JJSCDROM.DMD is a modified version of OS/2 CD-ROM / CD-RW / DVDs device manager driver (OS2CDROM.DMD), based on the latest OS/2 DDK on-line source code (DDK_020517).

This driver supports:

* Automatic SCSI-3/MMC-complient drive capability recognition by default, like as ATAPI drive.

* "CD-Extra" (audio-CD w/additional data session) mounting.

* Feature enabling on a per-unit-basis. These features are:

o turn on "CD-DA readable", "CD-XA readable" and "multisessioning-aware" flags

o set vendor-specific SCSI CD-DA digital reading / CD-XA reading / multisessioning / UPC reading methods for non-SCSI-3/MMC-complient drives

* "WORM devices as CD-ROM" treatment for some old WORM-style CD-R drives such as Yamaha CDR10x or any drives filtered by RSJ CD-Writer LOCKCDR.FLT.

* Per-unit-basis "ignore drive" feature.

* Enriched /V option output.

* Additional IOCtl functions that control multisessioning treatment and track 1 negative start LBA fix (Midbar CDS-200 spoiler).

* Of course functionally equivalent to official OS2CDROM.DMD, including CD-RW / DVDs UDF writing and formatting, and USB connection support.
