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.
