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, OS/2,
MacOS (MacsBug, Bomb, Sad Mac, and OSX), Atari ST, Apple ][+, and NCD X
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.
Specify which visual to use. Legal values are the name of a
visual class, or the id number (decimal or hex) of a specific
The duration each crash-mode is displayed before selecting
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.
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, doOS2, doHVX, 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
