FreeBSD/alpha is not currently > SMP-capable and will only use one CPU. The NCR quirk should be moved out of the monet section, it applies to all multi-hose machines (eg DS20, dp264 & UP2000). The DS20 ships with an NCR card in a pci slot on hose1, so one has to open the case & move the board to get FreeBSD booting. I think that the DS20's nickname is "goldrush" Notice the above edits about having 2 hoses, 3 pci slots / hose Drew To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-alpha" in the body of the message
