Download the first version of DreamOS: dreamos.img
+
+This version uses the VGA alphanumeric mode (80x24) only.
+
+On Linux, use
dd if=dreamos.img of=/dev/fd0 to write to a floppy disk.
+
+Once you boot the floppy, you will find yourself in the read-eval-print loop of the Dream Scheme Interpreter.
+
+DreamOS does not access the hard-drive, but you can write code that does if you want to (don't hold me responsible!)
+
+Files are stored on the floppy disk using a rudimentary flat file system.
+
+The file "bootstrap.scm" is loaded automatically when the Dream Scheme Interpreter starts.
+
+There is a primitive clone of the 'vi' editor, still under construction, coded in scheme in the file "edit.scm" (loaded automatically by "bootstrap.scm").
+
+Type
(edit "README") for example, and use the keys 'h', 'j', 'k', and 'l' for navigation, ':q' to quit.
+
+All of the source scheme files are included.
+
+
(load "make.scm") will recompile.
+
+
(sys-write-floppy) will save changes to floppy (and only then).
+
+
(sys-boot) will reboot.
+
+Have fun! :-)

Download the latest version of DreamOS: dreamos20080124.img
+
+Changes include:
+
+- SVGA graphics (1024x768) in 16 bit color. Does not work with all video cards. Good luck!
+- Integers have 32-bit magnitude (sign is stored separately).
+
+
+This version works on my Dell Inspiron 5000 and Dell Latitude CPi laptops, but I have not yet made efforts to insure
+it works on anything else.
+To recompile for VGA alphanumeric mode change the value of SVGA to #f in make.scm then proceed as described above.
