NAME

bsod - Blue Screen of Death emulator

SYNOPSIS

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

DESCRIPTION

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 Microsoft'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.

OPTIONS

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: 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 delay between displaying one crash and another.

ENVIRONMENT

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.

X RESOURCES

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 doSSolaris. 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'

BUGS

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).
