Probably you're talking about the MIPS 4K series instead? > I have 128MB RAM on the system where 64MB is located at 0x00000000 > physical address and the other 64MB is located at 0x20000000. > > Also how is the address map for mips defined (highmem)? See . It's basically identical to 32-bit Intel. Ralf
