Used to replace CON ME. Need to cooperate with ME cleaning tool. Can solve 100, 200 series motherboard using 8, 9 generations of CPU memory can not overrun and can not identify the problem! It also supports 1151 Xeon CPU series.
Use me_cleaner to cut COR SKU ME FW, whitelist MFS, and it will become 2.5MB.It can be put into ASUS/MSI’s flash chip, but other need change flash chip from 64Mb/128Mb to 128Mb/256Mb for larger ME Region. Now remove FF at the end of FTPR partition. Move MFS forward to make ME FW less than 2MB so that it can fit every motherboard’s Flash Chip. That’s what @shixinyuan have done.
The reason for this is we found COR SKU ME with Reserved bit can run Xeon on non-C PCH.
Hi, I’ve been using this mod for my Xeon E-2246G on Z370 for quite sometime with no issue at all until I change to Asrock B365 Pro4 recently. I was able to mod/flash/boot up as usual but one of the pcie x16 slot is not working (first boot using xeon on this new board) I ignored the problem since I only use one slot anyway until later on the second pcie x16 slot stop working out of sudden. I have tried reinstall windows/reflash bios/check hardware connection/reinstall drivers, basically repeated every steps at least twice, tear down the whole parts and reassemble, reflash, reinstall etc but nothing seems to fix the issue. I have tried using different Me version but only the 18.104.22.16864 Cor HDA version able to boot up. Hwinfo shows no WHEA error but the DMIDecode area shows incorrect PCIE slot info, where the Slot Data Bus Width: 16x / x16 shown as Slot Length: Short and Slot 1x / x1 shown as Long. Not sure if this is indication of any issue with bios or driver/system, any opinion is very much appreciated. I have attached my bios dump here just in case it’s needed.
@pow - Link me to your BIOS, so I can see what you are looking at on the current BIOS. The name of the ME FW in the first post has nothing to do with what you should choose for your system Maybe I’m confused on what you wanted/asked? If you want the file from first post, it’s there attached.
Latest corporate one in the repo is 22.214.171.12464_COR_H_DA_PRD_RGN, this should be in the package you downloaded. Corporate ME FW will not be 1.5-2MB, it’s generally or always 5-7MB+ From what he mentions, it sounds like you also need to disable ME FW via HAP bit in FITc (ME Kernel >> at bottom >> Reserved >> Set Yes) while you do the settings transfer, before you flash it into your board.
And @shixinyuan - can you please confirm, is that the only version you know to work, and others fail, or is that the only version you tested and disabled ME FW so you know it works?
@evonnewoon - sounds like faulty motherboard, bad slots, or damaged CPU or CPU socket pins, or damaged PCH maybe. Or, it may be you are not transferring settings properly from your original ME FW into the new ME FW before you flash it in there (This is 100% a MUST DO THING)
@Lost_N_BIOS Thanks for the reminder on transferring the ME FW settings, I might have forgotten to repeat this step when I was rebuilding the whole thing, will try it now and update on the outcome once its done.
@evonnewoon - You’re welcome! Hopefully that is the issue with your PCIE slots! You always have to do that, can’t just stick in stock RGN or it will mess up lots of stuff usually, unless you flash in with ME FW Update tool.
@Lost_N_BIOS Thanks a lot. You nailed all information i was searching for. Albeit I was able to puzzle some information together by searching the thread you mentioned and taking a look on station-drivers. But i have one last question: What does DA D0 mean? Or what are the differences between them and can i substitute one with another if cleaned?
Does the following quotation mean PCH Stepping D0 is the same as DA?
@Lost_N_BIOS Unfortunately it didn’t work, still the same as described previously. I have tried using ME FW Update tool as well, but nothing seems to be working for now. Besides the both Pcie x16 slots, the first M.2 slot is not working at all. The second M.2 slot however can only support SATA mode which my SSD is plugged into but not the Optane. Hwinfo shows that all my Pcie slots and M.2 slots are empty when I’m actually using one of the M.2 slot with my Sata Ssd. Hoping someone could shed a light within this issue.
Unfortunately this version MEFW.rar (518.4 KB) doesn’t work on Asus prime B250m-c (original bios 2001- ME 126.96.36.19990 con H) but it works with the ME version from the first post 188.8.131.5261_COR_H_D0_PRD_RGN.zip (304 KB).
when I compare these two regions, there are more partitions in yours, if they are partitions:
IVBP not exist in > 184.108.40.20661_COR_H_D0_PRD_RGN.zip (304 KB)
FLOG not exist
UTOK not exist
ISHC not exist
according to my test, the more partitions wont affect. and i can remove them too. here comes me fw with ftpr and mfs only. 220.127.116.1123_COR_H_DA_PRD_RGN.rar (316.2 KB)
and the modified bios with me fw in #18 PRIME-B250M-C-ASUS-2001.rar (4.6 MB)
the bios support all lga1151 or bga1440 cpu from skylake to coffee lake, not including skylake es(stepping below 3) or comet lake (stepping not 0xd)
