 1.2 If you want to test PCI functionality with a 33Mhz PCI card, you will
     have to change the system clock from the default 66Mhz to 33Mhz by
     setting SW15[1]="OFF" and SW17[8]="OFF". After that you may also need
     double your platform clock(SW6) because the system clock is now only
-    half of its original value.
