@reboot12

I did this already. But there is also no possibility in this Bios, to disable the onboard (cpu) graphic.

But I can see Bios on screen with my external Geforce GT 730 card

Dietmar

Does BIOS have built-in UEFI Shell?

@reboot12

No. I found only this:

Launch EFI Shell from Filesystem device

You probably have UEFI Variables Protection password protected:

I do not have such a value in my mobo 8 Gen NVRAM. I recently unlocked the edition of DMI in NVRAM

Can someone enlighten me on what this thread is about? I have ACPI 2.0 enabled in BIOS and XP x64 runs on this machine, which has old 2008 ASUS M3N78 motherboard. Except if you set XP in a way so the mouse can wake up computer from standby, then fans keep running in "standby" mode.

@UCyborg

It's about fixing XP's acpi.sys driver to work with newer hardware.

@reboot12

I changed the original value in this Bios

09 07 04 00 00 00 00       ==>

09 07 03 00 20 00 01

 

 

0x4BF11     Form: CSM Configuration, FormId: 0x29AB {01 86 AB 29 15 21}
0x4BF17         Subtitle: Statement.Prompt: Compatibility Support Module Configuration, Flags: 0x0 {02 87 17 21 00 00 00}

0x4BF20         Subtitle: Statement.Prompt: , Flags: 0x0 {02 87 02 00 00 00 00}
0x4BF27         End {29 02}
0x4BF29         Suppress If {0A 82}
0x4BF2B             QuestionId: 0x11F0 equals value 0x1 {12 06 F0 11 01 00}

0x4BF42                 Default: DefaultId: 0x0, Value (8 bit): 0x0 {5B 06 00 00 00 00}
0x4BF48                 One Of Option: Disabled, Value (8 bit): 0x0 {09 07 04 00 00 00 00}
0x4BF4F                 One Of Option: Enabled, Value (8 bit): 0x1 (default MFG) {09 07 03 00 20 00 01}
0x4BF56             End One Of {29 02}

 

and flash with EEpromer. Compi starts, but still no CSM can be choosen in Bios

Dietmar

PS: This is the modded Bios.

Via normal Bios flash I was told, that Secure Flash failed, so EEpromer.

Can you tell me the sequenz in EFI commandline from before,

so that I can test, if my modd happened and if the Lock is gone

Hi,

Has somebody an idea, how to make the NVRAM (NVRAM sits on Bios chip???) write enabled

Dietmar

EDIT: Can this be down with the UEFI file for to enable CSM

SceEfi64.efi /bt bla bla bla

SceEfi64.efi is the UEFI variant of the AMISCE tool.

 

Edited June 2, 20242 yr by Dietmar

Try this:

AmiSetupWriter.efi 0xCB3 0x0

@reboot12

Current Setup[0xCB3] is 0x1

gRT-->Setupvariable call returned  Write Protected.
