SCSI Device Configuration Menu This menu lets you configure parameters for each SCSI device on the SCSI bus. To configure a specific SCSI device, you need to know which SCSI ID it uses.

Press [ENTER] to display a menu with a selection of values. • Initiate Sync Negotiation Some older SCSI-1 devices do not support synchronous negotiation. Set Initiate Sync Negotiation to No for these devices. • Maximum Sync Transfer Rate Certain older SCSI-1 devices do not support Fast SCSI data transfer rates (typically 10.0, 8.0, and 6.7). Select a Maximum Sync Transfer Rate of 5.0 for these devices. • Enable Disconnection To optimize SCSI bus performance, Enable Disconnection should be set to Yes when two or more SCSI devices are connected to the host adapter. Set Enable Disconnection to No to achieve slightly better performance when only one SCSI device is connected to the SCSI bus. • Send Start Unit Command This option is not supported by some SCSI devices. Some SCSI devices require a jumper to be changed before they can respond to this command. When set to Yes this option reduces the load on your computer's power supply by allowing the interface to power-up SCSI devices one-at-a-time when you start your computer. When set to No each SCSI device powers up at the same time. • Include in BIOS Scan When this option is set to Yes the interface BIOS supports devices attached to the SCSI bus without the need for device driver software. This option is valid only if the interface BIOS is enabled.
