With the bus/core ratio switches in the default position, the system ROM automatically detects
the speed of processors installed on both processor buses. The processors automatically run at
the speed of the slowest processor installed in the server.
The default setting for the bus/core ratio switches has all switches in the Off position. Compaq
recommends that the bus/core ratio switches remain on the default setting to allow the system
ROM to detect the correct speed automatically. If necessary, the bus/core ratio switches can be
manually set to force processor speed settings. See "Processor Board Bus/Core Frequency Ratio
Switch Settings" in Chapter 4 for manual bus/core frequency switch settings.

CAUTION: If the bus/core ratio switches are set to a speed higher than the slowest processor,
the server will not boot. Failure to properly set the bus/core ratio switches could damage the
server and void the warranty.
