Slow write does not matter, wait it out

For MX25L12873F all these work >> CH341A v1.31(1.4) (CH341AFree) (This is the name of the folder), ASProgrammer 1.4 or 1.41, or CH341A v1.1.1.32
16MB Rom size does not matter for any of this????? If you mention that due to CH341AFree version, pick correct type first (25) then pick correct size (16MB)
Write speed should not be a concern here, only proper write once done is all that matters

OK, fine, It worked! AsProgrammer was good, I write with AsProgrammer 2.1 and verify with 1.4.

Does it have any other data in other empty items?

No, that BIOS had both areas put in it So all success then, and system boots properly? If yes, great!

Yes, this system boots properly ! You are so GREAT!

I mean there has some items shown “Default Strings”, Does we have anyway to fill these items ?

Great to hear it, you're welcome!! That is all normal for MSI
We can enter info there if you want, but it's not there by default generally. Last image, that is for case type models, so nothing would ever be there for you anyway
But, if you want, we can put serial in first image serial location - Do you want me to make that edit to GbESMBFlash.bin and send to you? See, serial is already there though, first image, towards bottom

I think I can put these items with AMIBCP, in DMI Tables, right? But I don't konw what each "Type" corresponds to = =

@June Da Pek - Yes, you can do with AMIBCP sort-of, but that will break the FIT Table and BIOS may brick or microcodes wont load properly.
So, you have to do the mod with AMIBCP, then with UEFITool 25.0 pull BODY of AB56DC60-0057-11DA-A8DB-000102EEE626 out (Expand twice to RAW, then extract BODY of RAW), and replace in other known OK BIOS, so FIT Table does not get broken

For first image above "System Information" to put serial in DMI at AMIBCP, go to System Info, and in #4 slot under #3 - 2.0 put Serial, then save, then pull out BODY of module mentioned above and swap back into known OK BIOS
But again, this information is NOT there by default, always only "Default string" or generic Data like 0123456789 for stuff like this, or blank (FF/00/30 etc)

I search and find the GUID AB56DC60-0057-11DA-A8DB-000102EEE626, but this file can not expand and it is not raw file ,it can just save as bin file when I right click and choose Extract body.

Ohhh no,My AMIBCP 5.0.2.0023 can't save this change, the program will stop

@June Da Pek - Sorry for any confusion, AB56DC60-0057-11DA-A8DB-000102EEE626 is a sub-GUID of DAF4BF89-CE71-4917-B522-C89D32FBC59F
I simply meant to expand DAF4BF89-CE71-4917-B522-C89D32FBC59F fully down to AB56DC60-0057-11DA-A8DB-000102EEE626 (And sorry, I thought that said RAW without looking back)
So after AMIBCP edit you extract and replace body of AB56DC60-0057-11DA-A8DB-000102EEE626 into NON-AMIBCP edited BIOS, as you see in this image below


Use AMIBCP 5.02.0031
