I have Dell Optiplex 7040MT ready in my side this is why I sent you Bios for it.
Regarding Dell 3046/5040, I will make a backup once I receive it.

Thank you
Salim

I see, thanks for explaining. What CPU's will you use on the Dell? Or what exact CPUID's do you need as part of the mod process?

Dell Optiplex 7040MT can only use 6th Gen CPU.
I want to update it to use 6th and 7th Gen.
I can use Tray or Box CPU.
I think we can use the same like HP AIO model.

Thank you
Salim

What CPU's though, or what CPUID's, there is too many CPU's to say make entire 7th generation compatible, pick some you will use and give me CPUID's

Please run MEinfowin on the Dell and show full image of output, thanks! This BIOS has bootguard/ACM, we need to see if it's active, microcode is inside cyan region so if bootguard is active any BIOS mod may brick no matter what.

Hi

This Dell 7040MT have a Jumper and when we short it ME region is set to Disable.
Does this mean anything for you or can help us.

Here is MEInfoWin file you asked for,

Please Note that I used MEInfoWin with ME Enable and I didnt SHORT Jumper.

I can make a BIOS BACKUP if you want me to do it again for you.


Thank you

Here is a file which i want to share it with you.

I think it is good for you

Goodluck

Thanks for the meinfo, checking into that now. I don't need another backup, ME was enabled and that's what I needed. Thanks for PDF too, will check it out

*Edit - checked on this, bootguard is not setup correctly, thus not enabled, so it's a go on editing BIOS for this system!
Once the other Dell's arrive, run meinfowin on them too, and when you send their dumps package up their MEinfowin images in the zips so I can check those too.

*Edit 2 - @simoutekd - Please test on Dell, ME change only right now, then next step microcodes + ME

Any progress on HP's diagnosing? Have you tested with secondary BIOS removed?
Did you look on board and see if you can find third flash block that possibly contains the HP Trust thing? If you think you find, dump the chip and we'll see if we can verify/identify contents

Hello

Dell Optiplex 700MT system still in Manufacturing Mode Programming State. I can commite it to Normal State just by adding TAG number then I can DUMP BIOS Again.

Regarding HP All-in-One still didnt try it but i will do that on Saturday. First I need to know how to Block SureStart from HP BIOS then move with that.
I learned from PDF file that when in Surestart manual activated and after system power on, document said that i need to push Power ON Twice in less than 2 SEC to display details on screen. I will do that.

Thank you
Salim

You can leave in manufacturing mode probably, and still test BIOS, then put back when done testing, or finalize once we're done.

There is no block surestart from BIOS, only remove surestart function. That is why I wanted two thing I mentioned, test without secondary BIOS, does recovery happen still, and then find other flash rom chip which contains surestart coding/data etc.
It's on a flash rom somewhere, we probably need to remove this and secondary BIOS for system to be how you want in the end.

Found another PDF - http://www8.hp.com/h20195/v2/GetPDF.aspx/4AA7-2197ENW.pdf
Firmware resides in a non-volatile memory on the circuit board and can’t be removed simply by erasing the hard drive. *Wink * Wink *Hint *Hint - they didn't say you can't simply remove the NVRAM (Flash-rom)

Also, see this, maybe you can download this and see what options are given this way too -
Manageability—Administrators can manage HP Sure Start capabilities with the Manageability Integration Kit (MIK) plugin for Microsoft® System Center Confguration Manager (SCCM)
https://www8.hp.com/us/en/ads/clientmanagement/overview.html

And, in the F10 BIOS menu, options for sure start, did you check to see if "BIOS Data Recovery Policy" can be set to disabled, or only auto/manual?

This makes it sounds like disable is possible maybe "Enhanced HP Firmware Runtime Intrusion Prevention and Detection - The RTID feature can be optionally be set to disable by the platform owner/administrator"
Maybe that only covers part of the BIOS code?

Get me some good clean images of one of these boards, in full, so I can pick and point chips for you to try and dump.

Hello

Today I updated my Dell Bios with your File and everything worked correctly for me.

My Computer started normally and here is a copy of MeInfoWin File.

Check it please.

Regarding HP I will check it and let you know the news.

Thank you
Salim

@simoutekd - Good all went smooth so far, thanks for update! Here is new Dell BIOS with ME + Microcode added for other CPU (and FIT table expanded and corrected), but don't test other CPU yet, no vBIOS edit

Hi

I tried to use you NEW file with CPU MC changed but I am sorry it is not working.

I am getting this error:
Power Light: Amber Blinking
2,3 : 2 blinks followed by a short pause, 3 blinks, long pause, then repeats
Bad Motherboard, Memory or Processor
If you can assist to troubleshoot, narrow down the issue by reseating memory and swapping a known good memory if available.
If nothing works, replace the motherboard, memory or processor.

This is the link for Dell Optiplex series Bios errors.
https://www.dell.com/support/article/us/...2012_to_Present

I think the best wqy to deal with this is to change All in 1 time and try first then see what we get.
That mean we change CPU MC; VBIOS; GOP all.

What do you think
