For the most part, Windows 2000 Setup is remarkably easy to use on a single machine. Boot from the CD and follow the prompts. But the process gets a little tricky if you have BIOS problems that need to be worked around. That?s especially true on systems with incompatible implementations of ACPI. Three function keys (only one of which is documented) let you control setup options, including the machine type. Do you know what these three options are and how to use them?
