You can configure the CD/DVD recorder module of GEAR with several parameters. You can specify configuration options for the SCSI driver, and also options for the recording process itself. You can change these parameters manually in the .gearrc configuration file, or you can get and set these parameters with the commands GETCDRDEFAULTS, SETCDRDEFAULTS, GETCDRPARMS and SETCDRPARMS. Please refer to the GEAR Command Reference chapter for more information on these commands, and which parameters you can change. Below, an additional explanation is given about what these parameters actually mean and do:

CDRInterface Identifies the SCSI driver to use for interfacing with CD/DVD recorder devices. The default value is 2 on most platforms. Valid values are: 1) Tracer Technologies SCSI device driver (special file at 'SCSIPath1'). 2) GEAR/Standard SCSI device driver (special file at 'SCSIPath2'). 3) Caldera SCSI device driver (special file at 'SCSIPath3'). 4) GEAR IDE driver, for Solaris Sparc only (special file at 'SCSIPath4'). 5) sgen driver, for Solaris Sparc only (special file at 'SCSIPath5').

SCSIPath1xx Identifies a template for the device-special file used for accessing a CD/DVD recorder device, when the Tracer SCSI driver (gd driver) is used. This value must be correct, otherwise the software cannot locate the device. The default value depends on your Unix system, xx identifies the actual Unix platform.

SCSIPath2xx Identifies a template for the device-special file used for accessing a CD/DVD recorder device, when the standard platform SCSI-driver is used. This value must be correct, otherwise the software cannot locate the device. The default value depends on your Unix system, xx identifies the actual Unix platform.

SCSIPath3xx Identifies a template for the device-special file used for accessing a CD/DVD recorder device, when the Caldera SCSI-driver is used. This value must be correct, otherwise the software cannot locate the device. The default value depends on your Unix system, xx identifies the actual Unix platform.

SCSIPath4xx Identifies a template for the device-special file used for accessing a CD/DVD recorder device, when the GEAR IDE driver for Solaris Sparc is used. This value must be correct, otherwise the software cannot locate the device.

SCSIPath5xx Identifies a template for the device-special file used for accessing a CD/DVD recorder device, when the sgen driver for Solaris Sparc is used. This value must be correct, otherwise the software cannot locate the device.

TargetID Identifies the target ID of CD/DVD recorder device to use. If only one device is connected, GEAR finds the unit automatically, regardless of its ID. If more than device is connected, GEAR will look for the one that matches TargetID, otherwise the unit with the highest ID is used. Valid values are 0 to 15. On some Unix platforms the ID is equivalent to the SCSI ID of the device, but on some Unix platforms the ID might only be a logical number assigned by the kernel that has no relation with the actual SCSI ID. GEAR combines the TargetID with the SCSIPath template to construct the name of device special file to open for the device.

SCSIBusID Identifies the SCSI Bus ID of the CD/DVD recorder device to use. Valid values are 0 to 7. Not all Unix systems actually use the bus ID. On some Unix platforms GEAR combines both the SCSIBusID and the TargetID with the SCSIPath template to construct the name of device special file to open for the device.

SCSIBufferSize Identifies the SCSI buffer size in bytes allocated by GEAR for transfers to the SCSI Driver and the SCSI device. The minimum value is 32768 (32KB). The default value is 65536 (64K)

ImageReadBufferSize Identifies the buffer size in bytes allocated by GEAR for file IO transfers, when the Recorder module is reading data from a GEAR image and transfers data to the CD/DVD recorder device, This occurs during the writing of a disc (WRITECD command) . The default value is 262144, and the maximum value is 1048576 (1MB).

ImageWriteBufferSize Identifies the buffer size in bytes allocated by GEAR for file IO transfers, when the Recorder module is reading data from the CD/DVD recorder device and outputs to a file. This occurs during the extraction of tracks from a disc with the READCD and READTRACK command. The default value is 262144, and the maximum value is 1048576 (1MB).

WriteMethodCD Determines the write method to use when writing CD-R(W) discs. Possible values are: 1.) Disc at once recording (write lead in->tracks->lead out: no link areas). 2.) Track at once recording (first write tracks, then fixate). WriteMethodDVD Determines the write method to use when writing DVD-R(W) discs (GEAR PRO DVD only).
