I do have all this in the kernel, see below. Still if I don't have device ata, I get no cd: # ls /dev acpi console kbd0 stdin ttyve ad4 consolectl klog stdout ttyvf ad4s1 ctty kmem sysmouse ugen0.1 ad4s1a devctl log ttyv0 ugen0.2 ad4s1b devstat mdctl ttyv1 ugen1.1 ada0 dumpdev mem ttyv2 ugen2.1 ada0s1 fd midistat ttyv3 ugen3.1 ada0s1a fido mixer0 ttyv4 ugen4.1 ada0s1b geom.ctl null ttyv5 ugen5.1 apm io pass0 ttyv6 urandom apmctl ipauth pccard0.cis ttyv7 usb atkbd0 ipl pci ttyv8 usbctl audit iplookup psm0 ttyv9 xpt0 bpf ipnat ptmx ttyva zero bpf0 ipscan random ttyvb bpsm0 ipstate sndstat ttyvc cam ipsync stderr ttyvd # Here's the kernel config file: cpu HAMMER ident BUZI makeoptions DEBUG=-g # Build kernel with gdb(1) debug symbols makeoptions MODULES_OVERRIDE= options ATA_CAM # Handle legacy controllers with CAM options ATA_STATIC_ID # Static device numbering options AUDIT # Security event auditing options CAPABILITIES # Capsicum capabilities options CAPABILITY_MODE # Capsicum capability mode options CD9660 # ISO 9660 Filesystem options COMPAT_FREEBSD32 # Compatible with i386 binaries options COMPAT_FREEBSD7 # Compatible with FreeBSD7 options COMPAT_LINUX32 options DDB # Support DDB. options DEADLKRES # Enable the deadlock resolver options FFS # Berkeley Fast Filesystem options GDB # Support remote GDB. options GEOM_LABEL # Provides labelization options GEOM_PART_GPT # GUID Partition Tables. options HWPMC_HOOKS # Necessary kernel hooks for hwpmc(4) options IEEE80211_AMPDU_AGE # age frames in AMPDU reorder q's options IEEE80211_DEBUG # enable debug msgs options IEEE80211_SUPPORT_MESH # enable 802.11s draft support options INCLUDE_CONFIG_FILE # Include this file in kernel options INET # InterNETworking options INET6 # IPv6 communications protocols options INVARIANTS # Enable calls of extra sanity checking options INVARIANT_SUPPORT # Extra sanity checks of internal structures, required by INVARIANTS options IPFILTER options IPFILTER_DEFAULT_BLOCK options IPFILTER_LOG options KBD_INSTALL_CDEV # install a CDEV entry in /dev options KDB # Enable kernel debugger support.
