Using SCSISelect Settings Using SCSISelect Settings To select an option, use the ↑ and ↓ keys to move the cursor to the option, then press Enter. In some cases, selecting an option displays another menu. You can return to the previous menu at any time by pressing Esc. To restore the original SCSISelect default values, press F6 from the main SCSISelect screen. SCSI Bus Interface Definitions I Host Adapter SCSI ID-Sets the SCSI ID for the SCSI card. The SCSI Card 2906 is set at ID 7, which gives it the highest priority on the SCSI bus. You should not change this setting. I SCSI Parity Checking-When set to Enabled, verifies the accuracy of data transfer on the SCSI bus. Leave this setting enabled unless any SCSI device connected to the SCSI card does not support SCSI parity. If one SCSI device does not support SCSI parity, set parity on the 2906 to Disabled. I Host Adapter SCSI Termination-Determines the termination setting for the SCSI card. The default setting is Automatic, which determines termination as follows: I If a cable is only connected to the SCSI card's internal or external SCSI connector, the terminators are enabled if the 2906 termination is set for automatic. (The SCSI card is at the end of the SCSI bus.) I If a cable is connected to the SCSI card's internal and external SCSI connector, the terminators are disabled. (The SCSI card lies between the ends of the SCSI bus.) You can also disable the terminators by setting Host Adapter Termination to Disable. You should leave this setting at its default (Automatic). Note: The option is for terminating the SCSI card, not for terminating devices. Be sure that both ends of the SCSI bus are terminated. Refer to the Adaptec SCSI Card 2906 Installation Guide for details. 35
