I use qemu-0.14.1, qemu-system-ppc -M prep -cpu $CPU -bios my_bios -kernel my_kernel That works fine on a 604 (CPU=0x00040103) - but does not on an emulated 7400 (CPU=0x000c0209) or 7450 (CPU=0x80000201). I found that the emulator jumps to 0x00000c00 instead of 0xfff00c00. Probably this is due to a wrong setting in target-ppc/translate_init.c: init_excp_604() correctly sets env->hreset_vector=0xfff00000UL; but init_excp_7400() says env->hreset_vector=0x00000000UL; which seems wrong. (the 7400 manual says a hard-reset jumps initializes the prefix to 0xfff00000.) Likewise, init_excp_7450() (and probably other, related CPUs) are wrong. Indeed, when I change the value in init_excp_7400() to 0xfff00000UL then everything works as expected for me.
