-Then you can play with the kernel inside the virtual serial console. You
-can launch @code{ls} for example. Type @key{Ctrl-a h} to have an help

 @example
-. /etc/linuxrc

-NOTES:
-@enumerate
-@item 
-A 2.5.74 kernel is also included in the archive. Just
-replace the bzImage in qemu.sh to try it.

-@item 
-In order to exit cleanly from qemu, you can do a @emph{shutdown} inside
-qemu. qemu will automatically exit when the Linux shutdown is done.
+When using the direct Linux boot, a disk image for the first hard disk
+@file{hda} is required because its boot sector is used to launch the
+Linux kernel.
  
-@item 
-You can boot slightly faster by disabling the probe of non present IDE
-interfaces. To do so, add the following options on the kernel command
-line:
+If you do not need graphical output, you can disable it and redirect
+the virtual serial port and the QEMU monitor to the console with the
+@option{-nographic} option. The typical command line is:
 @example
-ide1=noprobe ide2=noprobe ide3=noprobe ide4=noprobe ide5=noprobe
+qemu -kernel arch/i386/boot/bzImage -hda root-2.4.20.img \
+     -append "root=/dev/hda console=ttyS0" -nographic

-Lawton for the plex86 Project (@url{www.plex86.org}).
