Using the SCSI Feature

The system board features a single-chip Ultra Fast and Wide SCSI-2 host adapter that adds SCSI I/O capability to the system.

The chipset consists of all the components found on the state-of-the-art SCSI host adapters such as the following:

∙Onboard microcontroller

∙Bus master interface controller

∙SCSI controller

The chipset allows transfers at a full 40 MB/second burst transfer rate.

Note: Ultra SCSI speed is not supported on external SCSI devices because of the Ultra SCSI stringent requirements in total SCSI bus length. To use an external SCSI devices, use the SCSISelect utility to disable support for Ultra SCSI speed. See the heading, “Configuring the SCSI Adapters and Drives” in the “Sample Standard Configuration” section of Appendix C.

To use the feature, install any SCSI device in your system and connect it to the SCSI interface on the system board. (See Figure 2-7 in Chapter 2 of this manual for the location.) Then, enter the BIOS Setup utility to set the PCI slot parameters. See Chapter 4, “Using the BIOS Setup Utility”, for details in setting the parameters. Refer to the SCSI manual for more information on using SCSI.
