Appendix A
A device file is required for each ACC MUX card that
will be accessed on the system. The naming convention
of the device file depends on the type of system being
used.
For systems that have no extended bus converter
addressing, the naming convention for the device files
is/dev/zmuxbYYsZZ. The YY and ZZ represent the
values that make up the hardware path to the card.
The YY represents the bus converter address and the
ZZ represents the card address.
For systems that do have extended bus converter
addressing, the naming convention for the device files
is /dev/zmuxBXXbYYsZZ. The XX, YY, and ZZ
represent the values that make up the hardware path
to the card. The XX represents the extended bus
converter address. The YY and ZZ represent the bus
converter address and card address respectively.
The format of the major number is 124 and the minor
number is shown below. Note that the uppermost byte
is always 0x40. Also note that the extended bus
converter address is 0 if the system has no extended
bus converter addressing.
