Wow, it worked great first try when flashing 50654-69.bin. Both processors detected and Prime95 burning in now. You are a legend, thank you so much!

@cmoski - Awesome to hear it, very nice!
That means this CPU is not 50654, since the 69 microcode was already in that BIOS and didn't work before. Ohh, we can tell in your info there (CPUID 6.5.2), this is 50652 as I suspected

Thank you too for the kind words, always happy to help when I can!

The link to the modified BIOS in post #9 has expired. Would someone repost, please? @cmoski @Lost_N_BIOS

@proximaldis10s - Thanks, fixed

Thanks. Can you guys point me to a tutorial for flashing the supermicro BIOS without cpu/ram present?

@proximaldis10s - You're welcome!
Sorry, I can't help with flashing without memory/CPU, you may need to find some supermicro users here and @ tag them to see if it's even possible
It may not be possible, I think that's mainly a mainstream board thing (like Asus, MSI, Gigabyte etc), and even there it's only possible on some of the more model models.
You could chat with supermicro and ask them directly, I think they have chat.

* Unless? Do you have flash programmer, like CH341A? If yes, then I can help

@Lost_N_BIOS If you're referring to one of these
https://smile.amazon.com/SMAKN-Programme...M/dp/B013Q5P3ES I'll buy one. It's immensely cheaper than finding a refurbished non-ES Xeon cpu. If not this, point me in a direction. :)

Yes, but you need a bundle/kit, so you get the cable/clip too. Like this - https://www.amazon.com/Organizer-EEPROM-...r/dp/B07V2M5MVH
BUT, before you order anything, make sure to check BIOS chip type to be sure it's SOIC8. I can't tell from board images, there's a few chips that look like SOIC16 in drop/clip-in sockets

You may need to borrow a CPU somehow, or grab one somewhere you can easily return

Ok. When I have hardware in my hands, I'll hit you up for assistance again.

What tutorials/guides should I read in the meantime ?

@proximaldis10s - Here is guide on using programmer - [GUIDE] Flash BIOS with CH341A programmer
And here is software package with driver + many software/versions, not all compatible with all chip ID's - http://s000.tinyupload.com/index.php?fil...213094641136166

So, you need to find what kind of BIOS you have, you may need a different cable/clip or drop in adapter than what's in the kit I linked above.
Does your manual show BIOS chip example on the block diagram? If yes, how many pins?
Show me an image of the board if you can, when time permits, I will see if I can locate the BIOS chip for you.

Did you reach out to Supermicro? If not, do that, via email or chat, they may have some process to update BIOS without CPU/Memory, best to ask in case they do

Just to update you @Lost_N_BIOS My server arrived today (supermicro SYS-6029P-WTRT with mainboard X11DDW-NT). Getting my ducks in a row before I dig into it. It was built to order, so it's quite likely going to have the latest BIOS 3.4 loaded. I 'm not sure if that will prevent me from flashing the custom BIOS you edited for @cmoski . The official updated software package for the board is here. https://www.supermicro.com/Bios/softfiles/12570/X11DDW_3_4_AS17305_SUM250.zip

When I reached out to Supermicro previously they were rather prickly about me using ES chips and shut me down pretty quickly with regard to flashing procedures. However, the manual provides a procedure for flashing from USB. (https://www.supermicro.com/manuals/motherboard/C620/MNL-1907.pdf page 76)
I'm hoping the presence of the CPUs and LRDIMMs will give me access to the BIOS utilities, regardless if the pre-production stepping is recognized for boot purposes. I'll be back after I clean my basement a bit more. lol

Well, after several attempts I so far cannot access the BIOS with the QL28 CPUs installed. The white Supermicro boot screen hangs at CPU initialization. IPMI/BMC appears as an option when I connect LAN cable to the IPMI jack, but the BMC username and password do not work (they are printed on barcode stickers on the front of the server and on the MBD; I also tried the old ADMIN/ADMIN values, but as I figured, those didn't work either). I imagine that without the proper BIOS settings, the BMC username/password is useless.

@cmoski doesn't respond to tell me how they achieved the BIOS update that allowed the use of the QL28s.

I've investigated flashing the winbond chip directly with a programmer. However, I haven't found any certain confirmation that this specific chip can be programmed with the tools posted in this forum. And the winbond chip is also soldered to the board, and I have no confidence in my soldering skills.

I've resorted to purchasing an inexpensive used Xeon Bronze CPU ($109 + S/H). I should be able to boot into BIOS with that CPU and hopefully upgrade with the modded BIOS provided by @LOST_N_BIOS. Xeon Bronze should be here in the next 5-7 days.

I received my Xeon Bronze and was able to boot the machine.

Using this AMI microcodes Guide I attempted to add back in the old microcodes, but was completely flummoxed by Step 3. (so out of my depth here)

@Lost_N_BIOS would you be willing to reintroduce the same microcodes into BIOS X11DDW0.B07 that you added into the version you uploaded in message #9 above?
Your work above has the old microcodes for Engineering Samples

Since I'm now up and running with v3.3 should I just repost the v3.4 mod request over in REQUESTS?
