Chapter 1. Overview
The PCI SCSI-2 Fast/Wide Single-Ended Adapter enables you to use internal and
external small system unit system interface (SCSI) devices with system units
containing a Peripheral Component Interconnect (PCI) bus. The adapter conforms to
the American National Standards Institute (ANSI) SCSI-2 standard and the PCI local
specification, revision 2.0.
The PCI SCSI-2 Fast/Wide Single-Ended Adapter supports fast and wide SCSI
synchronous data rates up to 10 MHz. Wide (16-bit) SCSI supports a maximum
transfer rate of 20 MB (20,000,000 bytes) per second. Narrow (8-bit) SCSI supports
a maximum transfer rate of 10 MB per second.
The PCI SCSI-2 Fast/Wide Single-Ended Adapter allows the connection of internal
and external SCSI devices.
