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 Mi‐
crosoft's Windows 95 and Windows NT, Commodore-Amiga's AmigaDOS 1.3,
SPARC Linux, SCO UNIX, the Apple Macintosh (both the MacsBug debugger
and the rarer "Sad Mac"), and the Atari ST.
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 delay between displaying one crash and another.
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, doAmiga,
doMac, doMacsBug, doSCO, doAtari, doBlitDamage, doSparcLinux, and doS‐
Solaris. Each of these is a Boolean resource, they all default to
true, except for doSparcLinux and doAtari, which are turned off by
default, because they're really not all that interesting looking unless
you're a fan of those systems. There aren't command-line options for
these, so to change them, you'll need to add entries to your .Xdefaults
file, or use the -xrm option. For example, to tell bsod not to show
the NT crash:
bsod -xrm '*doNT: false'
Unlike the systems that the images are borrowed from, bsod does not
require a reboot after running.
bsod should also emulate more systems, but systems with interesting
crash graphics are not as common as one might hope.
One I'd really like to see is a Unix system getting a kernel panic,
rebooting, and running fsck(8).
