@Hai kkk - Please zip for me one image of all your current BIOS main sections (Main, advanced, boot, exit etc), and in advanced and boot, scroll up/down if needed and show me all contents you can see

@akm - Yes, sorry I didn't check that setup IFR before I sent to you Thanks for list, I will get into that tonight for you
So, you didn't need anything changed in PBS or CBS? If not, then all I need is simple/single list of what you want changed in setup (I have not looked at your file, just replying this to your comments)
* Edit, I checked your file, WOW, that is a lot of changes You'll have to give me some time to do all that

---

@akm - sorry, that list was so huge, I think it scared me off and I forgot about this , tab was open though so I did mean to get on it
No, there is no spread spectrum BIOS setting. Please pick a single setting that is enabled or disabled by default, that you wanted opposite of, so I can make you a quick test BIOS to see if I have to edit in two places for each thing you wanted, or only one place.
Sorry for the delay!

@akm - Thanks! Yes, it is quite the list of changes
Yes, you will need to flash two mod BIOS, to see that the default changed or not, and I need to know answer from each BIOS.
So you can see HPET setting in BIOS now? If not, pick something else, that you can see setting in BIOS, soyou can see if default is changed once you flash the two new test mod BIOS

Yes, we can change settings without BIOS mod, and this will be easier for me too >> Please download the following package, and run the command below from each versions folder that directly contains it's exe.
Once done, copy the entire folder somewhere, delete everything but any created vars.txt and then repackage this and send to me, this way all created vars.txt remain in place in the folders of the version that created them.

@Lost_N_BIOS Actually, I already shared the dumped vars files in this post.

In that post, I also reported that I tried the BIOS dump method using the flashrom utlity (you provided). The process failed. So, I am concerned that the BIOS flashing process may be risky. But, anyway, you are the expert, and I will just follow your instructions.

In reply to that post, you said that "we can change any of these directly without a BIOS mod using vars or RU method". I too would prefer that.

By the way, HPET is not a visible setting in the BIOS. But it shows up in Device Manager in Windows. If HPET gets disabled, I will come to know from the Device Manager. Anyway, if I needed to choose a setting that is already available in the BIOS, I would go for "PowerNow! Enable". By default it is enabled.

Thanks!

@akm - BIOS flashing is only an option once you have flash programmer, since flashrom method does not work for you.
Device manager is not a way to see if HPET is disabled or not. As mentioned, please pick another setting in your list of desired changes, that you can actually see in the BIOS (so you know it's default, and what you always change it to)
But, I guess never mind on that, since for now we'll have to wait on actual BIOS mod until your SOIC8 test clip/cable arrives, before I'd need to know results from the test BIOS I mentioned above that required you choosing a setting like this.

So, for now, all we can do for now is change settings in vars, or you can do with RU, which would be very tedious for you, since you will be changing all that one by one too, while looking at unfamiliar info for each setting
Please give me a while to do all that I'll get started on it now, but it may take a day or two, especially since all those "Setup" changes are not in usual IFR format AND have to be done twice in Vars

* Edit @akm - Just FYI >>
30. (0x4F, 1, 0xBC80C5DB3DE40618, 0x1648) NB Azalia -> Enabled (because I want it force enabled) << not possible to "Change Default" without BIOS Mod, only possible to "Change Current Value"
31. (0x50, 1, 0xBC80C5DB3DE40618, 0x168C) IOMMU -> Disabled >> Already Disabled by default
32. (0x60, 1, 0xBC80C5DB3DE40618, 0x1A1C) SATA Controller -> Enabled (because I want it force enabled) << not possible to "Change Default" without BIOS Mod, only possible to "Change Current Value"

@akm - See edit above Almost done, 5 more items to set x2 (so 10 more bytes to change and I'll be done )
You're welcome!
----------------

@akm - Additionally, these two cannot be changed possibly, due to they have the same offset and are located within the same varstore ID


So, other than BIOS mod cannot be changed in this manner possibly, only by question ID edit which we can't do here
13. (0xEB, 1, 0xB07398139D839CF0, 0xCB) PowerNow! Enable -> Disabled >> Issue *
16. (0xEB, 1, 0xB07398139D839CF0, 0x282) Cool N' Quiet Support -> Disabled >> Issue *

I set 0xEB to disabled, but not sure if it will disable both by this kind of edit or not, or which will be disabled etc

Additionally >>
19. (0x65, 1, 0xB07398139D839CF0, 0x8C9) UEFI OS Fast Boot -> Disabled << already disabled

Here is modified vars, drop this into H20UVE_100.00.16.08 folder, then run the following command >> H2OUVE.exe -sv varsM.txt
http://s000.tinyupload.com/index.php?fil...934371828129329

You will see a list of success/failure, we made changes at the following, if any of those fail, then those settings set at those areas cannot be applied in this manner either (need mod BIOS to make the live/current change)
00A
00C
00D
04B
07E
07F

This kind of edit ONLY changes the live/current applied setting values

@Lost_N_BIOS Thank you so much! :)

If 'PowerNow! Enable', 'Cool N' Quiet Support' and 'UEFI OS Fast Boot' cannot be disabled, I think I can live with that. So, I have no concerns here.


I ran the command and saw that most of the changes were successful, but some were unsuccessful. The unsuccessful ones are:

Variable Indices:

001, 002, 003, 004, 006, 00f, 010, 01d, 01e, 045, 080 and 081.

I have also shared the screenshots of the success/fail messages that appeared after the command was run, here.

Unfortunately, HPET did not get disabled (I believe it is one of the above). If we can't modify the remaining settings without BIOS mod, I can manage with the current state, but I really wanted to disable HPET. I was wondering if there is some way to successfully disable HPET, besides the BIOS mod method. Please confirm.

Thanks again!

@akm - You're welcome!! I set the variable for 'PowerNow! Enable', 'Cool N' Quiet Support' to disabled, and 'UEFI OS Fast Boot was already disabled, so it's all disabled

All changes were flashed in successfully then, if those you gave above are the only ones that failed, since we only changed items in the following
00A, 00C, 00D, 04B, 07E, 07F - Yes, confirmed all these were set successfully in your images, so all changes made were flashed in without issue

HPET would be disabled if it was one of the changes you gave me to disable. I checked, it was, and flashed in successfully.
How are you checking that it's not disabled? Device manager is not how you check that, on Win10 it would always be there if OS was installed while HPET was enabled (or maybe always, not sure)
See my testing on this in following thread, see change log for HPET comments and testing results of BIOS enabled/disabled HPET + OS side HPET Disable with BIOS enable/disable
[OFFER] Gigabyte Z390 M Gaming UPD + Completely Revised Blue Theme

In that thread, I mention how to disable from OS side, but I suggest against that (you can also uninstall now from device manager if you wanted, since it's disabled, but I also suggest against this)
If you feel you must disable on OS side, do the BCDedit change instead, then reboot.

@Lost_N_BIOS I think you are right about the HPET. Upon further testing, it seems to be disabled even though it shows up in Device Manager. Interestingly, on my other two laptops, upon disabling HPET from the BIOS, it stops appearing in Device Manager then.

Just wanted to confirm that the settings changes which we have applied, will stick until I reset the BIOS (by loading the optimized defaults), right? If I make any settings changes in the BIOS menu, will that affect any of the changes applied through your method? In case of any confusion, if I reapply the changes from the varsM.txt file, it won't cause any issues. Correct?

@akm - In some older chipsets or OS, it's behavior and or how users can see it in various ways, is different than modern chipsets/OS, not sure why this is but probably due to both Intel and MS changes
Yes, all changes we mad via vars will remain unless you reflash stock BIOS, reload optimal defaults, and or yes if you change something directly in the BIOS then it will be changed
And yes, you can always reflash the mod vars, as long as you are on this BIOS version

@Lost_N_BIOS Ok. Noted with thanks. :)

@Antosha94 - Please max compress zip/rar images of ALL BIOS settings you can see currently.
Also, what BIOS are you using, or which do you want modified? There is warning about downgrade not possible - https://www.asrock.com/mb/Intel/H310CM-DVS/index.asp#BIOS
