Here's the table from page 159 and the preceeding paragraph on page 158 in
"Designing Cards and Drivers":

The ByteLanes field tells the computer which of the four NuBus byte lanes
to use when communicating with an expansion card's declaration ROM. NuBus
byte lanes are defined under "NuBus Bit and Byte Structure" in Chapter 7.
The value of ByteLanes is composed by setting a bit in the low nibble for
each byte lane used and then setting the high nibble to the low nybble's
complement. The location of the first bit set to 1 in the low nibble also
determines the address of the ByteLanes, and hence the starting address of
the format block. Table 8-2 shows all the possible ByteLabens values and
their corresponding format block starting addresses (where s is the slot
number). Notice that the ByteLanes byte always occupies the highest address
available in the byte lanes being used. The Slot Manager doesn't recognize
any ByteLanes values not shown in Table 8-2.
