Integrated Controllers
The system board has three integrated controllers. Each controller can be disabled if
needed using the BIOS Setup program. For more information, see Chapter 3, “BIOS
Setup”.
SCSI Controller
The system board includes an integrated LSI 53C1010 SCSI controller. The controller
provides the system with a dual-channel Ultra3 SCSI bus.
Channel A connects to an external SCSI port and (on some systems) to internal SCSI
devices. Channel B connects (on some systems) to internal SCSI devices. Both channels
use 68-pin SCSI connectors located on the system board.
Warning:
For continued protection against fire and energy hazards, do not connect
an external SCSI port to SCSI Channel B. Connect an external SCSI port only to SCSI
Channel A.
Controller features include:
•
Low-Voltage Differential (LVD) bus
•
2 16-bit 80 MHz channels
•
160 MB/sec transfer rate per channel for Ultra3 devices
•
Ultra2 and Ultra3 devices connected to the controller operate at their respective
transfer rates
•
PCI bus interface
•
Advanced Configuration and Power Interface (ACPI) support
You may need to use the SCSI Configuration Utility to configure the operation of SCSI
peripherals connected to the controller. This utility lets you configure SCSI controllers,
perform a low-level format on a SCSI hard disk drive, select boot order, and verify media.
To run the SCSI Configuration Utility, press
CTRL
+
C
when prompted during system boot.
See SCSI Configuration Utility Help for more information on using the utility.
