40 * Most PCI cards are still 33Mhz, so in the presence of PCI, 33MHz
41 * is likely the desired value here, so that is now the default.
42 * The board, however, can run at 66MHz. In any event, this value
43 * must match the settings of some switches. Details can be found

46 * XXX -- Can't we run at 66 MHz, anyway? PCI should drop to
