Compiling ACPI v2.0 driver for Windows XP SP3 and Windows 2003 SP2 (x32/x64)

[Dietmar]

@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

Does BIOS have built-in UEFI Shell?

[Dietmar]

@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.

[Dietmar]

@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}
0x4BF1E         End {29 02}
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}
0x4BF31             One Of: CSM, VarStoreInfo (VarOffset/VarName): 0xCBE, VarStore: 0x1, QuestionId: 0x561, Size: 1, Min: 0x0, Max 0x1, Step: 0x0 {05 91 2A 21 2B 21 61 05 01 00 BE 0C 10 10 00 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.

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, 2024 by Dietmar

[reboot12]

Try this:

AmiSetupWriter.efi 0xCB3 0x0

[Dietmar]

@reboot12

Current Setup[0xCB3] is 0x1
