Configuring the SCSI Card 2930CU with SCSISelect 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, change this setting to Disabled. I Host Adapter SCSI Termination-Determines the termination setting for the SCSI card. The default setting is Automatic, which determines termination this way: I If a cable is connected to the SCSI card's internal or external SCSI connector, the terminators are enabled. (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. Adaptec recommends that you leave this setting at its default (Automatic). Boot Device Options I Boot SCSI ID-Specifies the SCSI ID of your boot drive. I Boot LUN Number-Specifies which LUN to boot from on your boot drive. BIOS Multiple LUN Support must be enabled (see page B-5). SCSI Device Configuration Options Note: To configure settings for a SCSI device, you must know its SCSI ID (see Using SCSI Disk Utilities on page B-7). I Initiate Sync Negotiation-When set to Enabled, initiates synchronous data transfer negotiation (Sync Negotiation) between the device and SCSI card. Leave this setting enabled unless any SCSI device connected to the SCSI card does not support synchronous negotiation. I Maximum Burst Rate-Determines the maximum synchronous data transfer rate the SCSI card supports. If you have an Ultra B-4
