HP Kayak XU 03xx PC Workstation Configuring a SCSI Accessory • Maximum Sync Transfer Rate If the SCSI device is an UltraWide SCSI device, you can use the maximum value of 40.0 MB per second. For Ultra narrow SCSI or Wide SCSI devices you can select a maximum transfer rate of 20.0 MB per second. Certain older SCSI-1 devices do not support UltraWide SCSI (up to 40 MB per second) or Ultra narrow SCSI or Wide SCSI data transfer rates (up to 20 MB per second). Select a Maximum Sync Transfer Rate of 10.0 MB per second for these devices. • Enable Disconnection To optimize SCSI bus performance, Enable Disconnection should be set to Yes. • Initiate Wide Negotiation This option determines whether the SCSI channel attempts 16-bit data transfer instead of 8-bit data transfer. • Send Start Unit 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. 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. • BIOS Multiple LUN Support More advanced SCSI devices can have several logical units (LUN). This option determines whether booting a SCSI device that has multiple LUNs is supported. Set this option to Yes if your boot device has multiple LUNs. It is set to no by default. • Include in BIOS Scan This setting, when set to Yes, allows the SCSI device to be controlled by the host adapter with this SCSI ID. When set to No, the adapter does not control the SCSI device. 6 English
