Miscellaneous Jumper Settings

Jumper block J2E2 enables server management write protect, configures cache
line size, disables the FRB, enables the FSB in common clock mode, applies
power to the pullups on the ISP chain for stand-alone programming, and selects
between using J1E2 or PCA8550 to set the host core bus ratio. By default, the
FSB is enabled in common clock mode, power is not applied to pullups, and the
J1E2 jumper determines the host core bus ratio.
