Updated and rebuilt OpenBIOS - still getting the same unhandled exception at the same place:
(gdb) l *0x00000000ffd10e54
0xffd10e54 is in cfetch (../include/openbios/stack.h:34).
29	typedef ucell phandle_t;
34	static inline void PUSH(ucell value) {
35		dstack[++dstackcnt] = (value);
36	}
37	static inline void PUSH_xt( xt_t xt ) { PUSH( (ucell)xt ); }
38	static inline void PUSH_ih( ihandle_t ih ) { PUSH( (ucell)ih ); }

What version of Milax are you using?  I downloaded the 0.4 ISO and all I get is "Unsupported Image Format" when I try to boot.
