bin fpt -verify dump.bin I dump also using SPI port and CH341A programmer:

@Dietmar Yea, in your bios Setup Item Hidden offset is 0x132F Now you possible Disable ME State ?

Dump your BIOS and send me to check offset for BIOS Lock - my is B52: Offsets can be found offline in the bios file using ifrextractor.exe - for me offsets same from sceefi.efi and from ifrextractor e.g. Setup Item Hidden:

@Dietmar Maybe HII unlock after some edit DMI data - after buy motherboard I set some DMI data: https://forums.mydigitallife.net/threads/dmi-write-error-err_dmi_read_only.88282/#post-1834723

@Dietmar For me HII database present and sceefi generate settings.txt OK
