 I didn't bother to licence it as it is so small, but consider it is under some sort of creative commons that allows redistribution and modification. <br /> -- Alexandre Buisse &lt;nattfodd@gmail.com&gt;

+Comments from Marcus Brinkmann:

+> Thanks a lot for that. Some comments:

+>     $ ../configure --with-s0-linkbase=0x40000 --prefix=/l4
+>
+> I'd recommend to explain how to use `--without-com0` here (or whatever it is called, don't remember) to choose VGA output, or how to configure the serial port. If you use vga, no `-o` option to laden and wortel should be used so you get all output on vga (but of course you can also mix it, whatever you want).

+> Serial 1 is currently going to be used for remote debugging of userland apps.

+> QEMU supports up to four serial ports, I use: `-serial stdio` and `-serial pty` and then I get the debugging output and kernel debugger in the terminal I started qemu in, and can use the pty for remote debugging with gdb (the latter doesn't work yet).

+> Next:
+>
+>     You should modify the first three lines to :
+>      ARCH=ia32
+>      CPU=i586
+>      PLATFORM=pc99
+>
+> I never did that. I did change the menu item Processor Type to Pentium1 though. Maybe it has the same effect (and then your document would be a bit redundant here).
+>
+> Somebody should at some point document all those menu options, some are quite useful for debugging!
