Hello, i have a HP Notebook 15-R206NG from a colleague, was shipped with Windows 8.1, he wants to downgrade to Windows 7. It has Insyde EFI, latest version is installed (F.40, link to bios: http://ftp.hp.com/pub/softpaq/sp76501-77000/sp76922.exe). What i tried: -Advanced menu in bios not possible, neither pressing keys (fn+f1+shift, typing A D V) nor unlocking MPM with lockmpm.bat or SMC.bin. But that doesn't matter. -i did this mod with changed PCID, using nbdmifit 2.0F: https://forums.mydigitallife.net/th...date-Utilities?p=131386&viewfull=1#post131386 and it activated SLIC and deactivated MSDM. But i have failure from SLIC Toolkit: "Dump OK! (but slic oem id or digital signature error)" and digital signature "Error", Marker "Invalidated". Please see RWE-report and Toolkit-error.bin: https://www.sendspace.com/file/yiab8p So, any ideas to get the complete/correct SLIC-table in BIOS?
