I was editing the GENERIC kernel It's the amount of time the SCSI subsystem will wait for devices to "settle" before trying to probe everyone. If you don't have any ill-behaved tape drives or other SCSI devices with long setup times, you can take it out. > the LINT configuration and it doesn't even mention it.

You won't affect performance at all, really, you'll just decrease the amount of time it takes you to boot the system. Once you're up, it has no further effect. -- - Jordan Hubbard FreeBSD core team / Walnut Creek CDROM.
