The BIOS-resident SCSISelect configuration utility eliminates the need to handle jumpers
or terminators while adding peripherals. All configuration and terminator settings are
controlled via the keyboard (see "SCSISelect Utility" in Section 2). The SCSI adapter
board feature the following:
n
PCI to UltraSCSI host adapter with SCSISelect, utilizing the PCI local-bus to
support up to fifteen SCSI devices
n
Bus master DMA interface protocol
n
32-bit bus width
n
Up to 133 MB/second data transfer rate
n
Fast and wide 20 MB/second SCSI synchronous data rate
n
6 MB/second SCSI asynchronous data rate
n
SCSI-2 and SCSI-3 device protocol
n
Advanced SCSI Programming Interface (ASPI) compliant, multi-threaded I/O
scatter/gather, tagged queuing, disconnected, synchronous and asynchronous fast
and wide.
n
Extended translation scheme supports up to eight GB per disk
n
Drivers may be single-ended, active, or programmable via SCSI configuration
utility.
DISKETTE DRIVE
Up to two diskette drives are supported in the system. The installed 3 1/2-inch diskette
drive is connected by a single ribbon cable with two drive connectors. The diskette drive
cable plugs directly into the system board. Typically, there are no switches or jumpers that
need to be set, both diskette drives are terminated and the cable determines drive A and B.
Connector locations are given in Appendix A.
HARD DISK DRIVE
Up to four IDE hard drives are supported in the system (non-SCSI configurations). In the
SCSI configuration, up to 15 SCSI devices (disk drives, CD-ROM drives, scanners, tape
backups) are supported by the Ultra Wide SCSI adapter board. Two SCSI devices can be
installed internally in the system chassis.
IDE Hard Drives
The system board has two IDE/PCI interface connectors (primary and secondary) for
connecting IDE storage devices such as hard disk drives. Each connector supports up to
two IDE devices. Connector locations are given in Appendix A.
