I have a hex editor (wxHexEditor v.24) but I’m new at this and would like to be able to follow your guidance to add “0x00 padding of 0x400 size at the microcode end” but I am not sure exactly what that means.
Should I just add “00” to the end of that 106a5.bin file using the editor? 0x400 = 1024 so do I just tell the hexeditor to inject 00 for 1024 bytes? I have attached a screen cap of that option:
UPDATE: That is exactly what you meant… I got it to work by adding those 00 in each byte up to exactly 12k (12288)
Here is the padded bin for CPUID 06A5 update rev 1c that will work with MMTOOL. I have an Asus P6x58d Premium mobo.
