In the 23-mm1 there is no such debug info. When the number of mem resource (for one Pnp device) defined by BIOS exceeds the predefined constant, the mem resource can't be added. But it won't report this case. In the 24-mm2 the PnP constant is raised and the debug info is added. When the number exceeds the predifined constant, it will give the debug info. Thanks. >
