Bus Arbitration Fairness controls whether the adapter will release control of the bus when it has been using it exclusively
This selects the DMA channel the adapter will use to transfer data.
<"Level 14">, 13, 12, 11, 10, 9, 8, 7, 6, 5, 3, 2, 1, 0
I/O Address allows you to choose the I/O address for the adapter Each adapter must have a unique address range.
<"7140-714F">, 7150-715F, 7540-754F, 7550-755F, 7940-794F, 7950-795F, 7D40-7D4F, 7D50-7D5F
RAM Address Range
RAM Address Range is 8 possible blocks of memory that can
be assigned for accessing the RAM located on this FDDI adapter.
<"C0000-C01FF">, C4000-C41FF, C8000-C81FF, CC000-CC1FF, D0000-D01FF, D4000-D41FF, D8000-D81FF, DC000-DC1FF
This allows you to choose the interrupt level the adapter will use
<"Interrupt 10">, 14, 15, 9
An IBM FDDI Extender adapter may be present in one of the adjacent slots even though the 'View Configuration' or 'Change Configuration' window indicates that the slot is 'Empty'.
To determine if an IBM FDDI Extender adapter is present in an adjacent slot, run the adapter's diagnostics or visually check the adjacent slots.
