Intel Deskopt Board DH77EB Fail After Updating BIOS

[iusar]

Hi. I'm new user off community.

After executing the *.exe in Windows to update the BIOS, it turned off, tried to turn on and off again. Never give video

I have a CH341A programmer and i need to extract the BIN or ROM from the .Exe (or .BIO). The memory SPI is 25L6406E (64Mbit)

¿Could someone help me extract it?......or somewhere way de repair it.

My english is bad, i'm Argentinian. Patience please.

Have you followed "Instructions for Recovery BIOS Updates" inside "Leame (PDF)" from your link?

Yes.

Mother never shows nothing. Only blink a led and run fan, after it shut down and go back make to same.

¿Any idea?

¿Any idea?

My thought process:

EB0103.BIO size of 10,059,808 is not multiple of 1,048,576 (one megabyte)

UEFITool says EB0103.BIO has 32 byte header

Remove first 32 bytes from EB0103.BIO makes size 10,059,776 bytes = ten megabytes

Can use XVI32_Hex_Editor to do this, or use UEFITool Action->Capsule->Extract Body - both make same result

But you've said memory SPI size is eight megabytes

So I guess you would have to try removing another two megabytes

Which two megabytes? - I do not know, and UEFITool is no more help

is the 2MB the ME area ? , look for KRID with hex editor

Hi pfrcom and SMDFLea. Thanks for you replies.

During these days I studied the subject without success. The motherboard is still dead.

Can the damaged original bios be repaired?

I attached the damaged original bios. It's exactly 8MB. Read with CH341A. (V1.30)

I will continue studying the subject and I will comment as soon as possible.

size 10,059,776 bytes = ten megabytes

No it isn't - 10,059,776 bytes = 9.59375 megabytes - trapped by using Excel with decimal places set to zero

It's exactly 8MB

No it isn't - from bios-niki-25l6406e.rar I extracted 8,388,672 bios-niki-25l6406e.bin which is 64 bytes greater than 8 megabytes (= 8,388,608 bytes)

look for KRID with hex editor

KRID not found in original EB0103.BIO, either case-sensitive or case-insensitive
