Introduction
The Initio I/OHIGHWAYis a high-performance
PCI bus master FastSCSI host adapter which
provides the interface between the FastSCSI
bus and the PCI local bus. Distiguishing
features include:
Support of 32-bit data transfers across the PCI bus
at speeds up to 133 MBytes per second
The SmartSCSISetup Utility program enables
integration of the host adapters into most platforms
and operating systems
Compliancy with Plug-n-Play applications on
systems using the PCI bus standard
I/OHIGHWAY host adapter supports synchronous
FastSCSI bus transfers at a rate of 10 MBytes
per second. I/OHIGHWAY utilizes full support of
FastSCSI standards defined by SCSI
specifications.

Product Features
PCI Compatibility: The PCI Bus is a 32-bit bus with multiplexed address and data
lines. I/OHIGHWAY is compliant with PCI 2.1 bus protocol, electrical and mechanical
specifications.
Plug and Play: I/OHIGHWAY has an on-board read only memory (ROM) to provide the
necessary configuration mechanisms for installation, configuration, and booting
without user intervention.
133 MBytes per second PCI burst mode: The 32-bit data path for the PCI bus
structure running in a synchronous mode at 33 MHz gives maximum operating speeds
of 133 MBytes/second.
10 MBytes per second data transfer: Up to 10 MBytes/sec synchronous FastSCSI
data transfers for I/OHIGHWAY.
Programmable/Automatic SCSI Termination: Allows the user to choose between
programmable or auto-SCSI termination, eliminating the need to remove system unit
covers each time a change is made in SCSI bus configuration.
Onboard BIOS supports MS-DOS, Windows 3.1x: I/OHIGHWAY has the necessary
software support on-boardallowing you to run disk drive operations for MS-DOS and
Windows 3.1x without any extra drivers.
Windows 95, Windows NT, OS/2, SCO UNIX, UnixWare, Linux and NetWare
Driver Support: I/OHIGHWAY is compatible with all major operating systems.
ISGEIntegrated Scatter/Gather Engine: Initio host adapters have incorporated
advanced hardware functions to provide increased performance in all Scatter/Gather
operations.
No Hardware Jumpers to set: Initio host adapters embed an intelligent software
utility to set configuration options.
Compatible with Hard Disk, CD-ROM, Optical, Tape, Printer, and other SCSI
products: I/OHIGHWAY is a complete FastSCSI implementation. All peripherals are
compliant with SCSI-2 and SCSI-1 and can be used with I/OHIGHWAY.
64-byte FIFO: A 64-byte FIFO buffer is designed into I/OHIGHWAY and is utilized as a
caching buffer to manage PCI to SCSI bus structure timing for data and command
transfer.

Getting Started
Host Adapter and the SCSI Bus
I/OHIGHWAY is a bus mastering host adapter which works with the host computer to
provide control for the SCSI bus. By daisy chaining peripheral devices together, up to
seven devices can be linked with I/OHIGHWAY. The host adapter can be placed in any
standard PCI slot on the bus.
SCSI bus preparation
Each peripheral device attached to the SCSI bus can either be an internal or external
device. Each peripheral has a specific device ID, commonly referred to as a SCSI ID.
Please refer to your peripheral documentation to determine switch or jumper settings for
SCSI IDs. No two devices can have the same ID; the device ID uniquely defines the
device to the SCSI bus.
SCSI bus termination
The SCSI bus structure has a length limitation as well as a requirement for termination at
each end of the SCSI cable. The cable is designed to connect in a daisy chain fashion.
No branching is permitted in the SCSI bus. The first and last physical SCSI device on
the SCSI bus must be terminated (FIGURE 2).

I/OHIGHWAYs SCSI termination can be set to auto-termination or programmable mode
via the SmartSCSI Setup Utility. This feature allows the operator to switch the auto-
termination On or Off. If auto-termination is switched off, the operator can manually
program termination for the host adapter. There are three ways to manually control
terminating the host adapter on the SCSI bus (see TABLE 1).
