With stock BIOS, it is the other way around. This standby state is disabled when S0 low power idle is supported. The following sleep states are not available on this system: Standby (S0 Low Power Idle) Network Connected ![]() Now it shows in Windows: The following sleep states are available on this system: I’m on Alder Point Desktop (Gigabyte Z690 Aorus Elite DDR4). This way, I have been able to enable S0 power state (Modern Standby) by setting ‘Low Power S0 Idle Capability’ to enabled. Now, you can imagine that is not the most efficient workflow for testing but at least it works. ![]() ![]() My workaround for this is to edit NVRAM vars in the ROM image and then flash the image (instead of changing the variable directly in NVRAM from UEFI shell or in BIOS setup). These are ‘Setup’, ‘AMITSESetup’, ‘PchSetup’ to name a few. I hit another brick wall there because the varstores that I need to edit, are write protected. I don’t know if this is because I am doing something wrong, or if it is because of the custom menu that this BIOS has.Īnother, more successful, avenue for me has been to completely ignore the BIOS setup and its options and instead to modify UEFI NVRAM variables. In the meantime, as I said in my first post, I hit a brick wall with trying to unlock hidden options using the free UEFI Editor tool. I found one success here in which the BIOS options were confirmed unlocked/unhidden, but they didn’t say how they did it. It makes me wonder, if anybody has even been able to mod a Z690 BIOS?Īs you can see: unfilled request here, and here unfilled #2, another unfilled here. I searched the forum for “Z690” and I see lots of requests for modding but all but one request are unfilled/unanswered. Has anybody successfully used AMIBCP to mod a Z690 BIOS? And which version did you use? Or are people using free tools? I see in the screenshots, that they use AMIBCP to mod older BIOS versions (for Z390, etc.), but what about Z690? But I would like to know, which tools people are using to successfully mod Alder Lake/Alder Point BIOS ROMs. I fully understand that the tool cannot be legally made available here. I have not seen any indication that someone claims they have the new AMIBCP Pro or have used it to edit a BIOS. Then Sweet_Kitten points me to the AMIBCP Pro tool that nobody has access to, afaik. In my first post, I was using a free tool (Aptio V UEFI Editor). If you read my posts, you will see that I did not ask for a link to the tool, because I understand, that it cannot be legally obtained by anyone here, unless they work for a hardware manufacturer. What about asking the Company AMI? I am pretty sure, that AMI will be pleased about your request. Lastly, once I have both the new 0x104 microcode and the old microcode both open in HxD, how do I know what to replace? (I am currently trying to figure this out from these two tutorials: Perhaps I am supposed to infer file size from the last offset line (which is 0014B400)? IT SEEMS I CAN CHECK THE SIZE IN UEFI TOOL… it gives “full size,” “header size,” and “body size,” and I’m not sure which is relevant. ssIt also talks about checking whether the two microcode files are different sizes, and I’m supposed to be able to see this in the hex editor? I used the “fastforward” button in the data inspector window on the right in HxD, but I don’t see anything obvious indicating file size. I then have successfully opened it in HxD hex editor where I see all the hex values.Īt this point I am the tutorial starts talking about a “CPU microcode repository” and I’m not sure whether that is even relevant to what I’m trying to do, which is to replace the newer bios microcode with the 0x104 microcode. The tutorial says to open the master microcode file in HxD editor, so I’m assuming that’s what this file is. Per the tutorial, I right-clicked it and “extract body” and saved it as File_Raw_Microcode_body.raw. I have opened every single section of the list and there is only one microcode file (and it matches the GUID(?) from the tutorial, so I’m sure I have the right thing. So I have opened the bios file (with the microcode I want to edit) into in UEFITool NE Alpha 51. Retrieved January 22, 2024.Apparently I am supposed to find a 0x104 Intel microcode and replace it into bios. ![]() Forensic Science International: Digital Investigation.
