ExtenDOS 4 runs on almost all TOS-based system, including:
 | original Atari systems, including the ST, STe, Mega, MegaSTe, TT030, and Falcon030 |
| Atari-compatibles, including the Hades040 and Hades060 |
| many upgrade boards for Atari systems, including the Afterburner, CenTurbo2, and CT60 |
| most systems that contain a SCSIDRV interface to SCSI or ATAPI CD devices, including MagicPC, MagicMac, and systems that support SCSIDRV via a third-party driver such as HDDRIVER. Please note that you may encounter problems when running under MagicMac on 68040-equipped systems unless the 68040 cache is disabled. |
For the latest information on system compatibility, please contact Anodyne Software.
ExtenDOS 4 supports the following devices:
| a SCSI CD or DVD device connected to the SCSI port of a TT030 / Falcon030 / Hades060, or to a SCSI port that is accessible via SCSIDRV |
| a SCSI CD or DVD device connected via a suitable host adapter (see below) to the ACSI port of an ST/STe/Mega/MegaSTe/TT030, or to an ACSI port that is accessible via SCSIDRV |
| an ATAPI CD or DVD device connected to an IDE port that is accessible via SCSIDRV |
Note that it is also possible to connect an ATAPI device to a SCSI port with a suitable converter.
SCSI drives must be connected to the ACSI port of an Atari system via a host adapter, which performs the protocol conversion between ACSI and SCSI. If you wish to connect a device that requires SCSI arbitration (such as most CD recorders), the host adapter must provide this function. At this time, the only host adapters that support SCSI arbitration are the Link96/Link97 host adapters by WB Systemtechnik.
In order to support all other ExtenDOS 4 facilities, including playing audio CDs, reading photoCDs, and direct audio CD recording, the host adapter must be an ICD AdSCSI+/Link/Link2 or WB Systemtechnik Link96/Link97 or equivalent host adapter. These adapters implement the ICD extended SCSI command support, which allows the full range of SCSI commands to be sent to the drive.
Most other host adapters (including the original Atari host adapter, the Supra, the BMS, and certain early ICD adapters) are not capable of transmitting the commands necessary to support audio CD and photoCD.
If you're not sure whether your host adapter is compatible, please contact Anodyne Software.
