[Guide] How to extract/insert/replace EFI BIOS modules by using the UEFITool

Intel RAID orom is in the "RAW" section of CMSCore - A062CF1F-8473-4AA3-8793-600BC4FFE9A8 when looking at the file using UEFITool

With extracted body, the orom starts at 00010018 with 55 aa - and ends at 0002dc17 with a block of 320bytes of FF >> Total of 121,856 bytes / 119KB

That can be updated via hex extract and update then reinsert, or by putting updated bin file name SataOrom.bin into the Files\intel\RST folder.
Test example using UBU shown below

UBU_OROM-RST.png



SATA90? Have no clue what that is, but it’s likely not needed or used here, never heard of it myself, nor have I ever heard of anyone updating/discussing that?
You made me look, I searched entire site and your post is the single result here for SATA90

This stuff you mention >>>
# SataOrom.bin DevID 2822/282a
# RaidDriver.efi

Example of how to put file in there is all I think, however, the random orom I grabbed for the sample image above is 2822/282a, I assume yours probably is as well.
Check in hex, at the top, under version info, right after PCIR and before “Intel Corporation” you will see 2a 28 22 28
I checked 12.9 version (Intel-RSTe_RAID-ROM_v12.9.0.2006_TRIM-mod-acc-CPL0) and it’s same as mentioned above too, these work in UBU for your boards BIOS as mentioned/shown above

I’m unable to flash NvmExpressDxe_4 as when I load this in UEFITool I gets error “UEFI volume not found”

@uzairali001 - You have to open BIOS in UEFITool, not NvmExpressDxe_4, then find location within the BIOS per the guide to insert NvmExpressDxe_4 using right click functions
Please read the steps of the guide again, then do them slow one by one.

Finally found a forum that may help me out.

I have a new HP Pavilion Gaming Desktop - HP Motherboard 843B using AMI V2.20.1271 / BIOS REVISION: 84B VF.20. I am aware OEM manufactures take the BIOS/UEFI and strip it down.

Anyways, I’ve been searching for a BIOS utility and stumbled on this UEFIT tool. What I wanted to do is replace the boot logo (in my case the HP logo shows on startup).

I even called HP support and they don’t have any utility. Ditto for AMI.

Question:

1. Does this tool have the function to change the splash logo? And compatible with my AMI version provided above.
2. Looking for instructions if available.

Thanks,

Jay.

@SpaceCrime - yes, possibly, but flashing modified BIOS may not be easy for you (and it may not be possible due to security/RSA, Sure Start since you mentioned HP)
Do you have flash programmer? If not, order CH341A flash programmer and SOIC8 test clip cable, these are on ebay for around $2.50 each and I suggest you have both in hand before you attempt to do anything.
Give me the exact system model name, or a page you download BIOS from and I will check it for you. The info you have above is no use without model name.

Thanks…

Here is my HP weblink for downloads:

@SpaceCrime - Thanks. Yes, logo can be changed, but without programmer it’s risky, and still may fail to work even if BIOS edit is OK, due to RSA/Signature Security
Without knowing for sure what would work you should keep image to 259x259 max & jpg, since that is largest used (6x1 logo and 2x other is in there 108x108 - 259-259px)

Download Intel ME System Tools V12 here in section C
Intel Management Engine: Drivers, Firmware & System Tools

Inside you will find Flash Programming Tools folder, and inside that a Windows or Win32 folder. Select that Win32 folder, hold shift and press right click, choose open command prompt here. Then run command below
FPTw.exe -bios -d biosreg.bin

Send me that file, and your image, I can make test BIOS for you if you want to try, but I highly suggest you wait until you have programmer and SOIC8 test clip cable in hand.

You will need to first boot to grub and use setup_var to disable BIOS lock (variable you need to use is 0xB45), so you’ll type the following at grub prompt
Serup_var 0xB45 0x0

Here is general guide on how to boot to unlock this, mainly you’ll need to check the steps 6 onward, I gave you variable above from steps 1-5.
[GUIDE] Grub Fix Intel FPT Error 368 - BIOS Lock Asus/Other Mod BIOS Flash
And you probably need to use the method I showed images and explained here to get to a bootable proper shell/grub
Alt boot to grub when no boot to EFI on exit page - [Help needed] Hidden Advanced menu Bios HP Z1 J52_0274.BIN (2)

^^ BIOS Lock must be disabled before you can attempt to write back any BIOS region using FPT ^^
The above must be done if you want to try before a programmer arrives, otherwise with programmer none of that will be needed

@Lost_N_BIOS - Many thanks and appreciate your effort into finding out for me on this. I didn’t expect it to be that complicated. At least I know it can be done. I will re-think if I really want to go through…just worried I may brick my PC.
I’ve done this logo change on my previous ASUS PC which wasn’t that bad. I’ll see. Thanks again.

@SpaceCrime - You’re welcome. Yes, Asus BIOS this much easier, less worry than locked OEM type BIOS. Order CH341A flash programmer and SOIC8 test clip cable, then you wont have any worries about any BIOS ever again.

Tell me why modules need to be inserted after the lowest module, and not in the center for example?
If I extract modules from a specific location, can I or should I insert them into the same location in my bios?
for example:

3.jpg

Because the required space for the insertion is only available at the end of the related Volume (beyond the undermost listed module).
If you want to insert a specific DXE Driver module into a specific location of the DXE Volume, you have to remove as first step all modules of the DXE Volume, which are listed below the desired location, to insert the desired module and as final step to re-insert all previously removed modules - one after the other - beyond the undermost listed module of the related Volume.

@Fernando Doesn’t UEFITool know how to automatically move / move modules after insertion?

UPD: As I understand it, after comparison, UEFITool copes with the insertion of modules not only from the end!
IMG Gogole Drive

UPD2: After removing modules from the original bios, everything looks the same.

No. The UEFITool does, what you want (no matter, whether the modded BIOS or the related module will work thereafter).
The AMI MMTools v4.5 and v5.0.0.7 are safer and more comfortable regarding this point. After having entered the correct number(s) of the “Volume”, where the DXE Drivers incl. the module named CSMCORE are located, and browsed to the *.ffs module you want to insert, you can click onto the “Insert” button and the desired module will automaticly be inserted into the correct location (= undermost of the DXE Volume).

@Fernando Many thanks for the clarification and for the wonderful forum!

Hi…

Somebody can help me to mod foxconn p67a-s bios or support ivybridge?
I’m using UBU and succes save bios,but when i flash to the board became brick when i put ivybridge processor.

@hasandoel2 - does the mod BIOS you made work with Sandy Bridge? What is your ME FW, check BIOS main page or download HWINFO64 and on the large window on left side, expand motherboard and find ME area, inside that get the ME Firmware version.
Sometimes nothing you can do if ME FW is v7 And you/we cannot update v7 to V8, this has to be done by manufacturer due to many other BIOS modules also need updated during that switch over for Ivy.

@Lost_N_BIOS - i’ll check later soon as i go home.
thank you sir

@hasandoel2 - See my reply here - Intel, AMD & VIA CPU Microcode Repositories Discussion (16)

@Fernando
Finally I have some more time to spare for following your guide: “[Guide] How to extract/insert/replace EFI BIOS modules by using the UEFITool
With the help of a direct connection between the BIOS Chip of my MSI A55M-P33 motherboard and the CH341A programmer I could now dump the BIOS file. Now I could follow your guide until B (insertion of a native EFI module). At point 3 “Expand the DXE Volume and scroll down to the undermost module, which is listed as “DXE driver” I cannot find the undermost module! A screenshot attached!

Can I ask you here for a little help?

Thanks and best regards,
Cyanno
