NAME

  sizer	- Displays information about the system	or kernel, or creates a	sys-
  tem configuration file

SYNOPSIS

  /usr/sbin/sizer [-atm] [-b] [-c] [-gr] [-gt] [-implver] [-l] [-m] [-M]
  [-nfilename] [-p] [-pr] [-P] [-r] [-v] [-wc] [-wk] [-wp] [-wt] [-wu]

OPTIONS

  -atm
      Indicates	whether	an ATM (Asynchronous Transfer Mode) adapter is
      present.

  -b  Displays the name	of the file from which the running kernel was booted.

  -c  Displays the CPU type of the running CPU.

  -gr Displays an ASCII	string (terminated by a	line feed) that	specifies the
      size, in pixels, for each	graphics screen	that exists in the system.
      The information is displayed in the following format: width x height.
      For example, 1280x1024 specifies the default graphics screen on a	DEC
      3000 Model 500 system.  The resolutions of all the existing screens are
      displayed	on a single line in the	same order as the ROM ID strings that
      are displayed by the -gt option.	If no screens exist in the system,
      then 0x0 is displayed.

  -gt Displays an ASCII	ROM ID string (terminated by a line feed) for each
      graphics screen that exists in the system.  The ROM ID string identi-
      fies the graphics	controller for the screen.  Some controllers can
      manage more than one physical or logical screen.	If there are no
      screens in the system, then nothing is returned.

  -implver
      Displays the family name to which	the processor belongs. This can	be
      EV4, EV5 or EV6.

  -l  Displays the option for the small-memory system, or zero.

  -m  Displays the running kernel's module list, if that kernel	was linked at
      boot time. The information displayed is a	space-separated	list detail-
      ing the exact linker options and module names used to bootstrap link
      the running kernel.  If the running kernel is a statically linked
      image, sizer displays an empty string.

  -M  Displays the names of foreign kits that were linked into the running
      kernel at	boot time, including the name of the device from which they
      were loaded. The device name is the one known to the console.  (For
      example, on a DEC	3000 system, the device	name for a CD-ROM device is
      dka400). If the running kernel is	a statically linked image, sizer
      displays an empty	string.

  -n filename
      Creates a	configuration file.  The -n option creates a configuration
      file in /tmp/filename and	a shell	script named /tmp/filename.devs	that
      runs MAKEDEV to create devices such as Lcam. The system should be	run-
      ning the /genvmunix generic kernel to ensure that	all required devices
      and options are available. Note that disk	and tape device	special	files
      are created using	dsfmgr(8).


				       Note

	 You should run	doconfig to build a new	kernel.

  -p  Displays the number of available CPUs.

  -pr Displays the number of CPUs that are currently running on	the system.

  -P  Provides information on logical partitions.

  -r  Displays the name	of the root device.

  -v  Displays the operating system version string.

  -wc Displays the type	of workstation console.	 This number indicates
      whether a	graphics head was chosen as the	system console at boot time,
      or whether the alternate (serial interface) console was chosen.  If a
      graphics console was chosen, a zero (0) is returned to standard output.
      If an alternate console was chosen, a one	(1) is returned	to standard
      output.

  -wk Displays an ASCII	string that identifies the workstation keyboard	if
      one exists in the	system.	 For example, LK401 specifies the default
      keyboard on the DEC 3000 Model 500 system.

  -wp Displays an ASCII	string that identifies the workstation pointer if one
      exists in	the system.  For example, VSXXXAA specifies the	mouse on a
      DEC 3000 Model 500 system.

  -wt Displays the type	of workstation display.	 This number specifies each
      byte, which indicates a type of display, with one	byte used for each
      display. The limit is zero to four displays.

  -wu Displays the workstation display units.  This number specifies the "on"
      bits, which indicate the display units that exist	on the system.	For
      example, the return number 1 indicates that one display exists, the
      return number 3 indicates	that two displays exist, the return number 7
      indicates	that three displays exist, and the return number 15 indicates
      that 4 displays exist.  The limit	is zero	to four	displays.

DESCRIPTION

  The sizer program reports information	about the running system, including
  the name of the kernel file.	This program is	also used by the doconfig
  program to create a system configuration file.

  Note that if you use sizer with the -n option	to create a configuration
  file,	it may differ from the current configuration on	your system. For
  example, customizations may not appear in the	output from sizer.
