In particular, the distributed copy currently expects a Windows BMP file named bdlogo.bmp to be present on the MMC card and writes it to the display, then loads an operating system image from a file named nk.nb0 to RAM address 0xa0030000 and executes it.

Both of these are defined by the lines which resemble this:

#define CONFIG_BOOTCOMMAND "mmcinit; " \

"fatload mmc 0 a0000000 init.scr ; " \ "autoscr a0000000 ; "
