I've upgraded the board bios, changed to a new memory vendor, etc etc. Still have exactly the same symptoms, and from what rob said it would seem this problem is specific to freebsd, and not any particular motherboard. Is anyone actually running a freebsd machine with more than 512 megs of memory? Anyone have a clue at all as to why freebsd can't support a gig of ram? windblows seems to have no problem (which doesnt help me much) Thanks, Sam To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-hardware" in the body of the message
