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 emula
tion.
bsod steps through a set of screens, each one a recreation
of a different failure mode of an operating system. Sys
tems depicted include Microsoft's Windows 95 and Windows
NT, Commodore-Amiga's AmigaDOS 1.3, SPARC Linux, SCO UNIX,
HPUX, IBM OS/360, the Apple Macintosh (both the MacsBug
debugger and the rarer "Sad Mac"), the Atari ST, and the
Apple ][+.
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. - -only which
- Tell it to run only one mode, e.g., -only HPUX.
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_MAN
AGER property.
X RESOURCES
Notable X resources supported include the following, which
control which hacks are displayed and which aren't.
doWindows, doNT, doWin2K, doAmiga, doMac, doMac1, doMacs
Bug, doMacX, doSCO, doAtari, doBSD, doLinux, doSparcLinux,
doBlitDamage, doSolaris, doHPUX, doOS390, and doApple2.
Each of these is a Boolean resource, they all default to
true, except for doAtari, doBSD, and doSparcLinux, which
are turned off by default, because they're really not all
that interesting looking unless you're a fan of those sys
tems.
There are command-line options for all of these: e.g.,
-bsd, -no-bsd.
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.
