2.8 Adding Hardware
2.8.1 Adding Additional CPUs
When you install Windows Server 2003 on a multiprocessor computer with only one central processor unit
(CPU), the Windows Server 2003 Setup program will install a uniprocessor kernel on the computer. You can
add a second CPU to the computer by inserting the CPU in the motherboard, according to the manufacturer's
instructions, and restarting the computer. On reboot, the system will detect the additional CPU and will
replace the uniprocessor system drivers with the multiprocessor equivalents.
You can verify that the system sees the second CPU by opening the Performance window in Task
Manager. The Performance window should show graphs for each CPU. If the Performance window does
not display a graph for the second CPU, make sure it is fully seated and that no changes are required in
CMOS. Also, make sure the voltage regulators or other motherboard devices are in place and firmly seated.
