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!


Thanks,
Marcus
