I don't know what you want to do, maybe use AMI BIOS Recovery or something. Anyway, I have attached the BIOS Region only now and not the full HDR or the full SPI image (which Dell doesn't provide either way).

If you provide a dump it should be possible, obviously with a programmer. Do you know what part of the SPI image got corrupted like BIOS, ME etc?

@ plutomaniac
first of all thanks for replay and help, i have flashed the original bios file, after update complete the computer restart with no display. if have discovered the recovery key is FN+ESC but i cannot able to get the name for recovery file so i cannot recover with the keys, so read the bios ic to check if it was possibile to get bin file from hdr but i am not expert in this field so i stoped. if you can i will upload somware and send you a link. thanks again

Did you mod the BIOS before flashing or anything like that? That's a Skylake system so if the problem occurred after trying to flash the official Dell BIOS, it would be better if you contacted Dell first. That system is still covered by warranty based on it's platform. Do you know what exactly got corrupted? For example, if it's the BIOS region only we could replace it with the one from the .hdr but you will lose laptop-specific info such as DMI data, Serial Numbers etc which are found at the BIOS region. If it's the ME, since Dell includes only "Stock" firmware at their HDR, we will need to transfer settings from the dump you provided and then re-integrate into a "fixed" dump. If you don't know what region is the problem and are not interested for the warranty, we can start by replacing non-BIOS regions and see where that leads us. If nothing works, we will try the BIOS region as a last resort with the obvious result of losing some laptop-specific information.

donot worry about warrenty, dell rejected to pass beacuse i changed di mSata disk, i flashed normal bios not any moddded,.so you can start work, if you want serial number or other info i will send you in the email. bundle of thanks

Attached are two "fixed" files. First try "9350_dump_fix_me.bin" which only has a clean + configured ME Region changed. If that's the problem then it should boot. Otherwise, try "9350_dump_fix_me_bios.bin" which apart from a clean+configured ME also has the BIOS replaced based on the one provided by Dell inside the HDR image. If the second image works (ME+BIOS) then the problem was in the BIOS. I don't know how to get any laptop specific info out the dump in such case so you might have to live with it. But first let's see where's the problem and if these fixed SPI images can even solve it.

i test but i will tell you tomorrow because writting is too slow on 16 mb chip, bundle of thanks

EDIT: hi, "9350_dump_fix_me" is not working, no fan spin, no front led blinking, only led on power button. i will try second and post the result.
i tested aslo "9350_dump_fix_me_bios" but same result as first.
Can you get the name of recovery file to recove from usb?
Thanks

#86 RE: BIOS Modding: Introduction and Preparations by oldirdey 29.03.2016 18:00

@plutomaniac, can you tell me a tool to extract the bios region from Dell .hdr file?

edit: Managed to get the .rom file with the exe file and /writeromfile. But which software to take a look at the extracted .rom? For example to see the bios menu structure or to edit something.

edit2: With Andys Tools I got the ROMs extracted and with tool Xsearch I can search into them. Who can tell me how to find the rom with the bios menu inside to see if there are hidden menus. The goal is to change the cpu multiplier.

Thank you.

If you want to address a post to a certain Forum member, you should better write "@nickname". Otherwise the addressed person (here: plutomaniac) will not get an info via PM.

Thank you Dieter, didn´t know about it.

i used >AMI Aptio UEFI MMTool v4.50.0.23< with the SABERTOOTH X79 BIOS 4701
https://www.asus.com/Motherboards/SABERT...pDesk_Download/

but when i open the cpu patch tab then the tool crash...

so i used >Aptio UEFI MMTool v5.0.0.7< to check what is happening and there is no troubles ...should i use it to update rom and add the asm1061 uefi ?

I am pretty sure, that you can use it for this purpose, but I do not recommend to use it generally, if you want to modify an AMI AptioIV BIOS manually.
