hi. i have a production system with an ncr0 SCSI controller that's pretty weak. I would like to add an adaptec, which comes in as ahc0. The problem is that when I add the ahc0 in to the system, it comes up ahead of the ncr0, and so the system disk is labeled da1, and .. well .. there are ways to deal with this .. i thought, based on the admonition about ISA NIC probes, that order in the kernel conf file might predicate probe order, but even in GENERIC, ncr0 comes ahead of ahc0 .. so .. no dice. 1) Can I modify the order in which these devices are detected so that the ncr0 comes out first, making my life simpler? How? 2) Failing that, how the freak do I MAKEDEV the disk slices so I can mount the system slices on da1s1 instead of da0s1? Or will the OS dtrt when it sees that I've MAKDEVed da1s1 and create the slices automagically? I've managed to boot single-user by modifying boot device at the kernel prompt ... 3) TIA. :) Thanks, -danny To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-hackers" in the body of the message
