a.Use opposite settings when using an 80300-BP Backplane from Cyclone Micro Systems or most other PCI-X backplanes (switches S7E1-3, S8E1-7, S4D1-1, 2, 3, 4).

b.On FAB C boards S8E2-3 is not a spare and it must be turned on.

c.Switches S4D1-1 and 2 have to always be opposite of each other.

d.Switches S4D1-3 and 4 have to always be opposite of each other.
