Here is the guide/post I used to remove SLIC: https://forums.mydigitallife.net/th...c-in-newer-asus-uefi.31404/page-7#post-849131 I used the official /unmodified version of the same version I had installed - and erased all blocks to erase the existing SLIC. The "issue" is with Step 2 of the guide: "2. In any x64 Windows OS download amiflash.zip and extract Aptio Afuwin64 folder. Open it and run AFUWINGUI.EXE. Click Open and select official or your modded (doesn't matter) .cap file. On the opened SETUP tab uncheck all boxes and check only box #2 under "Non-critical block" caption. Press Flash and wait till it's green." I have no idea what non-criticial block (aka "box") to erase, so in the end I checked and erased them all (Asus X299). That certainly erased the SLIC but also erased all unique DMI data as well... so if you need to save it and then recreate it all.
Sorry I meant AMI - see the guide above Anyway, likely Serge has a better method - just wanted to post my experience, as I said it does erase SLIC at the expense of DMI data so you need to decide whether the aggro is worth it ;(
When I run the AFUWINGUIx64.exe using latest version of Aptio_V_AMI_Firmware_Update_Utility. It locks my entire computer have to reboot to recover. Only way I can use Aptio_V_AMI_Firmware_Update_Utility is with AFUDOS in dos mode.
@Viradus Which Gigabyte motherboard is it? You may need to untick the following two options under Phoenix Tool's advanced section before modding: Only alter RSDT and XSDT tables Only alter tables in the main ACPI module
