ExtenDOS 4 also supports SCSI-3/MMC-compliant and SCSI-2 drives, many SCSI-1
drives, and ATAPI/IDE drives that comply with ATAPI revisions 1.2 and 2.6. The
following shows the features available for each of the supported drives. Note
that later drives from the same manufacturer often use the same command set as
earlier drives; if so, they will be automatically supported by ExtenDOS 4.
