+\begin{itemize}
+ \item It is also possible to boot an uncompressed kernel:\\
+ \code{arch/<arch>/boot/Image}
+ \item This could be a worthy solution if you have a slow CPU
+ and fast I/O, or if you're booting Linux in an emulated
+ machine (hardware or software emulator).
+ \item On U-Boot on ARM, you won't be able to boot with the
+ \code{bootz} command. You will need to use \code{bootm}
+ and a \code{uImage} file.
