I don`t have a hardware SPI-programmer as yet thought I can still flash my modded BIOS using the BIOS USB flashback feature because I have tested this out myself on my board when modding the BIOS with a newer Intel RAID ROM module.
Thanks in advance for the help and feedback.

Thanks mate for having a look into it for me. I have read that it is best to update to latest Intel CPU Microcode for your platform if you can. The advantages of using a up to date Intel CPU Microcode is it can give a more stable running system and better overclocking. I take it this is true about the advantages of using a up to date Intel CPU Microcode?
EDIT 1: The Intel CPU Microcode the above official BIOS contains is Microcode : MU063F0229 and is what my board is using for my system. I fount out what my Intel CPU Microcode version is by using SiSoftware Sandra. That is the Intel CPU Microcode version SiSoftware Sandra is showing for me for my system.
Ok. Take the first test. While changes in - OROM IRST 13.5.0.2164 (2 modules) - OROM Intel LAN PXE GE 1.5.61 - EFI IRST 13.5.2164 - EFI Intel LAN UNDI GE 6.4.13
If fashion sew and everything is working fine, the next test will change the CPU microcode. Waiting for results.
Well the BIOS flashed without issues I think but something is not right as the system is experiencing crashing issues with the modded BIOS which possibly means something not like what has been changed or something not right with the mod.
The Lagacy OROM IRST 13.5.0.2164 and the OROM Intel LAN PXE GE 1.5.61 seems to be working fine thought I am not sure how to test the others.
Is that a fresh mod you have done with just the CPU microcode upgrade? That would be best because it would rule out issue that may be caused with the OROM modules being changed.
@SoniX I think that will do for the moment. I will test the stability of the new microcode and post here whether I notice a difference or not and if I experience any issues I have not had before since the microcode was updated. Thanks again SoniX for your time and help with this mod.
@sinders Stop! Check the third test. Since FFS file microcode has 2 status! BOOT-YES and BOOT-NO. Who was stitched with the status BOOT-NO. In the original BIOS status BOOT-YES. This can be seen by entering a command in the command line "mmtool <BIOS file> /p". MMTool 5.00.0007.
So, what has been done. Taken BIOS files from Gigabyte and Asrock. With MMTool5 been updated microcode CPU and extracted FFS-file "as is". With UEFITool v0.20.1, was replaced two files in the BOOT-volumes.
2 finished attaching the file to X99 with different statuses BOOT. I do not know how important this status. But I think that it is better to stick to the original. 2 status in FFS flle with microcodes.
I have tested your third mod and the system seems to boot just fine. I take it I should keep to using your third mod for the longer testing of the updated CPU microcode since you said it is better to stick to the same as the original which is BOOT-YES?
