I find three instances of Test al, al in assembly that lead to infinite loops, so not sure which applies to your hardware issue, you'd have to test bypassing each one at a time.

Hi Lost_N_BIOS and chaus - this entire thread is very informative. I am working on this same project myself on an M73 and am having a hard time progressing. How did you find this GUID? I am unable to find any of the error text as you did. My ROM dump (obtained from board with CH341A + SOIC8 SOP8 Clip) is attached

Thank you!! I will be trying this on my machine as soon as I get home tonight. Will update here!

Happy to report that upon erasing the BIOS chip and flashing this I am successfully bypassing the whitelist! Thank you very much for sharing, you have given this hardware new life for me!

Someone else messaged me asking for details on how I made this work. I am NOT an embedded hardware dude and mostly pieced this together from other helpful people on this forum, but here's the step-by-step that I used, more or less:

  1. Dump the ROM file using the CH341A clip and the AsProgrammer software (found here: https://github.com/nofeletru/UsbAsp-flash/releases/). Mine was finicky and took some adjustment to make good, reliable contact. If you get all zeros or errors, try messing with the clip positioning.
  2. Download and run UEFITool (I shared out the version I downloaded because god only knows where I found it originally: https://bruker-my.sharepoint.com/:f:/p/j...g?e=M1ZcMX).
  3. Open the ROM file in UEFITool.exe (NOT UEFITool-old.exe, we'll use that later).
  4. Go to Action ==> Search ==> GUID, and search for this GUID: CEC0D748-7232-413B-BDC6-2ED84F5338BC.
  5. It should pull up only one search result. Double-click that result to go to that location in the ROM file.
  6. Expand the GUID in the treeview, then expand "Compressed section."
  7. Right-click on "PE32 image section" and select "Extract body ..."
  8. Download and run HxD hex editor: https://mh-nexus.de/en/downloads.php?product=HxD20
  9. Open up the file you saved when you extracted the "PE32 image section" in HxD (by default it'll be called something like "Section_PE32_image_CDC0D748-7232-413B-BDC6-2ED84F5338BC_ErrorMessage_body.efi").
  10. Scroll down to 000041C0, and highlight the value in the '04' column. It should have a value of 74. You want to change this value to EB. This is the magic! It's machine code for "skip this section that does a boot loop if weird hardware is found."
  11. Do a File ==> Save.
  12. Now open up the ROM file you dumped in UEFITool-old.exe.
  13. Drill down to Intel Image ==> BIOS region ==> 8C8CE578-8A3D-4F1C-9935-896185C32DD3 ==> CEC0D748-7232-413B-BDC6-2ED84F5338BC ==> Compressed section.
  14. Right-click on "PE32 image section" and select "Replace body...", then select the modified .efi file you created in Step 11.
  15. Do a File ==> Save image file... and save this as something like "M73Modified.rom" to keep it separate from the original dump.
  16. Close both UEFITools, and open up AsProgrammer again, then wipe the ROM chip and reflash it with the new .rom file you created. Just flashing over it without wiping it is known to cause issues.
If everything worked, you should now have a whitelist-free M73 TFF!

I don't have any other of that model to test with, so I have no idea if the GUIDs will be the same, but based on other posters' results, I believe they will be.

Anyway, let me know if this works for you! Few things give me as much satisfaction as helping someone else stick it to The Man. ;-)

Wish i can get this support from members :c
The thing is i have AMD asrock ab350 fatality k4 gaming, but i'm so noob, i'm asking for help cause i want to unlock all features on this mobo, to fix the cpu issues with high latencies and audio stuttering and API insufficient resources, and here in Venezuela situation is so difficult to do RMA, cause is so expensive to sent back to Asrock, also they don't care about rma :/

This is the rom i'm using: http://asrock.pc.cdn.bitgravity.com/BIOS...83)ROM.zip
And the AMI BCP version is: 5.02.0023 and i don't quite know if this the proper software version for my Motherboard model and current bios

Aff :/

I have a Lenovo M93 with this board.
I purchased a i5-4590T Haswell refresh cpu, hoping that will work since it is in the supported cpu list here: https://download.lenovo.com/parts/ThinkC...062014.pdf

The pc starts, but doesn't boot, so I guess the microcode is not included. If I put back the old G3220T, then it boots nicely.
I am using the latest bios from here: https://support.lenovo.com/gb/en/downloads/ds035753

The question would be, how to update the microcode to support all the haswell 35w, 45w and 47w cpu-s?

Hello @chaus and @lost_n_bios,

I have similar machine, Thinkcentre M93p Tiny using i5-4590T, but next on the side of the yellow chip (MX25L6473E) on the empty spot on your motherboard, my machine got another chip which is MX25L3273E. 

I am also would like to have the whitelist removed, first by trying to search the whitelisted card (in my case, tried to search Intel 7260 card that is in the whitelist, 8086:08b1 in reversed order) but I cannot find it).

Please have a look on my file and help with the whitelist removal.

Thank you.
