 на фидо адрес ваш ответ не пришел, поэтому пишу из 
 инета...
 Как я понял из файла README.ATAPI в пакете cdrecord-а
 из *BSD систем ATAPI , т.е. IDE-SCSI adapter emulation 
 поддерживает только NetBSD...исходя из этого можно 
 предположить, что cdrecord в FreeBSD будет работать 
 только со SCSI устройствами, с IDE только burncd
 plz согласитесь или опровергните...
 вот кусочек файла:
 ----------------------------
 People often ask me why do you depend on ATAPI-SCSI 
 emulation, why don't you support generic IDE?
 
 Well first a statement: There is no single IDE burner 
 out!
 Even a CD-ROM cannot be used decently if you use only 
 IDE commands.
 Opening/closing the door, playing audio and similar 
 things cannot be done using IDE commands - you will need 
 SCSI commands to do this. But how do we do this with a 
 drive that uses an IDE interface?
 
 The ATAPI standard describes method of sending SCSI 
 commands over IDE with some small limitations to 
 the "real" SCSI standard.
 For this reason ATAPI-SCSI emulation is the native 
 method of supporting ATAPI devices. Just imagine that 
 IDE is one of many SCSI transport mechanisms.
 
   This are some SCSI transports:
 
 -Parallel SCSI (what most people call SCSI)
 -SCSI over fiber optics
 -SCSI over IEEE 1394 (Fire Wire)
 -SCSI over USB
 -SCSI over IDE (ATAPI)
 As you now see, the use of the naming convention "ATAPI-
 SCSI emulation" is a  little bit misleading. It should 
 rather be called:"IDE-SCSI host adapter emulation"
 
 Some naming explanations:
 
 ATA   Attachment Adapter
 IDE   Integrated Drive Electronics (A Drive that 
 includes ATA)
 ATAPI  ATA Packet Interface

 Which Operating systems support ATAPI
 
 -AIX: Status unknown! Please report your experience...
 -Apple Mac OS X: Supported
 -BeOS (libscg maps ATAPI to SCSI bus # >= 8
 -BSD/OS: Status unknown! Please report your experience...
 -FreeBSD: NO
 -HP-UX: Status unknown! Please report your experience... 
 -Linux (unfortunately not in the default configuration)
 -NetBSD (releases 1.3 and newer)
 -NeXT: Status unknown! Please report your experience...
 -OpenBSD: NO
 -OS/2 (you need to fetch and install ATAPI support first)
 see: 
 http://www.leo.org/pub/comp/os/os2/leo/drivers/dasd/dania
 tapi.zip/
 -OSF-1 / True64 Status unknown! Please report your 
 experience...
 -SCO-OpenServer: Not supported, may change with next 
 release.
 -SCO-UnixWare: NO
 -SGI/IRIX: Status unknown! Please report your 
 experience...
 -Solaris (you may need to use the USCSI transport 
 interface to address ATAPI)
 -VMS: probably not ;-)
 -Win32 using a recent ASPI Layer
