The \playername{} has a built-in bootloader which performs the firmware update and can also access the hard drive via USB. The Rockbox bootloader can therefore be very minimalistic, as it does not require it's own USB mode. This makes it less dangerous to install the Rockbox bootloader as you can always restore it using the \playerman{} bootloader. \note{The Rockbox bootloader overwrites the original firmware, making it impossible to dual-boot.} \subsubsection{Installation} \begin{itemize} \item Download the Rockbox bootloader binary from \url{}. \opt{x5}{Use the \fname{x5v\_fw.bin} file if your \dap{} is a X5V. If it is a X5 or X5L, use the \fname{x5\_fw.bin} file.} \opt{m5}{Use the \fname{m5\_fw.bin} file.} \opt{m3}{Use the \fname{cowon\_m3.bin} file.} \item Copy it to the \fname{FIRMWARE} directory on your \dap{}. \end{itemize}
