I have a machine with some SATA disks connected to an ICH9 controller. The BIOS has no options to enable AHCI support on the controller (not that I know for sure that it even has AHCI support). Once a disk on the controller is removed, using the old ata(4) driver, no new disks are detected using atacontrol's "reinit" or "detach" and the machine must be rebooted for the new disk to be seen. I'm wondering whether this has a chance of working with the new ATA_CAM code. If so, I'll give it a whirl and report back. Thank you. -Boris
