===== Notes =====

Be ware that iPXE supports recursive variable expansion in shell commands.  Typing an interactive command such as ''echo ${dmesg}'' or ''param dmesg ${dmesg}'' is therefore a great way to exercise the memory allocator to the point of exhaustion.  Use ''show -q dmesg'' instead to show the recorded console output.
