Warning W2520 - The PCI bus speed is too high. The PCI bus speed should not be increased over 36MHz. While most PCI cards may work, some hard drives, CD-ROMs, network cards and other cards may not and you could get data corruption without knowing.
Fix: Make sure the FSB is not higher than 68MHz. While 75, 83 or 90MHz give you higher performance the data loss may not be worth it. If the chipset supports asynchronous PCI, enable this option to keep the speed at 33MHz, independent of FSB.
