@Lost_N_BIOS on the subject of jumpers, I noticed there is one named "BIOS RCVR".
While all the rest are documented - these BIOS jumpers are not!





Do you think if I set it this will make the board magically recover BIOS to the "factory" F01 it had ???
I do not think this board has dual-BIOS like other Gigabyte boards. What might be the purpose of this jumper? Very tempting to try...:-)) worst case I just flash with the broken F06 again? lol

So @Mekw I gather you didn't make a BIOS backup before flashing either? Yes, I will help, once I figure this out, too bad there is no GbE, we'd be done by now! Do either of you guys know anyone else that owns this model, even online friend you could contact?
If yes, please message them and show them how to get a dump created with FPT and ask them to include at least one of their MAC address if not both, this will help me be able to fix your MAC Addresses for you.
I may be able to figure it out anyway, but a dump with valid and known MAC Addresses in it would really speed up the process

You both should try to ask Datto if they have a tool to reprogram the MAC ID's, or ask for their specific default location in the BIOS (What module is it stored in, or what hex address, either would be helpful).
If not, hopefully Gigabyte will reply eventually, if they do ask them these same things, maybe update your tickets to them too and tell them you can fix manually you just need to know where to put the address (Tell them you don't need to know how, just where).

In the meantime I will take a long look through the BIOS and see if I can find the location. What is the LAN chip in these boards?
This usually holds one LAN MAC ID, but only for the PXE Booting from LAN thing, not really the two MAC ID's we need to fix, but I'd like to check this module in case it possibly holds anything helpful

@dimadima - that may work, or it may work like a BIOS flash, and purposefully leave your current LAN ID In tact like a normal BIOS flash would do usually. It's something you can try, there is a secondary BIOS chip on the board most likely.

Do either of you have CH341A or other flash programmers and SOIC8 test clip cables (If soldered on BIOS)? If yes, then whoever does have programmer could go ahead and try out the recovery jumper and see what happens, then if it's bad outcome you can put back the FPT dump if needed.

If you do get back to that F01 BIOS, send a dump for comparison. I doubt it will fix the LAN, but you might get lucky.

That looks like Gigabyte board to me, but it's hard to say exact model that it could be, if all same as what you guys though when you picked this BIOS to flash or not vs board revisions and updates etc.
I know the manuals are always old, often written using pre-production boards too, so that not matching up exact is expected even if you purchased official board from Gigabyte.

@Lost_N_BIOS i do NOT have any flash programmers. Are you saying in this case i should NOT try the "BIOS RCVR" jumper?

It's up to you, may not be good outcome since you flashed in other BIOS. If this is your only system I would wait and not do it until you have programmer in hand, if you have another system you can use in mean time while you wait on a programmer to arrive then go ahead.
It would probably be OK and recover, to old BIOS with zero LAN still, but best to have programmer ready in your hand just in case, especially if this is critical use system. You can get programmer quicker than 3-5 weeks from china usually, but it costs more buying locally or from seller that offers faster shipping options.
You need CH341A ($2.50 on ebay) and if BIOS is soldered to board also need SOIC8 test clip cable ($3.50 on ebay), or a kit like EZP2010 or EZP2013

*Edit - did you guys see last post here yet? Maybe some of them are your posts?

Looks like by flashing a different BIOS, they were able to get correct LAN ID's to show in BIOS. With this, you can dump via FPT again, I can find where those are stored, and then fix in original BIOS then you can reflash that one again.

Poor chap on the other thread. Unfortunately the DS4 is a no go for me as I don't have the 10g NICs on my motherboard.

@Lost_N_BIOS - According the manual - 2 x GbE LAN ports (Intel® I210). Again I'm a little skeptical on this as it was getting these working with ESXi that prompted to me flash in the first place as they were being discovered as 10g X557 Nics, which the firmware apparently removes.

I'll take the risk with recover and report back @dimadima if the damn jumper doesn't disintegrate :-)

Ohh, I didn't think they had correct hardware either, I thought it was this same board. You can use jumper off another board if yours breaks

Well I don't think he's particularly clear on that thread. Might be worth a shot, since we're clutching at straws. I am wondering because its got IPMI to flash motherboards whether that element is seperate anyway and if i were to brick it, it would be still recoverable via the IPMI BIOS Update.

Anyways back on point:
Recover option - no go for me. I get ROM Image is not loaded, ROM Image Update Denied.

@Mekw thanks for being brave and trying the BIOS RCVR jumper. I guess it’s only putting the mobo into the “ready to accept flashing” state...

I had high hopes for it as the ME RCVR jumper apparently does the magic of restoring the factory ME if to trust the scarce documentation.

Ok so interesting slapped the DS4 firmware on (yeah I'm gun ho) and got two MAC Addresses against LAN1 and LAN2. Now to see whether these are the ones I want.

@dimadima
Short answer: Flashed with DS4 Firmware, and I've now got networking in Windows 10 after installing the Intel drivers. Which is really really weird...

Why you ask? Because its still stating these are 10GBASE-T X552/X557 NICs.

So the reason why this screwed up in the first place, is because the DS1 firmware removes these NICS supposedly leaving you with the i210's.

I am soooo confused that my head hurts.

Going to back and try ESX server now, maybe instead of asking why its reporting the wrong NIC, i should be concentrating on why its saying media disconnected in ESX.

@Mekw
OMG - you got it working?! I had to re-read it a few times and pinch myself I was not dreaming.

Are you saying this Datto board has 2x 10 Gig LAN instead? After all they are in that place on the motherboard where the 10G SFP is (on the more expensive board version).

I might start looking at used 10G switches then!! Lol

I cannot get my head around it, the DS4 has:
2 x 10GbE SFP+ LAN ports (Intel® X552)
2 x GbE LAN ports (Intel® I210)

And the Datto board would have 2x 10G X552 with the only difference being BASE-T / RJ45 and not SFP ?!

Correct. Remember its an OEM board, does not have to match the specs. Basically we were told its a MB10-DS .. and its not.

So yeah I'm working at present (well in Win 10). Not done anything major with it, other than slap a ping and make sure its responding.

Also found an auction site with the unit our motherboard is from, it states its an X552/7 and no mention of the 1gb nics. Oh and the backplate picture matches ours exactly.
So basically we were barking up the wrong tree.

Send me a dump from the crossflashed DS4 board/BIOS combo that has working LAN, and include BIOS images of the LAN Info too, thanks. This should help me find the location of the MAC ID's, so I can fix the normal BIOS for you guys.
