Hello, I am currently requesting an Acer Aspire One AOA150 InsydeH2O bios unlock with all options unlocked because I want to install Windows 2000 Professional on the computer, but can't install it because it always freezes at "Setup is Starting Windows 2000 whenever I install with "ACPI Multiprocessor PC." So, if you could help me, I'd really appreciate it.

Windows 2000 includes two system cores that are specifically designed for ACPI compatible machines. These are ACPI Uniprocessor PC and ACPI Multiprocessor PC. The second is often the only way to get a full set of power management functions on multiprocessor systems, in particular such a convenient function as automatic shutdown of the machine. However, even here it is not so simple. When installing the ACPI core, all other devices in the system are connected via ACPI, which can be easily verified by sorting them into the Device Manager "By Connection":
In this regard, some problems may arise. In particular, if your system is still not fully compatible with ACPI (for example, at the BIOS level), then when installing the ACPI core, the system will simply refuse to boot in any modes, including Safe Mode, and through pre-saved Hardware Profile. The download will stop immediately after the bootloader starts (it loads when the strip at the bottom of the screen fills on a black background).
Moreover, even the presence of a fully ACPI-compatible system does not guarantee that Windows 2000 will boot after changing the kernel to ACPI xxxprocessor PC. The reason for this is that not all devices will be able to initialize correctly through the ACPI core, or not all of them will have ACPI compatible drivers. The result of this can be a wide variety of error messages, the most common of which is "Inaccessible boot device" (the boot disk is unavailable). Therefore, before rushing to change the kernel to ACPI, ensure that you can boot with the old kernel. And, if the system passes the initial boot stage, and "dies" after drawing a color image that waits for every Windows 2000 boot, it means that the system is most likely compatible with ACPI. But in order to make it work nominally, you will have to rearrange the entire system. At the same time, ACPI functions in the BIOS must be enabled during installation. In this case, the system itself, already during the installation process, will determine that the system is compatible with ACPI, and all devices will be installed taking this fact into account.
