+/** @page generic_pc Generic PC based bootloader
+
+This platform acts as a generic PC based bootloader. It depends on at least
+one boot media that is connected locally (no network boot) and can be
+handled by the regular BIOS (any kind of hard disks for example).
+
+The created @a barebox image can be used to boot a standard x86 bzImage
+Linux kernel.
+
+Refer section @ref x86_bootloader_preparations how to do so.
+
+How to get the binary image:
+
+Using the default configuration:
+
+@code
+make ARCH=x86 generic_defconfig
+@endcode
+
+Build the binary image:
+
+@code
+make ARCH=x86 CROSS_COMPILE=x86compiler
+@endcode
+
+@note replace the 'x86compiler' with your x86 (cross) compiler.
