LOCKCDR.FLT

Some CD recorders claim to be CD-ROM drives. As OS2CDROM.DMD allocates all CD-ROM drives at bootup, those recorders cannot be accessed by additional software, including the RSJ CD Writer File System. To correct this behaviour, the filter device driver LOCKCDR.FLT is added to the file CONFIG.SYS; all already known CD recorders will be converted to WORM devices automatically. BASEDEV=LOCKCDR.FLT

Parameters

 * -a: - Filters all commands. Solves problems with the SCSI Bus reset after a session.
 * -i: - "Recorder Name" can be used to specify the device name of the unknown CD recorder.

Example
BASEDEV=LOCKCDR.FLT -i:"IMS CDD2000" In this example, the Philips recorder CDR2000 is added to the built-in list of CD recorders. During bootup, the OS/2-internal device tables are modified such that the CD recorder is treated as a WORM device instead of a CD-ROM.

The name of all connected CD-ROM devices as well as whether they have been converted to WORM devices is printed to the screen while the system is booting.


 * Note: It is not necessary to specify the complete device name. In the example above, specifying -i:"IMS" would do the same job. However, the more complete the device names are specified, the less likely it is that a CDROM drive is converted to a WORM device accidentally.
