Copy VCD under FreeBSD

First, scsi device support should be enabled by adding atapicam_load="YES" to /boot/loader.conf, then do a cdrdao scanbus to get the device number, followed by cdrdao read-cd --device 1,0,0 --driver generic-mmc -v 3 v to copy the vcd file to data.bin. A lot of options are available in the manual page of cdrdao, just read it to choose the relevant options. The options I have used is from http://www.k4ml.com/node/76, with a device number modification, which works for me.
