I would like to request you again for another BIOS mod. This time, it’s for only disabling Intel ME for a MSI Godlike Z390 board. Mostly setting up the HAP bit.
Here is the BIOS .bin file from the board dumped using SPI flasher.
the offset for shutdown exists in the bios, … but you have a broken ME FW - 0.0.0.0? CMOS RESET ,.,or ME FW tools “from EFI or DOS”.,.or try last bios
flash with HWflasher can also break the system “impossible flashing MSI official files !!!”
edit
best to start with ME system tool “MEManuf .,.in EFI” find more info.
it is possible that your problem is not related to ME FW at all “or have HWdefect on this chip”
,.,. ME system tool 300series for debug info ,.,.no flash !
try your bios backup !!!
…,bios is possitible get on backup ?? ,.here is visible ME -12…x…x.x or 0.0.0.0 ?
if still get boot-loop
verify storage’s is visible and you using UEFI + GPT or any special NVME ? /CMOS RESET / verify SATA controller vs device .,.etc
EDIT
or when you have the option to flash the original files for repair
try this + variable offset “in GRUB / RU.EFI”
but disable ME - broken ME FW “it usually freezes in this position !!!
.,recommend find ME FW change-log here is this problem visible for older version - MSI using only old FW”
try disable ME - only on newer versions “for functional control on/off state”
MEcleaner -this is more aggressive way
.,.easy way for corruption in ME FW not must works re-flash for repair
//////////
,.,but i not recommended disabled ME !
it is better to try the update or ignore all about “ME FW” when all works
.,.if your ME FW stuck - 0.0.0.0
“must try contact @svet on msi forum” but most time is this error forever !!!
also device SN and some next ID missing in bios “for msi sw” this not must works / also device not must works normal “this is how it was with MSI laptops”
