NAME

bsod - Blue Screen of Death emulator

SYNOPSIS

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

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 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.

OPTIONS

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.

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.

XSCREENSAVER_WINDOW
The window ID to use with --root.

X RESOURCES

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.)

BUGS

Unlike the systems being simulated, bsod does not require a reboot
after running.
