Modded ACPI.SYS for Windows Vista x64

[ages2001]

Hi, everyone! I'm trying to install Windows Vista on Acer Travelmate P215-52G laptop (from 2020 era). It has Comet Lake chipset, i5-10210U CPU, Intel UHD Graphics iGPU, Nvidia MX230 GPU and 2x8 GB DDR4 RAM.

I tried modded ACPI.SYS files for Windows XP and 7 but none of them worked. WinXP ones gave 0x000000A5 ACPI BSOD. Win7 ones gave 0xc00000098 boot error. Also tried HEX editing 84 C0 75 1F to 84 C0 90 90 and 85 C0 78 2E to 85 C0 90 90 but gave 0x000000A5 ACPI BSOD.

Can anyone help me or have correct modded acpi.sys for vista x64? Thanks from now!

The patch that you are referring to

https://www.wincert.net/forum/topic/18176-vistaw2k8-x64-on-modern-hardware/

has to be applied to this exact version of acpi.sys 6.0.6002.24312 (vistasp2_ldr_escrow.180308-1636)

make sure you have the right version

 

But the necessary patch can be different for various hardware platforms

Do you have exact same installation ISO? I think mine is different.
