2.3.2.4 System Clock Combinations

The major clock combinations for an Apollo Pro133A based system are listed in Table 8. Clock frequencies for the AGP clock
and PCI clock are 66MHz and 33MHz respectively. Various clock combinations for the CPU clock and the SDRAM clock are
determined by power-up strap options on MAB12# and MAB8#.
