class of the interface card when binding it into the system. This number
is displayed (in decimal notation) in the I column of ioscan output.
Bits 16 through 31 encode driver-dependent characteristics, which are
documented in Table C-4, “Bit Assignments for Tape Devices,” Table C-5,
“Bit Assignments for Disk and Magneto-Optical Devices,” Table C-6, “Bit
Assignments for Serial, Network, and Line Printer Devices,” and Table
C-7, “Bit Assignments for Miscellaneous Devices.” You can use these
tables to construct custom minor numbers, when you require a driver to
recognize or use specific or non-standard features of a device.
Table C-1, “Decimal, Binary, and Hexadecimal Equivalents,” may be
useful for translating bit assignments into hexadecimal digits.
