What I mean with " reboot twice " is that. After setting the jumpers and booting up to windows, I tried to dump the Bios, but FPT was still unable to dump giving the same error message as before changing the jumpers.

Only after another restart of the PC, I could dump without errors.

Apparently the systems needs to start up fully twice with the jumpers moved to allow the dumping. After that however, the dumping is possible as long as the jumpers remain at the disabled position.

I'm a bit late for this thread anyways I'm grateful for Spam00r & Lost_N_BIOS for having this discussion on M92P bios fix. And it saved my IS7XM mobo.

@Spam00r
Is it you mean that dumping full bios needs " reboot twice " ?
What I want to know more is :
Could you ever tried to flash the bios which was modded into this mobo after rebooting twice?

I flashed the Bios that Lost_N_BIOS posted above without any issues. How far reaching his modifications were, he may explain in more detail.

@gloobox - put on jumper, boot to windows, shut down, boot to windows again (= reboot/boot twice) then FPT dump or boot to DOS and FPT dump or flash etc. I assume, booting 3-5-10 times is fine too, just not once

@Lost_N_BIOS
I had done as you said,and tried 10 times rebooting but failed all the time.I still couldn't flash the modded bios with FPT on IS7XM.

@Lost_N_BIOS
Awesome!I found something new in this bios.When I open the AMIBCP,turn to page of the BIOS Strings,you will find many term which don't show in the page of SETUP Configuration.
Such as the term of "Me FW Image Re-Flash"


On the other hand,I found "Me FW Image Re-Flash"in the uefitool,and it located the text is in the GUID: 97E409E6-4CC1-11D9-81F6-000000000000 of Setup module.But I still couldn't find the "Me FW Image Re-Flash" in the txt file after extracting by the IRFExtractor.


Could you help to show it?I think it could help to flash the modded bios.
I have uploaded the full bios dumped file.

@gloobox - Yes, this often left in BIOS strings, also sometimes you see internal AMI stuff, under language name (AMI something)
This option is removed from BIOS, only left in strings (This is text string only 97E409E6-4CC1-11D9-81F6-000000000000), thus there is no BIOS option for that so you don't see in IFR
This is very common with removed BIOS options, but strings left in, due to lazy engineer building on base BIOS and removing options but leaving string

Are you giving me random BIOS unrelated to thread board again?

What error are you getting when trying to FPT Flash? If 28, try PRR/PRR2 tool

@Lost_N_BIOS
Thank you for your explanation!
This topic we talk about the M92p Q77 Tower BIOS,and the bios I memtion is M92p too.I'm trying to solve this problem in flashing the modded bios of this machine.
It would only show error 280 in these mobo even I shorted the ME_DIS jumper.I will try pin-work to see if something would change when I got these mobo next time.
