Which is bad, because most boards only have tin contacts on their sockets. But this is a different story. Wrong contacts can cause you more failures over time. One Point is that my Hardware Reference Manual shows a maximum of 512M memory (4x 16Mx72). Christian tried modules with doubled size. Another Point is that especially SDRAM can come in different organisations which are not transparent to the system chipsset and system initialisation software. It is possible, that SRM or the hardware just can't handle the organisation of the modules in question - especially as the board was not designed to use modules of that size. -- B.Walter COSMO-Project http://www.cosmo-project.de ticso@cicely.de Usergroup info@cosmo-project.de To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-alpha" in the body of the message
