Preface - Adaptec AHA-1740A Technical Reference Manual

Preface

This Technical Reference Manual provides technical information for Adaptec's
AHA-1740A/1742A/1744 EISA-to-Fast SCSI Host Adapters. It is prepared for cus-
tomer technical personnel requiring detailed information on the operation of the
board at a register and command protocol level. Documentation of board schematics,
integrated circuits, microcode and BIOS routines is not provided.
Programmers writing device drivers for specific perpherals are strongly advised to
use the Advanced SCSI Programming Interface (ASPI) specification appropriate to
the operating system chosen. This will allow flexibility across all boards complying
with ASPI Manager modules and prevent obsolescence. Please contact Adaptec
Corporate Communications for copies of ASPI specifications. Software managers are
documented and sold separately.
Every effort has been made to ensure the technical accuracy of this reference man-
ual. If you believe that inaccuracies exist, please communicate this information in
writing to your local field applications support personnel or directly to the product
manager.
