Which bootloader are you using? I use PMON (provided from NEC). PMON load from serial or ethernet to 0x80100000. This is specified by arch/mips/Makefile. When you type "g", PMON is jumped to kernel_entry. When PMON does not recognize kernel_entry, you can investigate System.map and can specify an address. Yoichi
