       bsod - Blue Screen of Death emulator


       bsod  [-display  host:display.screen]  [-foreground color] [-background
       color] [-window] [-root] [-mono] [-install]  [-visual  visual]  [-delay


       The bsod program is the finest in personal computer emulation.

       bsod steps through a set of screens, each one a recreation of a differ-
       ent failure mode of an operating system.  Systems depicted include Win-
       dows  3.1,  Windows  95,  Windows  NT, MS-DOS, AmigaDOS 1.3, Linux, SCO
       UNIX, BSD UNIX, HPUX, Solaris, Tru64, VMS, HVX/GCOS6, IBM OS/390, MacOS
       (MacsBug,  Bomb, Sad Mac, and OSX), Atari ST, Apple ][+, and NCD X Ter-


       bsod accepts the following options:

       -window Draw on a newly-created window.  This is the default.

       -root   Draw on the root window.

       -mono   If on a color display, pretend we’re on a monochrome display.

               Install a private colormap for the window.

       -visual visual
               Specify which visual to use.  Legal values are the  name  of  a
               visual  class,  or the id number (decimal or hex) of a specific

       -delay delay
               The delay between displaying one crash and another.

       -only which
               Tell it to run only one mode, e.g., -only HPUX.


       DISPLAY to get the default host and display number.

               to get the name of a resource file that  overrides  the  global
               resources stored in the RESOURCE_MANAGER property.


       Notable  X  resources  supported  include  the following, which control
       which hacks are displayed and which aren’t.  doWindows, doNT,  doWin2K,
       doAmiga,  doMac,  doMac1,  doMacsBug,  doMacX,  doSCO,  doAtari, doBSD,
       doLinux, doSparcLinux, doHPPALinux,  doBlitDamage,  doSolaris,  doHPUX,
       doApple2,  doOS390,  doTru64, doVMS, doMSDOS, and doHVX.  Each of these
       is a Boolean resource, they all default to true,  except  for  doAtari,
       doBSD,  doSparcLinux, and doHPPALinux, which are turned off by default,
       because they’re really not all that interesting looking unless you’re a
       fan of those systems.

       There  are  command-line options for all of these: e.g., -bsd, -no-bsd.
       (Also note the -only option.)


       Unlike the systems being simulated, bsod  does  not  require  a  reboot
       after running.
