>Description:
I am unable to burn either dvd's or cd's with a sata atapi drive(ASUS DRW-2014L1T/1.02) when AHCI is enabled in BIOS.  Normally, I have atapicam and ahci in /boot/loader.conf, however disabling either one or both doesn't change the outcome.  After disabling AHCI in BIOS, I am now able to burn optical media again.

>How-To-Repeat:
Attempt to burn CD/DVD using burncd, cdrecord, or growisofs with their appropriate cli options and /dev while AHCI is enabled in BIOS.
>Fix:
Disable AHCI in BIOS
