Windows This is already a fairly old article, but I'm pretty confident it never made OSNews' front page. In this article, the author proves that Windows XP can be installed, and 'run', on processors with as little as 8MHz. "The target of this project was to find the weakest system where you can run Windows XP. Keep in mind, that Microsoft official requirements are a CPU with 233 MHz an 64 MB of RAM. But that had to be beaten!"

"XP seems to have number of kernels tuned for particular CPU/MOBO combinations on its installation cd. They are selected during installation but, I guess, can't be changed afterwards."

1. The HAL/kernel combo's are specific to 6 different scenarios on 32bit:

Standard PC - (Non ACPI/Non MP capable)
MPS Uniprocessor PC - (Non ACPI/MP capable w/1 CPU core at install time)
MPS Multiprocessor PC - (Non ACPI/MP capable with 2+ CPU's)
Advanced Configuration and Power Interface PC (ACPI/Non MP capable)
ACPI Uniprocessor PC (ACPI/MP capable with 1 CPU core or HT disabled at install time)
ACPI Multiprocessor PC (ACPI/MP capabe with 2+ CPU cores or HT enabled at install time).

2. You can change the HAL/Kernel combo quite easily through the device manager.
