Everythign happens in the OS section - e.g.

BEGIN OS
  PARAMETER OS_NAME = uclinux
  PARAMETER OS_VER = 1.00.a
  PARAMETER PROC_INSTANCE = microblaze_0
  PARAMETER MAIN_MEMORY = ddr_controller
  PARAMETER LMB_MEMORY = ilmb_cntlr
  PARAMETER STDOUT = console_uart
  PARAMETER STDIN = console_uart
  PARAMETER TARGET_DIR = 
/mnt/home2/jwilliam/dist-test/uClinux-dist/linux-2.4.x/arch/microblaze/platform/uclinux-auto
END

Can you post your "OS" section from your MSS file?  The peripherals 
named in the MAIN_MEMORY and LMB_MEMORY must correspond to actual 
instances in your hardware (MHS).  STDOUT and STDIN are the same as in 
the "standalone" BSP - it's just for the bootloader.

John
