@Lost_N_BIOS
Thank you so much for this huge work! I really appreciate it.

Well, my board has bios from 2017, yes. Not sure how did it get that bios (probably from Asus factory), but nearly 100% sure this is original Asus, what makes me thinking if there is any mistake this is their mistake. I previously had Asus ROG mobo which bricked because of their official bios. I went with it to the service, they didn`t believe me, removed bios chip, flashed it to a default version, and bricked themselves again with the latest official version of Bios. So no surprises with their Bios quality :)

Prior I will flash to the newer bios, may you please let me know if I will be able to move between version freely after that? I saw a warning message somewhere here that having latest versions on Asus there is no way back without programmer (which I haven`t even order yet).

@ZAC - You're welcome!

Probably Asus posted that BIOS long ago, and then later at some time after you downloaded it the y fixed the FIT table and reposted it with same version info etc.
Yes, it's their mistake if you never flashed mod BIOS, I see it from time to time on manufacturer BIOS, they either fix later and repost same link, or leave and fix on next version. That's funny about them bricking it with their own BIOS

I don't know about BIOS version going back and forth, but often you can't due to ME security locks, this only applies to official method (EZ Flash). You can flash back any time you want to whatever BIOS region via FPT, so no worries there.
The BIOS I posted above is same version I gave you before, only your edited backup dump with the changes I mentioned. So you'll still be on that same version if you don't want to update now it's OK you can stay on that one.

@Lost_N_BIOS

Yep, Asus later replaced the bricking bios with another one having same version and name. But since that I prefer to not update anything without a real reason :)

I flashed the second edition. Yes, I see the Raid option now and able to select it. Although, I have no idea what to do next to use it. Usually, if Raid is enabled you have the second boot menu after the main Bios. It shows you keys to press, like Ctrl+O, and after pressing them you open Raid config utility. Here I see nothing has changed after setting the Raid enabled in Bios. I am not sure how it supposed to work on this mobo, but watching this video https://www.youtube.com/watch?v=Z7XpK-5WgLU from similar motherboard (probably on the nearly same Bios) I see Intel Rapid Storage Technology in the center of Bios home page, which I don`t have. Is there any chance to enable it too? Also, in this video they have another EZ Tuning.

I am attaching DRAM settings screenshots. Yes, I did reset Bios settings, but the only one which lost ability to select offset is DRAM Voltage. Anyway, it is not a big deal as I can use manual setup even though it is not present in visible options.

The main thing about memory is to enable Reg support, no matter on what voltage it will happen.

@ZAC - Manufacturers often do that if they find an issue soon after release, try to do it quietly which is bad because then users might not notice there's an issue with BIOS they're already using. Bad form!

Let me look at BIOS more, you may need other option enabled to allow the Control+I menu option for the RAID config menu. I did not watch video, sorry limited bandwidth, but EZ Tuning?
If you mean screen that shows fans and simply GUI click type BIOS, if yes, no that's only for other models, I can't add that. Most people instantly hit F7 to get out of that to go to the BIOS you have anyway

I put back the dram change in this last BIOS, meaning I did not enable SPD Write option this time, that was the only change I made their before. ECC support is already enabled by default
For dram offset voltage you have to change from Auto to + or - then enter a value, this is normal way it works if you are using offset setting instead of manual.
In your BIOS, I do not see offset option for DRAM, only direct voltage value input, this is on the stock BIOS, so you may be thinking of vcore, turbo voltage, or other setting you were using offset on previously, it's not normally a way to set DRAM voltage anyway so I'm not surprised to see this.
Flash back your original FPT backup, then you will be back at square one, and you'll see this was not ever an option for DRAM voltage.

Now, if you want BIOS with lots more options on the memory page, so you can see/change ECC setting I can do for you.

On the RAID, I checked and RST roms are already there 15.2 EFI and orom version (Was thinking maybe these were missing), so it's not that why you can't enter control+I. You did try Control+I at bootup correct, not Control+O as you mentioned
Can you show me image of all the settings you can see inside >> Advanced >> PCH Storage Configuration >> Software Feature Mask Configuration Orom and UI banner is already enabled, this is what allows you to enter Control+I option (it's enabled with only 2 second delay so maybe you missed it at startup?)

@Lost_N_BIOS

Thanks.
By some crazy luck I have 8gb ECC memory module. Now I have a standard stick, ECC stick, and ECC Reg 3 sticks. I expected to see some memory settings for ECC specifically, but haven`t noticed anything new. May be now this is stuck in cpu support of ECC memory, just a wild guess. Please, unlock everything related to memory.

I did try Control+I, nothing happened. Everything under Advanced >> PCH Storage Configuration is below

Should I go for the latest official bios version prior you will add any changes to my old version?

@ZAC - I'll unlock everything memory related, but before I do that, can you ZIP all images for settings you can currently see that are memory related in any section. (Unless it's all above in post #18, if so then I got it already)
Do you have Advanced >> System Agent Config >> memory config (And it's submenus), or all memory related settings you have are all located in Ai tweaker only?

If you want to update to latest BIOS, please do that using official method, and then send me a new FPT dump. I thought you were already on latest BIOS, sorry for letting us continue this on old BIOS, I should have asked initially for you to update if you wanted to before we got started.
I'm not sure if there are any ECC specific settings, I only know there is ECC support enable/disable, but yes there are tons of hidden settings so possibly some of those you were looking for.
Please also add an image of the root page of Advanced, so I can see all the subsections inside there that you currently have visible.

@Lost_N_BIOS

I can see Advanced >> System Agent >> Memory Config, but the only available setting there is Memory Remap.

Looks like I have only a few voltage settings in addition to what you have mentioned. This is all about memory setup in the bios version 2604.

https://ibb.co/LvZ43xV

And here the new dump itself.

ECC may be named as parity check or error correction, not sure. What is more important is Reg (registered) memory settings. Anyway, I`ll be glad to check all of them. Thank you in advance!

@ZAC - Thanks for the image, info, and new dump. ECC is named ECC in the BIOS, but other settings below that may be some of what you were looking for, not sure?
FIT table is broken again in your 2604 dump! Was this updated from previous stock BIOS, not a BIOS I fixed this already for you?

Here, in this BIOS, RAID is enabled (already set) on 0-3 controllers, outside of your BIOS options (unsure what these are, but thought maybe that's why you weren't getting RAID enabled previously).
If it fails to load any disk due to RAID enabled how I mentioned reflash other BIOS and let me know, I will undue those changes.
That one setting "SATA Mode" I enabled for you is left at default (AHCI), test BIOS for RAID without changing that, and then if still no luck change that to RAID and check again. It's possible due to new changes I mentioned, it may be locked to RAID always now (If it is, we'll figure it out)
I also extended the default time to 4 seconds for Control+I entry, this option will be visible to you so you can change later. Also re-corrected the CPU microcode _FIT_ table again

@Lost_N_BIOS

It was their latest official bios
https://www.asus.com/Motherboards/B150-P.../HelpDesk_BIOS/

What if FIT table is not broken, but has a signature or some intended modifications?

Thank you for the bios. I see many new options for memory and raid. But the raid menu still does not appear no matter what I press. Perhaps, AHCI should be changed to Raid? I don`t have the RAID option here in this bios. Could youlease, enable it?
There are many raid options in newly appeared Software menu. Even though they are enabled, they don`t work yet.

ECC memory works, but seems settings are auto adjustable. At lest their changes are not shown on bios exit screen.

@ZAC - It's going into your board incorrectly for some reason, I already checked stock and it's not broken. There is no signature or anything for this, and your case is only one I've ever seen do this, maybe something with this specific model or some other issues causing that on your end?

Yes, now please test changing AHCI to RAID and then test again. Did you mean now you can't see Advanced >>> PCH Storage Config >> SATA Mode Selection? If not, can you see Advanced >>> PCH Storage Config submenu?
I may need to undue the "hidden/off menu" RAID settings I mentioned, that may be causing the SATA mode Selection option to disappear from your view, even though I already set to be visible again? But before, these were set to AHCI, and you could still see SATA Mode Selection, maybe I need to set that to RAID to match, then you can see?
If so, then you may not be able to change it back to AHCI. Would you be OK to test a RAID only enabled BIOS for a second so we can figure that out? If yes, I will make for you tonight a BIOS with those changes, and then another with removed RAID on those hidden ones I mentioned.

@Lost_N_BIOS

Wow, I didn`t know that such bios issues are possible. Not sure what to do with it knowing that. I hope direct flashing the bios chip might help, but Chinese $5 programmer doesn`t work in 64-bit environment. At least those which I found.

Yes, CH341A works fine in X64, 1000's of people use them every day! And it's cheap $2.50 programmers not $5, yes they work fine in x64

Ohh! OK, thanks for clarification about Setting is there, but no RAID choice, I probably forget to unsuppress that again after you sent new dump! Sorry, will redo this right now and unsuppress that!
My other thoughts there at end, about two BIOS may not be needed, I was confused on what you meant regarding this setting. We still may need to do that later, but for now I think not.
If you're reading this, refresh page in a few minutes for edited in BIOS with unsuppressed RAID Option at SATA Mode Selection I can't believe I forgot to do that again!

@ZAC - Here is fixed BIOS, should have RAID Option now on SATA Mode Selection setting!

@Lost_N_BIOS

Thank you for your time.

I definitely will order CH341A.

I see the Raid option now. But still, there is no menu, nothing shows after Control+I or Control+O. I tried all hdd settings there, no effect. I am not sure what else to try.

If this relates my damaged bios, should I try to flash it with Version 11.8.55.3510 as this is the latest here? https://www.asus.com/Motherboards/B150-P.../HelpDesk_BIOS/

@ZAC - You're welcome, and thanks for confirming RAID choice is back, sorry to hear it's still not working.

Your BIOS is not damaged, it's just odd that even after you keep reflashing corrected FIT table it dumps with it broken again. This only affects CPU microcode loading, nothing to do with Intel ME.
Despite the numerous posts and articles around the web, new and old, about B150 chipsets and B150 motherboards, the chipset itself supports RAID (Says Intel in one place, but not another?) but many motherboards with it do not.
There may be some missing hardware on the board to enable it's functionality, tiny resistor here or there? Or maybe we need to put in some updated RAID roms? Hard to say
https://www.intel.com/content/www/us/en/...psets/b150.html = RST=Yes
https://www.intel.com/content/dam/www/pu...sheet-vol-1.pdf (232-242), but page 21 saying no RAID contradicts Intel spec sheet on first link (RST = Yes). Sounds like from this PDF, it's only possible on the workstations/chipsets

So, from the Intel PDF, looks like this is not possible due to the chipset itself, sorry for not looking this up sooner

@Lost_N_BIOS

No worries. I knew it is not officially supported, but c`mon, we are here to unlock what is hidden:)

The same no luck with Reg memory support. Maybe, you can unlock something about buffered memory? Fully Buffered DIMM (FB-DIMM)?
