Yes.

There is no way to determine what is or is not "clealy Windows' fault". If the hardware corrupts data, then there is NOTHING that can be done about it.

I would expect that if I were to go purchase memory certified for this board, it would work. On the other hand, I have on several occasions failed entirely to install any of several different Microsoft operating systems on this board; by your criteria I would assert that the board is entirely unsuited for sale as a product at all. -- \\ Give a man a fish, and you feed him for a day. \\ Mike Smith \\ Tell him he should learn how to fish himself, \\ msmith@freebsd.org \\ and he'll hate you for a lifetime. \\ msmith@cdrom.com To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-smp" in the body of the message
