+ *
+ * NOR and NAND boot options change bytes 6, 7, 8, 9, 11. The
+ * values are independent of the rest of the clock settings.

+ * All Sequoias & Rainiers select from two possible EEPROMs in Boot
+ * Config F. One for 33MHz PCI, one for 66MHz PCI. The following
+ * values are for the 33MHz PCI configuration. Byte 5 (0 base) is
