@csorikam69 -

HI, many thanks for your support! Teh bios dump is ok, but the flash is not...

Hi @csorikam69

You need to set your PC in Service_Mode. You can do this by moving the jumper on your motherboard to the service mode pins.
You have a Dell Optiplex 3020 MT right?
So your motherboard is "mih81r, 12124–1 m"
Here is a picture of it:


I drew a red circle on the left side. That is the location of the pins to set your PC in service_mode. You need to move a jumper on those pins.
This is what a jumper looks like:


So turn your PC off, open the case, move the jumper on the pins where it says "Service_Mode". Close your case and restart your PC.
It should show a screen like this:


Press F1 and just wait until you can login again. Then restart again. Press F1 again and wait until you can login again.
Now repeat your flash command in FPTw: FPTw.exe -bios -f biosreg.bin
Now you should NOT get Error 280 anymore.

@Koven - Thanks, I forgot this one has jumper!

@csorikam69 - yes, once you do above, and confirm you can write with FPT, send me the biosreg.bin file and I will make NVME Mod BIOS for you.

Many thanks, I have flashed the bios, and its working!

@csorikam69 - you should not have flashed ANY BIOS from this page, at all with FPT!!!
You need to dump BIOS region with FPT, and send to me (or you mod yourself), then you flash it back. If you use any BIOS from here you will loose your serial #, Asset Tag, Service tag etc (you'll have someone else's info instead )

I thought he modded his BIOS by himself already.

Would it be possible to alter the dell boot logo to some other graphics?

HI,

A replace the motherboard to a Dell 9020 and I make a modded bios to this too.

The error is the same but I forget the solution, please help me...

I don't find service jumper on this motherboard

Hi, Thanks! I'm reading and reading, and understanding. The BIOS is ready.

Hello,

sorry for digging and bumping this old thread, but I think its the most relevant I could find for my question.

I am about to buy a refurbished optiplex xe2 (or an 90320) but I want to also buy an m2 disk and connect it on pci-express with an adapter and make it bootable.

So far, I downloaded the update bios file for xe2 and managed to get the HDR file and update it with the requested line in order to make bootable. However I am stuck on how to update it on the bios as it is not a ROM file.
On a second attempt, I also managed to extrack the ROM and BIOS files from the exe (with "phoenixtool250" OR with "universal extactor", not quite sure). However I haven't done anything apart from the extract.

I see that @Lost_N_BIOS has some answers to the questions that I need, would you happen to have a tut-like for DDCU or CCTK? Or maybe know a different way to update the bios for pci-express boot?
I know that I should have the optiplex in order to test the solution, but I want to know if there are ways in order to make the above request and then I would proceed with the purchase.

Thanks

@stfn - Yes, extract BODY of RAW GUID >> EB3001D5-F827-4938-95E2-5C8F644B966F
Make your own BMP of the same size and same format (BMP, same mode 8bit / indexed etc) Other formats may be OK, but I'd only test if you have a flash programmer

@thod_ris - Please link me to stock BIOS download page so I can grab the exe and the full model name etc.
Then I will check, but probably we can't figure anything out until you have system in hand, I prefer to use FPT so I'll show you how to go that route if possible (None of the files or methods you mentioned will be used)
I can't help until you have system, sorry. I don't know about flashing mod HDR, or extracted bios region from HDR, or how to properly mod HDR so it is flashable (it's broken once you modify it like a normal BIOS)
DDCU or CCTK only work on certain systems, so there you'd have to have system in hand to try too.

@DeathBringer may have already made NVME mod BIOS for that Dell model (XE2)? If he has, I'm sure it's probably already directly flashable, or he will tell you method to flash mod HDR etc
He knows much more about Dell and HDR than I do

@Lost_N_BIOS thanks a lot for the reply.

The download page for the BIOS is here, and is the one I actually used while following this guide (but as you said, I will need that).


I am still looking for a reasonable price for and XE2, so I will update as soon as I get it (most likely it will be from the UK, so it will also take some time to get to Greece).

@Lost_N_BIOS
need to know guide about stag & astag info of this type dell bios.
tried tag search in hxd but not worked.
is it possible to edit stag asset tag & uuid info in hxd without any other utility.
uploading my bios biosrgn part for testing purpose.
[[File:Region_BIOS_BIOS_region.rar]]

@thod_ris - That system's HDR file can be extracted into it's components using PFS extractor method, from there you will find BIOS region (but still this would not be used either)
We'll dump the actual on board BIOS region, edit it, then program it back.

@earthoo7 - Before I download that, what is this model?
Did you already try Dell tools to change these values (Dell Asset Service Tag DST) Asset and Asset_A209 are similar, but not same, try both
