@l1d1ya :
I have merged your 2 posts (to save space), moved your request into this already existent 100% matching thread and hope, that this is ok for you.
@MiesMosel is the best person Iāve seen with modifying AMD Microcodes, hopefully he can help when he has some time. Often, microcode is stored in āHoleā modules in some AMD, which are only shown in certain CBROM versions, but I have not looked at the BIOS you mentioned, will check if Miesmosel doesnāt
I checked with all cbrom and cannot find any āHoleā regions in this BIOS, hopefully Miesmosel can help you
Hello!
Holes - I only know from AMI BIOS, but this is Award/Phoenix Non-UEFI BIOS.
This BIOS doubles the MCs & maybe binds it near together with AGESA - I donāt know exactly!
I could exchange the MCs with the new by using HxD, but I couldnāt fix the checksum.
CBROM finds all OROMs & shows minimal the MCs. I used the original BIOS F8f from Gigabyte.
Iāll try some more times ā¦
ā¦ or if somebody wanna check+fix the checksum (should be āXX 00ā, where XX could be every hex from 0-F, but 00 has to be @ the end) ā¦
Regards, MiMo
!!! I canāt give any guarantee/warranty, but i made this by best purposes & knowing. Use/Flash of own risk only !!!
Be aware, the checksum isnāt fixed yet!

GIGABYTE SPI Flash BIOS Update Utility v2.13

And how is the checksum, which digits?
Thanks for stopping in and helping @MiesMosel - Iāve only seen Holes in cbromxx AMD BIOS, so I donāt think those were AMI, but Iāve only seen it a few times since I donāt mod AMD often. Your cbrom image shows total āHole area spaceā too, but the holes themselves are not shown like Iāve seen before.
Hereās a recent thread I remember with Cbrom/AMD and holes 
Gigabyte GA-M68MT-S2 REV1.3 CPU BIOS MODS? (2)
Checksum which would be shown on your mod BIOS in Qflash if not error, or maybe still shows(?), is 8e4b (Hex 4b8e - 40x instances in BIOS) (64x instances in BIOS for original 8e4b)
I do not know how to read a checksum and where to edit checksum.
I think that at address 0x210000h is the AMD module. I looked at the sources of the project "coreboot".

What will he say? Can this be a module "AMD"?
I have no time at the moment, but I look at it at weekend.
Editing AGESA is too complicated for me at the moment. I donāt know anything about it.
I only know, that itās not only one module. Itās related & implementated to/in some other modules.
What I could try is, to find out a CBROM version to fix in any way the checksum.
update with a thing, the bios evga no work, i have download xfx bios and work fine but i have quit clr cmos jumper because no bot with that in mode disable
790i_P10_XFX.rar (510 KB)
Hello pipes80,
am I understand that right, that ā¦
1. the Asus A8N5X BIOS v1003 (from me) is working for you?
2. the Evga 790i SLI vP10 could be flashed, but is not booting?
Any checksum problem shown by Flash tool? Is there any error message on Post?
3. What is the problem with the XFX-BIOS? I donāt understand what you mean. Could you please explain with other words?
- āquit clear CMOS jumperā make no sense for me,
- What do you mean with āno boot with that in mode disableā?
active āclr cmosā? Clr cmos should only used some seconds & then put jumper back to default.
something different?
Regards, MiMo
practically initially the nforce 790i ultra worked with the bios xfx and without jumper in normal mode, only with that or without that jumper does not change anything, it goes and not goes, when you can turn on and access the bios is all very slow
I donāt understand what you mean.
in a nutshell now the card succeeds and fails to make the post of the bios and when it does, the navigation in the bios is very very slowā¦
I noticed that using the award bios editor, surfing the system bios is very slow while trying with the asus bios does not happen
Solved, thx for support
Hello pipes80,
both BIOS are working now?
Hello, do you know why this bios havent NCPUCODE.BIN ? Mobo is a p35c ds3r. Trying to figure how to add the xeon 45nm microcodes. Thanks

Nothing happens.
@robers - Gigabyte P35 is tricky, you cannot see/edit/insert NCPUCode.bin, only the insert /cpucode CPUCODE.BIN method works, or direct hex edit on the BIOS itself - latest BIOS version is F12 or F13d (last beta, contains most fixes and improvements)
Here is F12 and F13d with latest versions 1067A+10676 covering all platforms
http://s000.tinyupload.com/index.php?filā¦792171636999364
@nippy - link exact BIOS exe, I will check. If nothing happens in cbrom then usually not compatible with cbrom at all, or not compatible with that cbrom version
