Hi, no worries, I understand how tricky this must be to get right without having the Board available, I do appreciate all the effort your putting in!

Its good of you to help in the first place, I'd have no way of getting this working myself !!

I naively thought that these PCIE to Dual / Quad M2 NVME adapters would just work, I only found out about this Bifurcation thing, once I googled after plugging it in and only one of the two SSD showed up, it's an x79 board, so in theory supports it, I do wonder why these options were disabled and Hidden in the BIOS in the first place.

User v1 BIOS -> doesn't allow me to enter the Overclock Menu
Super v1 BIOS -> doesn't allow me to enter the Overclock Menu
User v2 BIOS -> doesn't allow me to enter the Overclock Menu
Super V2 BIOS -> doesn't allow me to enter the Overclock Menu

And annoyingly M-Flash on this board only picks up file names that match the original BIOS naming, so was a bit of back and forth to flash and test each one but results are above.

But none of them allow me into the Overclock menu you have added.

Thanks.

@ipdialup - Yes, kinds tricky when I can test right here and then send to you, AND MSI is one of the more tricky to get sometimes too
Thanks for the heads up about the name, sorry about that, I'll start putting back into folders instead

So, when you try to enter, on any of those previous, does the BIOS lock and you have to CTRL-ALT-Del to reboot, or can you carry on in BIOS just no entry to Overclocking?
I looked over the major edit part of what I did, and all looks correct there. So, this non-entry is left down to permission, or magic string, which is used in this BIOS and I originally didn't touch magic string because it all looked correct to allow entry into all by default.
So, added one more 01/yes in case that's the issue here, if this works then it's odd (MSI For ya) and magic string is out of order.
Quick test here - https://ufile.io/k1yi705d

Actually, here, similar edit w/ +2 more and +1 added in other direction in case it's backwards or XMP menu entries are counted etc

Hi,

I have tried these two, again same behaviour, the BIOS doesn't crash, just when I select the "Overclocking" menu and press return or click on it with the mouse, nothing happens.

Mouse cursor just blinks once, then I can continue to other settings etc..

Thanks.

@ipdialup - Thanks for results and info, something out of the ordinary must be blocking it then, I'll deep dive and see if I can find it!
If I can't find what's blocking that, I'll just redo this edit to put IOH submenu itself there instead of the entire hidden OC section, that would not be blocked like a whole hidden main menu section could be, so should show up right away.

* Edit - @ipdialup - How about now, can you enter IOH Config - http://s000.tinyupload.com/index.php?fil...475436127216298

Hi,

Just tried this BIOS now, and the menu has changed to IOH, but I still can't seem to enter the new menu as before, nothing happens when I attempt to access the submenu.

Andy.

@ipdialup - WTH is going on here, wow, never had such issues with this kind of mod, crazy!!!!
Here, try both of these and let me know if you can enter w/ either now - http://s000.tinyupload.com/index.php?fil...196151983425451

Ok,

Tried with both Super & User BIOS'es same behaviour still can't enter the IOH menu....

Thanks.

Hmm!!! Give me some time to look it over again, there must be something I'm overlooking, can't see how though since I've checked it so many times and reworked it for the IOH instead edit.
Sorry for the hassles here, normally this is a very simple edit once I gather all the data and do the edit!

Hey, no worries, see what you can sort, worse case I'll have to get two discrete single NVME PCIE cards and stick the video card into a 1x slot, it's a server machine so no need for decent GPU performance :-)

Hope you can figure it out, it's almost as though anything that is in that Hidden Overclock MENU area is locked out via some other mechanism other than the User / Super user permissions.

Hopefully I can get for you, I hate letting BIOS win!
Yes, it does seem like something is locking us out, but generally that's true for any similar edit I do like this, and usually no problems (two examples below, I keep link of these handy for reference since I gave users how-to notes)
But, I've done this same kind of edit for many other boards too, these are just the ones I keep in my notes in case I need to link someone to method or double check something etc

Move (copy) a Menu (aptio IV)
msi z97 pcmate unlocking advanced and chipset menu (2)
See also, non MSI, Aptio V example here - [OFFER] Gigabyte GA-Z370-Aorus Gaming 7 BIOS mod (16)

Quick general summary of method = Swap Submenu
@AMITSE/SetupData (Body) - Element Edit/swap >>
x18 word - Destination PageID >> SWAP
x1C word - Menu Visible or not = (access level AMIBCP - Edit if needed)
X20 Help label ID >> Swap
x3C Item Label ID >> Swap

@Setup PE32 or other subGUID (AS-IS) Edit >>
Label ID >> Swap
Help Label ID >> Swap
Form ID >> Swap

And for your reference, in case you are interested, here's my messy working notes for this edit on your BIOS so far

Hi, I will test these latest updates and get back to you.

On the NVME card, yes I have one of these

https://www.ebay.co.uk/itm/ANM22PE08-NVM...872.m2749.l2649

ANM22PE08 NVME PCIe 3.0 x8 Dual Port Card.

Currently has 2x500GB Toshiba XG5 drives in it, but only one shows in windows.

Thanks.

@ipdialup - I have an idea, if the above BIOS don't work! We should test replacing this item, with some submenu you can already see by default in another section, and then see if same lockout or not.
If it is, then I'm missing something, or something additional in the element needs swapped in this BIOS that didn't in other Aptio IV/V that I've done before

Hi, sorry been slammed with Work & Home life over last couple of days haven't had a chance to go through these, will try to do it tonight.

Thanks.

Never a rush here, I'm always behind, so no worries, whenever you get there we'll carry on with more test edits

Hi, I came across this old thread and figured i'd say hi as i also need a bifurcation bios for my trusty old board. Thank you for your wonderful work so far! I have tested all your last 3 posts in this thread with no success, unfortunately. The BIOS you posted has all features enabled and all menus functioning as far as i can tell. There is an extra menu under advanced called "IOH configuration". I cannot seem to open in either of the three biosses you have submitted here. I would love to be of service for further testing if you are still up for the challenge. Looking forward to hearing from you.

I am using a 4-way adapter and would like the middle x16 slot divided into x4x4x4x4 if at all possible.
