The table on the opposite page lists the commands in the SCSI-2 command set and their corresponding

Applied Model
Applied Model has three values. Each model code corresponds to particular drive models.
I : product models DRM-604X; DRM-1804X; and DR-D504X
II : product model DRM-602X
III : product models DRM-624X; DR-U124X; DR-UA124X; DR-A10X; DR-U10X;
DR-A12X; DR-411; DR-U12X; DR-433; DR-A24X; DR-511; DR-U24X; and
DR-533
Each command is either supported by a drive, indicated by “yes”, not supported by a drive, “---“,
or is supported but with restrictions and/or conditions, “N” where N is a numeric value 1-7.
yes : is supported by all drives corresponding to this Applied Model code.
--- : is not supported by any of the drives corresponding to this Applied Model code.
1 : is not supported by DRM-1804X.
2 : does not support the media type code 4h, 8h, 70h, 71h and 72h. There is limited
action in the CD-ROM Audio Controller Parameter Page (0Eh).
