[REQUEST] Keyboard mod for InsydeH2O BIOS Lenovo S400T

[wilco_sg]

Let me reboot and take a pic.. 1 min

Hi,

I need a mod to change the keyboard behavior.
There is a setting in the BIOS, Hotkeys Mode:

it looks like this picture taken from another laptop

[wilco_sg]

Erm.. I took the pic myself on my Lenovo S400T, it is under Configuration.
Do you see Configuration?

[Falseclock]

Nope,

I even do not see such words combination in translation files.

Are you sure you sent correct bios dump?

[wilco_sg]

I have only 1 notebook. I took the dump using the Universal BIOS Backup ToolKit 2.0.
Did I do it wrong? I will gladly do it again if you can guide me with some links or instructions.

[Falseclock]

hm... finally found it.. but in a strange place

now at work, later will look at

[wilco_sg]

Thanks!!

so your bios have some additional menu which is a part of another setup program

here is dumper with debug information.

Your Configuration submenu is a part of Boot menu.

EFI_IFR_VARSTORE_EFI_OP triggers another program to build sub-sub menu

Code:

╔════════════════════════════════════════════════════════════════════════════════════════════════════════════════════╗
║ FormSet: 'Boot'                                                         GUID: a04a27f4-df00-4d42-b552-39511302113d ║
╟────────────────────────────────────────────────────────────────────────────────────────────────────────────────────╢
║ VarStore Id: '0x1234', Size: '900', Name: 'SystemConfig'                GUID: a04a27f4-df00-4d42-b552-39511302113d ║
╚════════════════════════════════════════════════════════════════════════════════════════════════════════════════════╝
  EFI_IFR_VARSTORE_EFI_OP

typedef struct _EFI_IFR_VARSTORE_EFI {
   EFI_IFR_OP_HEADER        Header;
   EFI_VARSTORE_ID          VarStoreId;
   EFI_GUID                 Guid;
   UINT32                   Attributes;
   UINT16                   Size;
   UINT8                    Name[1];
} EFI_IFR_VARSTORE_EFI;

my dumper does not read alien GUID forms. But tonight will try to decompile this part of code and will check how it works.

but it seems key remaping stored somewhere inside and need to patch driver, cause bios itself does not operate with hardware buttons

Ok, I can roughly follow what you are saying, just let me know if you need to me extract any more files... thanks!

[wilco_sg]

falseclock, did you find a way? thank you
