Use this task to activate or deactivate cores using the BIOS Setup Utility.
If a core is deactivated in BIOS, it cannot be activated in the OS.
When you activate or deactivate cores in BIOS, it applies the change to all sockets in the server equally.
The BIOS Setup Utility provides the ability to select how many cores are active (1 through 15). It does not allow you to select individual cores or ranges of cores.
