Configuring the SCSI Card 2930U2 with SCSISelect SCSI Device Configuration Note: To configure settings for a SCSI peripheral, you must know its SCSI ID (see Using SCSI Disk Utilities on page 22). s Initiate Sync Negotiation-When set to Yes, initiates synchronous data transfer negotiation (Sync Negotiation) between the peripheral and SCSI card. Leave this setting set to Yes unless any attached SCSI peripheral connected to the SCSI card does not support synchronous negotiation. s Maximum Sync Transfer Rate-Determines the maximum synchronous data transfer rate the SCSI card supports. Use the maximum value of 80.0. If your peripheral is not Ultra SCSI, select a transfer rate of 10.0. s Enable Disconnection-When set to Yes, allows the SCSI peripheral to disconnect from the SCSI bus. Leave the setting at Yes if two or more SCSI peripherals are connected to the SCSI card. If only one SCSI peripheral is connected, changing the setting to No results in slightly better performance. s Initiate Wide Negotiation-When set to Yes, the SCSI card attempts 16-bit data transfer (wide negotiation). When set to No, the SCSI card uses 8-bit data transfer unless the SCSI peripheral requests wide negotiation. Note: Set Initiate Wide Negotiation to No if you are using an 8-bit SCSI peripheral that hangs or exhibits other performance problems with 16-bit data transfer. s Send Start Unit Command-When set to Yes, sends the Start Unit Command to the SCSI peripheral at bootup. s Write Back Cache-When set to Yes or No, enables or disables this feature on the peripheral. If you are not sure your SCSI peripheral supports this feature, leave this setting set to NC (No Change), which will keep the default value on the peripheral. 19
