It's exactly what I have done (except extracting since I have already the .efi file)

---

yes

efi/boot/bootx64.efi as stated

That is the way I try to boot but it shows black screen.

Wait
Maybe with freedos I have to do the same???? probably that is the mistake I made with freedos?

@Cryo
Use empty formatted USB-stick without FreeDOS.

@DeathBringer

I already told you I tried so many times that way. It doesn't boot, sometimes it just turns off.

@DeathBringer

Thanks for the kind help and time given anyway.

I tried all the way either cmd /writeroomfile or Universal Extractor tools or even PhoenixTool 2.73 latest version. None of them extracting any off these Dell bios files

is there any other tools are available? or not possible

@superb123 - You need to use AMIUCP. 1.07 is latest I know of, PM me if you can't find and I will find you a link
"R00" is the rom, select it, hit extract, pick file name, then apply. This applies to both BIOS you mentioned above

Hello PMed thank you

anyway after modified the extracted rom files,how do I return them back to exe file where it will flash like normal?

@superb123 - You cannot do that, well you can, via the same application, but flashing will likely/usually fail.
Mod BIOS needs flashed other way, such as programmer, FPT if Intel System, Flashrom possibly, or Dell programs such as Dell Client Configuration Utility (DCCU) or Dell Command-Configure)

By the way - if you want, that Lost_N_BIOS gets notified about your post, you should use the direct addressing feature of the Forum (here: "@Lost_N_BIOS").

@superb123:
No mainboard BIOS, which is delivered by the MB manufacturer, contains a BIOS modding tool. The offered BIOS packages may only contain a tool or EXE file to get the (original) BIOS flashed.

@superb123 - What you are extracting is the entire BIOS rom/bin, this is not HDR. After checking, these are not HDR/PFS on both 8930 and Aurora R9, not sure what this format would be called, or how to edit it like this.
In this format it cannot be properly modified for a normal BIOS mod, nor can it be programmed in with programmer, so toss this and go about what you want in a different way (ie dump BIOS, then edit, then flash/program back)

If you are looking for "Setup" module inside that BIOS, it would be in the main DXE volume, which you can usually find with MMTool or UEFITool etc.
But, AMIBCP has nothing to do with editing "Setup", unless you are going to change the name of a menu item, then it would update setup module.
Also, sounds like you may not be using correct AMIBCP, or AMIBCP is not compatible with that BIOS or the file in it's current format (It's this!), or you may have to use a modified AMIBCP
I would not use AMIBCP to edit this BIOS, generally speaking I don't use AMIBCP for any edits, other than to change a menu's name sometimes.
I do all edits manually, but if you want me to check if AMIBCP breaks this BIOS, or what's version is compatible, please tell me what model. to check.

Honestly, the way you are talking about stuff, it sounds like you are looking to do something without any guidance, and may end up bricking the machine, if you can even flash in the modified BIOS.
It may be best for you to ask for a mod BIOS instead

OK, I checked both BIOS you mentioned above, both extracts are non-standard formats (not PFS/HDR), and neither can/should be edited with AMIBCP.
And, neither contain setup module in a manner you can edit in these files as-is. You'll need to dump the BIOS off the motherboard, then edit that, and flash/program back. Are these AMD or Intel systems?
If Intel, use FPT, and dump as noted below for each, send me the file created at step #1 for each, and then tell me what error you get at step #2 for each, and then I can tell you how to proceed after you edit

I know 8930 can be dumped/edited in this manner, due to helping another user with this model here - [REQUEST] Unlock options and Remove Dell SupportAssist detection from Dell XPS 8930 bios *** See below
But for Aurora R9 I can't find any thread here, or a dump/bin online, so I can't check it to answer further until you send a dump.

*** Also, please note, at the above thread for 8930, we found Intel Boot Guard enabled at the PCH, so assume yours is as well (read - IT IS), so no BIOS settings changes can be made in normal mod BIOS manner (ie edit of setup, or AMITSE, nor use of AMIBCP) or = brick!
The only thing you can do on this BIOS in regards to settings, is to change the actual current applied value of any setting (hidden or visible) via NVRAM edit using grub/setup_var or RU method, NVRAM is not covered by boot guard.

@Lost_N_BIOS
I will reply the result when i getting back to those dell pcs, thanks
