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.
