Notes
This option can only be
used if the PMC supports
PCI-X interface. The board
will automatically detect the
frequency of operation of
the PMC and the board will
negotiate accordingly. If the
PMC support PCI-X speed,
this switch can be
configured to run either 100
MHz or 133MHz frequency.
For I2C write-protect only.
Should be OFF for normal
operation.
