sis 5598 chipset

Does anyone know what the pci bus on this chipset would run if the fsb was 83mhz?

sis 5598 runs at 66 mhz so, pci multiplier = 1/2
83 / 2 = 41.2 Mhz.
the pci bus should be 41.2 mhz, unless the multiplier changes too.

Thanks, I managed to figure it out though, at 83mhz, it uses a 2/5 divisor, so the pci bus would be 33.
