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 debug-
       ger 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,  doWin2K,
       doAmiga,  doMac,  doMac1, doMacsBug, doSCO, doAtari, doBSD, doLinux, doSparcLinux, doBlitDamage, and doSolaris.	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).
