Any ideas what this jumper does? despite the markings, it does not change the FSB speed. Maybe it changes the PCI/AT bus speed? The Opti 82C822 is a PCI/VLB bridge controller chip.
I did notice to the left of the Opti 82C822 chip, there's a black box labeled "33.33333 M", I assume this is a crystal or something that controls the speed of the PCI bus. If that's true, then what does the jumper do?
