[Request] MSI H97M-E35 rBAR mod and 4G Decoding

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”

But one has VarStoreId: 0xA and another - VarStoreId: 0x1.

Modded grub will change the one with VarStoreId: 0x1 unless VarStore is specified.

Thanks

Hi @ivan49,

There are several hidden / advanced menus in the BIOS setup. With one having Above 4G

Key combinations on startup or in the BIOS setup can get you into these menus on MSI laptops, not sure about desktops.

In the bios menu

Right Shift + Right Ctrl + Left ALT and F2

Or something like that.

Try doing a google search for MSI advanced bios key combo

good luck
