Figure 21. Relation Map of Base Proto and Proto Extension Files
Base Proto Files:
The Base Proto files are platform specific. They contain
libraries, non-device-related commands and ODM data files relevant to a specific
platform. They are named with the platform type as their prefix:
For microchannel-based RS/6000 systems:
rs6k.disk.proto, rs6k.tape.proto, rs6k.cd.proto, rs6k.tok.proto,
rs6k.ent.proto, rs6k.fddi.proto
For SMP systems:
rs6ksmp.disk.proto, rs6ksmp.tape.proto, rs6ksmp.cd.proto,
rs6ksmp.fddi.proto, rs6ksmp.tok.proto, rs6ksmp.ent.proto
For PCI-based RS/6000 systems:
rspc.disk,proto, rspc.cd.proto, rspc.tape.proto, rspc.tok.proto,
rspc.ent.proto
Note!
The
rspc.tape.proto
proto file is new in AIX Version 4.1.4 and allows the
creation of a bootable tape on PCI-based RS/6000 systems.
Proto Extension Files:
Combined with the Base Proto files, Proto Extension files
are also used for dynamically creating the prototype file. The platform-specific
information is incorporated so that only those extension files relevant to the given
platform type are used. However, some of the extension files are used for more
than one platform, and some are used for only one specific platform.
To specify which platform needs which types of extension files, they are placed in
groups specified as part of their file names. The platform-specific information for
the proto extension file groups are maintained in a configuration file which has a
.pcfg extension. The
.pcfg
file is prefixed with the platform type, and it contains the
list of
device groups
which are valid for a given platform.
