3.3. Which CD-ROM drives are supported by FreeBSD?

Any SCSI drive connected to a supported controller is supported.

The following proprietary CD-ROM interfaces are also supported:

• Mitsumi LU002 (8bit), LU005 (16bit) and FX001D (16bit 2x Speed).
• Sony CDU 31/33A
  
• Sound Blaster Non-SCSI CD-ROM
  
• Matsushita/Panasonic CD-ROM
  
• ATAPI compatible IDE CD-ROMs
  

All non-SCSI cards are known to be extremely slow compared to SCSI drives, and some ATAPI CDROMs may not work.

As of 2.2 the FreeBSD CDROM from Walnut Creek supports booting directly from the CD.
