How do I find out my CD ROM hardware specifics on FreeBSD?

  • 772

I can usually use dmesg soon after bootup to display hardware info that my kernel loads. After my system has been up for a while however, dmesg no longer produces anything of value concerning hardware. How can I find out my hardware specifics, such as what kind of CD ROM drive I have, that is usually found by dmesg?

hardware freebsd dmesg

    For SATA and ATA drives atacontrol info ata# where # is the channel number found by atacontrol list

    For SCSI drives and those passed through with atapicam you can pull info with camcontrol inq dev0 where dev0 is the device name (like cd0, or da0 for hard drives). And camcontrol devlist will list all the devices.

    This lists very detailed information about all hardware including the CD/DVD drive. ( note this is on linux however I suspect there is a freeBSD port/equivalent )
