On PCs all slots share the same 4 physical irqs and the lines are hardwired on the board in alternating order to each slot. If you want cards not to share irqs you have to swap slots until you get what you want - you can't enforce it with software. -- 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-hackers" in the body of the message
