Upon opening the 20655 modded file in MCExtracter, the 20655 shows up fine(all other Microcodes are removed including the pre-production ones. Using Micro Code option, I inserted the 20652 MCU and the 20655 MCU separately into the file and obtained 2 modified files. Next, I attempted to use EzH2O V2.1.0.13 to modify this. bin format from, I ran them in MCExtracter and they came up as 0x2400(20652) and 0x1000(20655). The new Microcodes for these CPUIDs, in comparison, are larger. I noted that the size of the 20652 Microcode is 0x1C00 and the size of the 20655 Microcode is 0x800. Upon placing this file in MCExtracter R64, both 2065 comes up as outdated which is expected. I did this twice and verified the checksums, and got INSYDE-1.40.ROM as output. The 460M however, is strictly 20655.įirstly, I used Universal BIOS BackUp toolkit 2.0 to retrieve my BIOS. However, I might consider upgrading it to an i5 460M in the near future because they are sold for just a few bucks second-hand. Using AiDA64, I have verified that my i3 is of CPUID 20652. Hence, I wish to modify the BIOS to add new microcodes for the following CPUID :20652, 20655 so that it is protected against Spectre V2.įrom what I have gathered, CPUID 20652 is for i3 3X0M only, and 20655 is for i3 3X0M and i5 4X0M.
