Since you do not have any hard disks attached to your second IDE channel, I suggest to comment the last two lines out and compile the kernel again. > options ATAPI > options ATAPI_STATIC > device wcd0 > The drive is detected on boot up too: > > /kernel: wdc1: unit 1 (atapi): <FX801S/X01>, removable, intr, dma, iordis I don't think the system has detected the CDROM. Perhaps it misidentifies the CDROM as a removable hard disk. So, as I suggested above, comment those two lines and compile the kernel again.
