bsod - Man Page

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

The bsod program is the finest in personal computer emulation.  

bsod steps through a set of screens, each one a recreation of a different failure mode of an operating system.  Systems depicted include Windows 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, OS/2, MacOS (MacsBug, Bomb, Sad Mac, and OSX), Atari ST, Apple ][+, VMware and NCD X Terminals.

bsod accepts the following options:

--window

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

--root

Draw on the root window.

--window-id number

Draw on the specified window.

--mono

If on a color display, pretend we're on a monochrome display.

--install

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 visual.

--delay delay

The duration each crash-mode is displayed before selecting another.

--only which

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

--fps

Display the current frame rate and CPU load.

DISPLAY

to get the default host and display number.

XENVIRONMENT

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

XSCREENSAVER_WINDOW

The window ID to use with --root.

Notable X resources supported include the following, which control which hacks are displayed and which aren't. doWindows, doNT, doWin2K, doWin10, doRansomware, doAmiga, doMac, doMac1, doMacsBug, doMacX, doSCO, doAtari, doBSD, doLinux, doSparcLinux, doHPPALinux, doBlitDamage, doSolaris, doHPUX, doApple2, doOS390, doTru64, doVMS, doMSDOS, doOS2, doHVX, doVMware, and doATM. 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.
