BIOS not existing for Legacy Intel NUC D53427RKE with BIOS RKPPT10H.86F

[AWax]

Hi, my Intel NUC (details attached) BIOS cannot be updated due to lack of BIOS files on the internet

I would like to find a BIOS for my Legacy Intel NUC because MeshCommander states that the BIOS shall be updated

The issue is that there is only a BIOS for RKPPT10H.86A, just my machine has the ID RKPPT10H.86F

I would be happy if someone of you could help me since no search engine is capable of finding results for this

PS, I tried F7 Flash (not working, freezing at Waiting...) and I tried DOS Boot with the RKPPT10H.86A

If you no additional methods or maybe how to change the ID of 86A to 86F inside the .BIO file i also appreciate your help

Thanks and have a nice day

You should never get your bios from the Internet. You should go straight to the manufacturer, always.

So, here is the latest bios as of June 6, 2018:

https://downloadcenter.intel.com/download/27934/?product=74484 Download BIOS Update [RKPPT10H.86A]

And, you can always get to bios and drivers specifically for your nuc by going here, and then clicking on "downloads and software"

Save these links for future reference.

Also, I have no idea where .86F came from. Did you previously get this bios file off of the internet and install it? Perhaps N.Scott.Pearson can shed some light on this issue.

Thanks Al, for your time of answering

As you may have read I tried with the .86A already, maybe you missed this in my initial post, and maybe my language is complicated, anyway

I bought the machine used approx 2 years ago, I think I never did a BIOS upgrade yet, and this 86F is pre-installed (2013!)

"Order dispatched: Intel NUC DC53427HYE - 4GB Ram - 60GB SSD"

And now I find the same .86A image when I write the HW info from MeshCommander or the Model Number from the ebay auction into the Intel Support Search

I read also about revisions 86A and 86F inside a Post that it might be an OEM (Asset tag: To be filled by O.E.M.), lets assume another company builds a similar device like a nuc with a Board/Kit

I am close to start a HEX editor and replace 86A with 86F inside the BIO file

Intel, could you please guarantee that this will work?

Your IFLASH2 has not force option to just go ahead with the BIOS update

PS, I tried F7 Flash (not working, freezing at Waiting...) and I tried DOS Boot with the RKPPT10H.86A

it is NOT working

Any more thoughts?

[AlHill]

No, I did not miss that. That is why I specifically asked where you got the .86F.

Before you do anything, let us wait for more information.

Here's what I can tell you...

• 86F is definitely an indicator for a custom BIOS.
• You cannot replace a custom BIOS with a standard BIOS. It's a hard and fast rule and the BIOS has been specifically architected to not support this operation.
• The BIOS Id cannot be patched. Both the BIOS data (as stored in flash) and the entire contents of the .BIO file are encrypted.
• You cannot assume anything from seeing "To be filled by O.E.M." in the Asset Tag field. This is the default string that is put in all BIOS releases.
• When there is a custom BIOS in place, your only way to get an upgrade is through the vendor who purchased the custom BIOS in the first place.

Sorry, this is reality,

HI *

Cant I change the BIOS to another one? I do not think so. Never heard about something like this

Custom means that the BIOS chip is custom too? If the Hardware is different where the BIOS is stored, I would understand your argument, Is the Hardware different?

Usually Custom BIOS is revertible for example in case of DD-WRT Firmware or other BIOS-es for Mainboards

So I am sure there is a way, to change the BIOS

just maybe Intel does not share this information in public, in the test labor, I am sure they are able to change this BIOS with tools.

you may also send me a private message is this is confidential information.

For researching more about the past of the NUC, i sent an email to the seller of 2016. lets see if I get a reply by her.

Kind regards, have a good day

[n_scott_pearson]

Here's what I can tell you...

• I was able to verify that a specific customer did indeed requested this custom BIOS. I can't discuss specifics, but they required a change that could not co-exist with the standard BIOS.
• No, you can't change the BIOS. The tools necessary are simply not allowed outside of the factory (not even under NDA). Yes, technically speaking, Intel could do the changeover for you, but Intel does not offer this service.
• I do not know if any subsequent updates were released for this BIOS. You need to contact the original system supplier for this information.

Thanks anyway for describing the case, even if it does not yet solve the BIOS upgrade

Update:

on the one hand F4 (Recover)would be a different choice than F7 (Updated), maybe I can give it a try

and

on the other hand I came across this: https://www.ebay.com/itm/BIOS-CHIP-Intel-NUC-D53427RKE-board-/401378305295 BIOS CHIP: Intel NUC D53427RKE board | eBay

Opinions about those modes of succeeding in the BIOS upgrade,

There is no original vendor since i bought it used, and the person did not yet answer to me by email, maybe will never

[AWax]

Al, Scott,

F4 (Recover)would be a different choice, I found this in the internet, maybe it is true for other BIOS and other NUC, here it is not existing

so I ask if I replace the BIOS CHIP to a fresh CHIP, check the post before, it would cost 25 bucks and I would be able to solve this issue.

Please tell me what you think.

Thanks and have a nice day

With all the time and effort you have spent, and will spend, you should abandon this project and simply purchase a new nuc or device.

Having a "fresh" flash IC does you no good (and is a complete ripoff at US$25). When you install a BIOS update, it is the existing BIOS that is responsible for the installation of the BIOS update. With a fresh flash in the socket (or soldered to the board), there is no existing BIOS and the system will likely not even power on properly.

Secondly, as I said before, you cannot use a flash programmer to install a BIOS. The BIOS file is a compressed and encrypted file that cannot be opened by flash programmers; an existing (and running) BIOS is necessary to install it.

Finally, no, you cannot (or at least should not) copy the contents of the flash from another same-model NUC. Your NUC would then have the same "branding" as the NUC you copied it from. This include having the same MAC Address and the same serial number. This is never a good thing and can lead to problems for both the originator and duplicator. As I said earlier, the tools necessary to fix this are not released beyond the factory, even with an NDA, so you have no way of fixing this "branding".

Bottom line, you are stuck with the custom BIOS. Frankly, with the improvements in speed and capability, getting one of the latest NUCs would be a drastically better choice. Time is money...
