R AHA -1540 Family ® Connect any SCSI peripheral to any PC Overview For compatibility and ease of use, the AHA-1540 family of ISA-to-Fast SCSI host adapters is the ideal connection for the widest choice in SCSI peripherals. Rigorously tested with more than 300 systems and peripherals from major manufacturers, these adapters are the recognized standard for SCSI compatibility. Fully Windows® 95 and SCSI Plugand-Play capable, the AHA-1540/1542 host adapters also set the standard for ease of use. Configuration of the adapters is automatic in any Plugand-Play system. PRODUCT HIGHLIGHTS • Tested for compatibility with hundreds of systems and SCSI peripherals • Compatible with all major operating systems • Easy Plug-and-Play installation • Bus master architecture for improved system performance • The industry standard ISA-to-Fast SCSI host adapter Key Benefits Unmatched compatibility The AHA-1540/1542 host adapters connect up to seven SCSI devices to any PC. Designed for computers with standard ISA or EISA expansion slots, they are compatible with virtually any peripheral that complies with the SCSI-2 standard. Plus, they support all major operating systems — Windows 95, Windows NT™, DOS/Windows®, OS/2, UnixWare, and NetWare. Easy Plug-and-Play installation Installation of the AHA-1540/1542 host adapters and SCSI devices is quick and easy. Simply plug in the board, and resources are automatically assigned to ensure compatibility. Used with SCSI Plug-and-Play peripherals and cables, the AHA-1540 family adapters quickly locate all connected SCSI devices, instantly resolve any SCSI resource conflicts, and properly terminate the SCSI bus. With Adaptec EZ-SCSI® software for DOS and Windows, SCSI devices can be installed in minutes following simple menu-driven instructions. Configuration settings can be quickly modified from the keyboard using the Adaptec SCSISelect ® optimization utility. Designed for multitasking AHA-1540/1542 host adapters make multitasking truly efficient. A multithreading, 10 MByte/sec Fast SCSI interface to the ISA bus enables seamless concurrent I/O operations. And bus master DMA takes over I/O processing and frees the CPU for other tasks. Quality and reliability As with all Adaptec products, AHA1540/1542 host adapters have gone through thousands of hours of rigorous functional and environmental tests. Trusted for quality and reliability, Adaptec products are incorporated into the products of virtually all major system and peripheral manufacturers around the world.
