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.
