This 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.
This driver supports:

• Per-unit-basis "feature enforcing" features. They enforce:
  • to turn on "CD-DA readable", "CD-XA readable" and "multisessioning-aware" flags
  • vendor-specific SCSI CD-DA digital reading / CD-XA reading / multisessioning methods
• "WORM-devices as CD-ROM" treatment.
• Per-unit-basis "ignoring drive" feature.
• Enriched /V option output.
• "CD-Extra" (data-multisessioned audio-CD) mounting.
• SCSI-3/MMC-complient CD Capabilities / Mechanical Status Page recognition in default. Salvation for some modern SCSI drives.
• Of course functionally equivalent to
  official OS2CDROM.DMD, including CD-RW / DVD writing and formatting, and USB connection support.

"Some SCSI device drivers report incorrect geometry for media in partitioned removable devices (such as ZIP drives). In addition to some of the media space being unusable, the Logical
Volume Manager (LVM) considers the partitions on the media to be corrupt, and media prepared on non-SCSI attached devices may not be readable. This filter corrects the geometry
reported by the device driver, if required, insuring that all space is reachable and that LVM considers the partitions valid."

This bug only affects users with digital joysticks. The conditions for this bug to happen is when the driver is accessed "many" times possibly creating a lockup while data is getting converted to the analog equivalent form or when the computer gets very heavily loaded. Users with analog-only sticks are not affected.
