Double-clicking on the line in the “Messages” window highlights a line in the “structure” window. The result of the search with the address should appear below (Messages). (Section GUID), select “Header only” and confirm. Using the “Search …” function (File menu) in the GUID tab, enter the first part of the values noted in step 1. Open the BIOS with the UEFITool program (it is also located in the UBU folder). Save the file as new_vbios.dat and close the program.ĥ> Now you need to replace the OROM in the original BIOS. After a few moments of processing the file is ready. bsf file in the SKLKBL folder with the Intel BMP program.Īpply the original settings to the new vBIOS with: “BIOS Settings” -> “Apply All” by selecting “transfer.ssf”. Save the file and close it (Doing this you have removed the old vBIOS description).-搜索字符串“STRING$ Signon INtel(R)”,移除所有以这个字符串开头的字符行Ĥ> Open the “skl_1054.dat” file and the corresponding. Open “transfer.ssf” with notepad and remove ALL the line that starts with “STRING $ Signon Intel (R) …”. We have thus saved the settings of the original vBIOS that will be transferred to the new one. Once opened, save the settings from: “BIOS Settings” -> “Save All” by naming the “transfer” file with the extension. Take note and close without saving.-记下这串数字,例如1039ģ> Open the previously saved “vbios.dat” file with the Intel BMP program, using as a script file (.bsf) that of the corresponding version taken from the SKLKBL folder (in this example it is 1039). This number represents the version of the original vBIOS. these two files will allow the Coffee Lake microcode to be inserted semi-automatically.ġ> Open the BIOS to be modified with the MMTool program, select the “Option ROM” tab, in the table click on device 406, note the relative value of the “GUID section”, extract the OROM naming it “vbios.dat” and click on “apply”. In the folder UBU / modules / mCode replace the file “sel1151.bat” with the one with the same name attached to this post and in the subfolder 1151 insert the attached file: “cpu906EB_plat02_ver00000072_PRD_A08C2841.bin”. Leave a copy of the BIOS to be changed in the UBU folderĦ. Check that the MMTool.exe program has exactly this name (without spaces or numbers, possibly rename it) and insert it in the UBU folderĥ. Copy the VBIOS_and_BSF / SKLKBL folder into the UBU folderĤ. Install Intel BMP on the PC: it will be used to prepare the updated vBIOSģ. Unpack the UBU folder (v1.69.11.fix): this will be the main working folderĢ. Coffee Lake CPUs on Skylake and Kaby Lake motherboards The reason I'm trying to build this from source is to learn more about coreboot and in order to boot Qubes on the device by compiling with the disable clockgating and the new disable above 4g decode options.Fixing PCI-Express for Coffee Lake CPUs on Sky/Kaby Lake non-Asrock(and some new Asrock) motherboards The release MrChromebox works great and I'm impressed with the project.
