    "what are this map files..."

    Maybe Google would know what map files are?

    Maybe Keil documentation would know what map files are?

    "i am not using any external RAM"

    The same moment you did switch to large memory model you started to use external memory - you did read up on the meaning on large memory model? You have read up on the different memory areas of the 8051 architecture?

    Don't you find it hard to write programs for a tiny microcontroller chip if you don't first spend some time to learn the capabilities of the microcontroller? At least I would not know how to use a new processor without first spending time with datasheets, user manuals and maybe additional architecture documents.
