So what's going on in this video?

By now, we know the 32-bit (x86) edition can run on systems like Intel 14th Gen CPUs with full ACPI, NVMe, and USB 3.x support. But what about the XP x64 Professional edition, capable of addressing up to 128GB of RAM? The Problem? XP x64 is based on Windows Server 2003 and only supports ACPI 2.0 (partially) and modern motherboards use ACPI 6.x, causing a 0xA5 BSOD on boot on both XP x86 or x64 edition.

The Fix?

Patched ACPI.SYS & HAL.SYS (I used acpiSkull3new.sys from MSFN).

Integrated AHCI drivers (Intel/Win-Raid or Universal for AMD).

Optional NVMe/USB 3.x support (post-install or via ISO modding).

Step-by-Step Process:

Replace ACPI/HAL files (compressed via makecab).

Slipstream AHCI drivers with nLite.

Burn ISO to USB (via WinSetupFromUSB) or CD—but USB 3.x requires native 2.0 support (I used a NEC PCIe-to-USB 2.0 adapter).

Tested Hardware:

Intel 13th Gen (H610 motherboard): Works after manual ACPI.SYS replacement.

AMD Ryzen 9 3900X (X470): Flawless with Universal AHCI drivers.

BIOS updates? No issues—even with May 2025 firmware.

FAQs:

USB Install? Only with native 2.0 controllers (or USB 3.x baked into ISO).

AMD Support? Yes! Swap Intel AHCI for Universal drivers.

UEFI? It's doable, but I stick to CSM for multi-OS setups.
