Ok. There are two things that would be useful: 1. Merging the multiple LBA to C/H/S calculations (aic7xxx, umass, ...) to one CAM convenience routine. 2. Adding a MI way to call an MD routine that will get the disk's physical geometry. I don't know much about the best way to do this. -Nate To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-current" in the body of the message
