@Lost_N_BIOS - is it still a chance to save this computer? 😉

Hey @Thangle - I just replied to your PM, sorry I didn't know you already were posting here. I don't know what you meant about changing regions, etc, unsure what BIOS you were using and how, so I can't explain why it didn't work for you.
What I will do is combine your two files in hex, do clean/Update ME via the guide here, replace BIOS region from stock HDR, and then split and send back to you (Cleaning/Update ME will also split the files automatically for you if that's a problem to do manually for you - FYI)
Is that what you did already? I see the main issue, in the main BIOS volume, the "Dell FV Nested" volume is corrupted, so if you did not replace the main BIOS volume, or the entire BIOS region then that would be why it's failing.

Stock Main BIOS volume used (may need to reapply/reset Asset Tag, other board specific info)
FD Unlocked
ME 8.1.40.1416 >> Cleaned/Updated to 8.1.72.3002


BIOS1 - Test first, this contains your original dumped NVRAM, system specific info may be there, but could also be corrupted so may fail
BIOS2 - this has only stock/bare/empty NVRAM, so nothing specific to your old system will be here, it will need added via hex or with Dell DST Tool CD/DOS Files

Here is Dell DST (A209 is not same as ASSET.COM/EXE - both do same/similar, but are different versions, so if you use and one doesn't work for you try the other)

Hi @Lost_N_BIOS

Thanks a lot for your effort to help me out. I tried to write BIOS chip with 8 pin but got this error message "Chip with the contents are in disagreement". The 16 pin BIOS was successfully written.

Do you know about this error?

Thanks a lot @Lost_N_BIOS. The T5610 booted =) I used "Auto" in CH341A programmer which erase->blank check->flash

@Thangle - yes, always erase, then blank check first, then open BIOS and write/verify.

Hi @Lost_N_BIOS!

Which guide are you refering to and which tools/software did you use. I am trying to learn how all this BIOS hangs together.

@Thangle - if you mean when I mentioned ME Guide in post #32, this is what I meant (All tools and method for that is there or linked in there) - [Guide] Clean Dumped Intel Engine (CS)ME/(CS)TXE Regions with Data Initialization
If you meant some other guide, you'll have to tell me what we discussed or where else I mentioned guide.

@Lost_N_BIOS - Thanks, unckear from me but it was post #32 I was referering to. Thanks again!

Good day, will you PLEASE split the BIOS of my Dell Precision T7610 for me into 4MB and 8MB? I am having a tough time doing that. If you inbox me your email I will send it to you. Thanks in advance. I only have the .exe from Dell website.

I have exactly the same problem with my T5610, no boot just 1-2-3 LEDs on. I've just read the whole thread and I would like to give it a chance . Though I'm a total newbie in this BIOS stuff, I'll try to reproduce the whole process.

@Lost_N_BIOS helped to split the original BIOS file, and he uploaded the two resulting files.

BUT the downloads had expired so no way to get them. I would really appreciate if anybody who has these files contacted me and give a helping hand with these missing files and some advice.

@Thangle

Any chance?

Thank you very much!

I have totally forgot this website and my thread, I got one private message from Dell EMC Community because I also post same thread there, then I got the link for this thread, and google chrome help me to recall the username and password, or else after more than 2 years, I can not remember this password.

Please also thanks my NAS, I can find these old backup of T5610 bios, I already re-install that laptop many times after I fixed my T5610, but I have a good habit, everything important I like to put into my NAS, and also use my another backup NAS to have a copy of that, in case NAS damaged.

If you already have programmer, you do not need my bios files, you can read them from your board. But I still put them here for your reference.

Please note this old bios file can not boot your computer, you need change it according to my post. you can use my edited bin file directly, but I am not sure if it will conflict with your mother board, because some configuration was just for my board.

@go2net

Thanks again for the files, and for all your effort taking time for recovering password, looking for the files on your NAS etc. Really appreciated!

I'll take a look for the whole process soon. As I'm not an expert in this stuff I need some learning before.

Cheers

Today I have new experience whit my Precision T5610 workstation.
I recheck all parts (2xCPUs, 4x4GB RAM, SSD HDD, Nvidia K4000 3GB video-card e.t.c.) in similar Motherboard. As expected all are working OK.
I make a dump of its SPI flashes with FPT.exe in dos mode and obtain Complete BIOS dump, from FPT 12MB with this command:
DOS>FPT.exe -D DUMP.bin
Forget to notice that my friend's dump is version A08, and mine is latest A19.
At my machine i put both chips on a sockets so now i can experiment with them easily.
I am using Linux Debian 10.
Then modify the script with my real directory and split it into 8MB and 4MB.
Then programme both SPI flases .
As i expected with its data no boot, but initial check now blink different way.

I try write private messages @go2net and @Lost_N_BIOS, and try to upload both dumps here in *.7z format, but it does not allow me to upload files.
may be don't have enough post to do that.

Now i will try to rebuild first BIOS part with of 8MB.bin file with the one extracted from the original T5610A19.exe as explained in the first post in the thread and at post#42.



Thanks in advance to all good guys!

Just to report my efforts finished with successful boot ☺️
Great thanks @go2net!
Without his 4(8)MB_NEW.BIN I would still be unhappy
