Hi. i have MSI H97M-E35 and Intel ark A380 and i need rBAR. i used last bios version (K.A ver), new users can not upload attachments but you can get it from msi site. i added FFS module. Then i used UEFIPatch. Then i fixed pad file with MMTool (PciBus, PciHostBridge, NvramSmi NVRAM whitelist unlock, Runtime). I did not flash modded bios because i afraid to have boot failure if i did something wrong in modding. And i have no flasher devise. so i request someone help to mod bios.
And abote enabling hidden 4G decoding - in txt from ifrextractor i have
"OneOf Prompt: “Above 4G Decoding”, Help: “Enables or Disables 64bit capable Devices to be Decoded in Above 4G Address Space (Only if System Supports 64 bit PCI Decoding).”, QuestionFlags: 0x10, QuestionId: 0x21, VarStoreId: 0x1, VarOffset: 0x1, Flags: 0x10, Size: 8, Min: 0x0, Max: 0x0, Step: 0x0
OneOfOption Option: “Disabled” Value: 0, Default, MfgDefault
OneOfOption Option: “Enabled” Value: 1
End "
and
"OneOf Prompt: “Legacy USB Support”, Help: “Sets Legacy USB function support.”, QuestionFlags: 0x10, QuestionId: 0x7, VarStoreId: 0xA, VarOffset: 0x1, Flags: 0x10, Size: 8, Min: 0x0, Max: 0x0, Step: 0x0
OneOfOption Option: “Enabled” Value: 0, Default, MfgDefault
OneOfOption Option: “Disabled” Value: 1
OneOfOption Option: “Auto” Value: 2
End "
both of them have VarOffset: 0x1. so when i use “modGRUBShell” i do not know what will it change, “Legacy USB Support” or “Above 4G Decoding” when i do “setup_var 0x1”
