sys_attrs_bparm(5)
NAME
  sys_attrs_bparm - bparm subsystem attributes

DESCRIPTION
  This reference page lists and describes attributes for the Boot Parameters
  (bparm) kernel subsystem. Refer to the sys_attrs(5) reference page for an
  introduction to the topic of kernel subsystem attributes.

  boot_dev
      Identifies the device from which the system was last booted.  This
      attribute corresponds to the console firmware environment variable with
      the same name.  Do not modify this value, which is set when the system
      boots.

  boot_osflags
      A combination of flags that controls the boot loader and kernel. This
      attribute corresponds to the console firmware environment variable with
      the same name. Values for the variable are:

      a	      Boot to multiuser mode. By default, the kernel boots to
	      single-user mode.

      k	      Enable the kdebug debugger to debug the kernel. By default,
	      kdebug is not enabled in the kernel.

      d	      Produce full dumps when the system crashes. By default, partial
	      dumps are produced.

      i	      Prompt for an alternate kernel and special arguments when the
	      system is booted. By default, no questions are asked.

      Set boot_osflags only at the console prompt or by using the consvar
      utility.

  bootdef_dev
      Identifies the boot device to be used when one is not included in the
      boot command line. This attribute corresponds to the console firmware
      environment variable with the same name. Set bootdef_dev only at the
      console prompt or by using the consvar utility.
