X-BeenThere: freebsd-questions@freebsd.org X-Mailman-Version: 2.1.5 Precedence: list List-Id: User questions List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , X-List-Received-Date: Wed, 23 Nov 2011 11:43:40 -0000 What is the role of "options atapicam" and "device ATA_CAM" in kernel config file? Are they redundant? Kernel will build with both these options, but will it make things go awry? Is ATA_CAM deprecated? I am trying to burn a CD (or DVD) on a SATA DVD-RW drive, but cdrtools don't work. Also, how do I build and install a kernel to some name other than /boot/kernel, and not build all modules in duplicate? I might want to try kernels with some differences in options, but with the same modules. NetBSD and Linux make it easy to choose a non-default name for the kernel, so I can have multiple kernels and choose one at boot. In Linux, beginning with kernels 2.6.*, cdrtools work without the ATA-SCSI dance. Tom
