This is untried! One problem is that with > 64MB in the system, the speculative memory probing performed by 3.x and older systems tends to kill the Thinkpad architecture dead (bad design!). I don't _think_ that this is the problem, however. The PnP probe happens at a different stage, and I suspect that this is some other, new form of brokenness. It would be very interesting if the original poster were to try a 4.0 snapshot on this machine. Note that I _have_ seen 3.x running on various thinkpad 770s, but not the Z. IBM were never able to ship me one, so I never got to fight with it either. -- \\ 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-stable" in the body of the message
