NOTE: These settings apply to each SCSI ID individually.

Disconnects OK. When set to Yes, the device is notified that it can optionally disconnect from the host adapter. When the drive is ready to continue executing the command, it must re-establish the link through a reconnect cycle. When set to No, disconnects are not allowed. The default is Yes.

If you have more than one device attached to the QLA12160 board, set Disconnects OK to Yes for best performance.

Check Parity. When set to Yes, odd parity is checked and passed to the SCSI FIFO when data is received from the SCSI bus. When set to No, the received SCSI parity is ignored and odd parity is generated for the SCSI FIFO. The default is Yes.

Enable LUNs. When set to Yes, multiple LUNs are supported. When set to No, multiple LUNs are not supported. LUN support is typically required for CD-ROM changers or RAID boxes that use LUNs to map drives. The default is Yes.

Enable PPR. When set to Yes, the QLA12160 board attempts to negotiate for parallel protocol request (PPR) transfers. When set to No, the QLA12160 board does not negotiate for PPR transfers. The default is Yes.

Enable Device. When set to Yes, the system BIOS recognizes the device at this SCSI ID. When set to No, the system BIOS ignores the device at this SCSI ID. The default is Yes.

Negotiate Wide. When set to Yes, the device supports 16-bit, wide (68-pin cable) SCSI data transfers. When set to No, the device supports only 8-bit (50-pin cable) SCSI data transfers. The default is Yes.
