NOTE	When upgrading a processor or installing a second processor, the processor
	type and speed is automatically recognized by the BIOS. This means that no
	particular switch settings are required.
	Upgrading a single processor to a dual processor system on Windows NT
	and Windows 2000 platforms is made easier with the HP DualExpress!
	application which is included in the HP processor application kit.
	Installing a second processor is only advantageous when the software can
	make use of parallel activity. In particular, you need to be running a multi-
	threaded operating system that supports multiprocessing (one that is SMP-
	ready), such as Windows NT. The Windows NT operating system makes the
	best use of the Pentium III 32-bit architecture (though other operating
	systems will also show some benefit if 32-bit application programs are run).
	The two processors must have the same speed.
Configuring for	HP Kayak XU800 PC Workstations support Symmetric Multi-Processing
Multi-Processing	(SMP). When a second processor is added, it is automatically detected so
	there is no specific configuration required.
	The “mono-processing” mode has been implemented in order to support
	operating systems that rely on the “legacy” interrupt controller 82C59 and
	are not aware of I/O APIC controller operation. Refer to page 68 for further
	details.
Processor Clock	The 100/133 MHz Host Bus clock is provided by a PLL. The processor core
	clock is derived from the Host Bus by applying a “fix ratio”.
Bus Frequencies	There is a 14.318 MHz crystal oscillator on the system board. This frequency
	is multiplied to 133 MHz by a phase-locked loop. This is further scaled by an
	internal clock multiplier within the processor.
	The bus frequency and the processor voltage are set automatically.
