@otraver .BIO files are a special format and contain extra stuff, it is not simply the contents of the chips. For example, on a DX58SO, the .BIO file is ~3.6MB, even though the flash chip is only 2MB. It also doesn't have the board's unique information.

Since you already have a flasher, you should start by reading the contents of both of the chips. You must preserve the unique data on the chip, such as board ID, serial number, MAC address, etc. Once you have the backup dumps of both chips, maybe someone can help you fix them.

@turnip

Sent your bios back.
Should work once flashed but run the maintenance manager to clear the setting. The bios you dumped was previously customized with the ITK (flex) utility.
If it does not boot or exhibit the same issue as your dump or cause random watchdog BSOD on sequential boot I can eventually see to rebuild the NVRAM partition from mine last backup.
To know if it random BSOD just reboot the UEFI-OS on the login screen without log-in for few time and without manually cutting\removing the power cord in between.
Usually if it doesn't BOSD on the third attempt you are good to go.

I've removed the flex entry, adjusted some NVRAM entries (some will be builded back on later boot stages once cleared) changed the main firmware volume size added NVME support, OROM IRST 15 changed the TRFC value and updated the microcode to the latest available, maybe more dunno.
There still some invalid NVRAM entries left.

The bios you dumped had all data required to restore your own board unique data, so.. eventually you can do what ever and still restore it with the hardware programmer.

Also, since I saw an REFIND value within the boot path: know you need to disable RAID to get DUET working without providing an full EFI (SATA) RAID (DXE) driver embedded directly within the firmware.
ICH10 RAID disk once masked require their own special EFI driver over the filesystem type to get em boot in UEFI.

Also, made and sent you one with a NVRAM without settings.
Report back.

To modify the motherboard of a computer it is essential to know the system configuration as this is the only key to choose an appropriate motherboard for the computer.

Yesterday I received the CH341A programmer and obtained two .bin files. But I don't know how continue.,
I think that the mobo is stay alive because If I don't install any ram module I can hear 3 shorts beeps. But No video.
In my youtube channel I uploaded some videos with all the test I tried without any good result.

Nice, but I wouldn't waste an single €1.00 on downloading something stored on earth, also your board is "not" actually your board anymore.
Change at least the MAC address and HARDWARE ID.

@otraver

If you re-install the OS those will change with the BIOS assigned MAC address, so save them on a sticker.

I apologise in advance if this is in the wrong section. I did use the search function and couldn't find a thread for this.

Intel has stopped support for this board in Nov 19.
All the links i have found direct to the Intel page that is no longer available.

I am currently using a CH341A to update the bios as the board started Code 32'ing. ( this is a common issue )
I have version 70 of the bios but when i transfer it in to CH341a programmer its says "File length, beyond range of will be ignored."
I have loaded the bios any way and it flat out just does not work.

Does anyone have a bios file that will work with the CH341a for this board ?

Thanks in advance.

Hello, did u visually identified the correct bios chip ID as also identified by CH341A?
By the way the last official bios version for ur DZ77BH-55K
BIOS Version 0100 - BHZ7710H.86A.0100.2013.0517.0942 (*.BIO for Intel recovery mode by jumper and USB)

U should also take a look here:
[GUIDE] The Beginners Guide to Using a CH341A SPI Programmer/Flasher (With Pictures!)
[Guide] Using CH341A-based programmer to flash SPI EEPROM

Hi MeatWar,

yea i have found the right chip model its the MXIC MX25L6406E

Yea i know the last official bios was 0100 however i have not been able to find a working link to any other bios that the 0070 i have found.
PS. the link you provided is forbidden

ill take a look at the guides thank you.

however i am still stuck with out a bios that i can use in the CH341A - kinda hoped some one had a back up saved that they could share a copy of with me, i dont even mind what version.

Try linked file now
If u need the others versions of this Bios, i`ve got a almost everything from Intel Series 4/5/6/7.
Im not very experienced in all kind of bios with CH341A...ask help in that sub-foruns i linked earlier to u and Intel bios r hard sometimes to fix... Good luck.

So i have read through the the guides and its pretty much a no regarding moding the intel bios. I could pay some one to MOD a bios but i don't want a modded bios i just want a copy of an official bios that is compatible with programmer.

I have gone ahead and order a new bios chip with a bios already installed. My plan it to try and rip it from there and copy over to the chip without the need for soldering. Worst case is i do need to solder the new chip on and that's a whole other story as i haven't done it be for, but seems like i got nothing to lose either.

If i do manage to get a copy off the new chip to work i will post a link so it can be used by others to maybe get dead boards working. i wont know what bios version until it turns up however. i am expecting 0057 which i believe is the bios the board shipped with.

Finger crossed lol.
