* But FPT12.x Win10/64bit works! both dump and write work like a charm!Īnd now I have already made a customized BIOS via AMIBCP5.x, then have it flashed back successfully! it get stuck after the banner text of FPT “Intel® Flash…All rights reserved.” same as DOS. * FPT12.x EFI version doesn’t work either. it get stuck after the banner text of FPT “Intel® Flash…All rights reserved.” and then nothing happens, no error, no exit, just hang. and there is no such entry like “ME Tools” during POST process. they didn’t mention the ME stuffs in there docs and specs, nowhere.

Seems like they are trying to hide the ME things probably coz the server motherboard has full featured BMC and IPMI inside, they are much powerful and easy to use. * None of MEInfo including DOS/EFI/Win/DOS doesn’t work at all, just get stuck silently. * Unable to get the ME version from hwinfo64 either, it shows nothing in ME firmware version field. * They hide all ME firmware related information in the BIOS, no version at all. Hi thanks all of you here I bring good news! ±-±-+Įrror: Detected CSE Extension 0x16 with wrong Partition Hash at OPR > FTPR.man! The bad news is that it’s SPS 05.00.03.101.0 (PC), the possibly good news is that in the folder SPI_UPD are both spsFPT.efi and AfuEfi圆4.efi (according to readme 5.) which both should be able to flash a complete image? You can look into the original bios file from gigabyte, there’s a folder SPI_UPD and Relnotes. I’m now heading home and will start working on it soon.

If that doesn’t work, I’ll try to figure out how they calculate the last two bytes checksum and go with the BMC offline flash. Many thanks to this forum I can easily find what I need.Ģ.

I’m pretty sure the version of ME is 12.x coz the chipset is C246, a brandnew C240 series chipset, which only supported by the latest ME tools. Go with FPT.efi first, dump the bios and flash back. and ROM is fixed.īut after taking a look at the BMC flash payload for other two similar MB, I realized that the last two bytes 0x31 0x59 is dynamic, probably a checksum or signature, which I need to figure out too.ġ. (Sorry I tried many times but still unable to render the attachment as image, just click at the blank space to open it) rbu extension), comparing with the standard image payload, seem like they just append a few extra bytes at the end of the image, as below: I have checked the BMC flash payload(a file with. Since the BMC on this MB is able to program the bios when MB/BIOS POWERED OFF, it probably works like a physical programer! May I know how does the “18 - error secure flash rom verify fail” check work? it’s more like a signature check by running BIOS? or it’s just a special bit flag in the ROM? or it’s just a check in flash tool? Just in case someone want to check the BIOS feature and screenshot of this motherboard: Here I’d like to provide the original gigabyte rom and my backup.

but if I flash the ROM with the gigabyte original ROM file, which downloaded from gigabyte drivers page, everything work like a charm, so I’m pretty sure I’m in the right path. I couldn’t find any secure-flash related options in BIOS/UEFI settings so I’m unable to disable such feature. I tried to use Gigabyte provided 5.09 and AMI latest version 5.12 of AFU, both of them failed with error: 18 - error secure flash rom verify fail Yes, afuwin freezes the windows 8/10/PE, afudos freezes the FreeDOS and MSDOS, afulnx freezes ubuntu14/16/18, that’s crazy.Ģ. I tried to use afuwin3.05, afudos3, afulnx3(with /GAN), all of them led to a whole system freeze.

Try to restore the backup copy with same afu toolsġ. Backup the BIOS/UEFI using afu backup.rom /O, under Windows, Linux or UEFI APPĢ. Gigabyte Server motherboard MX32-4L0, see īypass the “18 - error secure flash rom verify fail” error when flashing back the modded BIOS or original-backup ROMġ. It took me a whole week trying to figure out what happened on my gigabyte server MB, hopefully someone here could help
