 NAME
      master - master device information table

 DESCRIPTION
      This file contains lines of various forms and is used by config to
      obtain device information that enables it to generate the
      configuration file (see config(1M)).

      Software drivers are defined as follows:

           Field 1        Device name, used in the user-specified dfile (8
                          characters maximum).

           Field 2        Handler name, used by the kernel to prefix
                          routines such as cs80_read, lp_write, and others
                          (8 characters maximum).

           Field 3        Element characteristics: Five bits make up the
                          mask

                               Bit 1:  card
                               Bit 2:  specified only once
                               Bit 3:  required driver
                               Bit 4:  block device
                               Bit 5:  character device (LSB)

           Field 4        Functions for the device; 12 bits make up the mask

                               Bit 1   option1 handler (Series 700 only)
                               Bit 2   dump handler
                               Bit 3   size handler
                               Bit 4   link routine
                               Bit 5   open handler
                               Bit 6   close handler
                               Bit 7   read handler
                               Bit 8   write handler
                               Bit 9   ioctl handler
                               Bit 10  select handler
                               Bit 11  seltru handler
                               Bit 12  C_ALLCLOSES flag (LSB)

           Field 5        Major device number if a block-type device;
                          otherwise -1.

           Field 6        Major device number if a character-type device;
                          otherwise -1.

      Aliases for names are defined as follows:

           Field 1        Alias name => product number (8 characters
                          maximum)
