FCC Compliance Statement
This equipment has been tested and found t o comply with the limits for a Class B digital device, pursuant to Part 15 of the FCC rules. These limits are designed to provide reasonable protection against harmful interference in residential installations. This equipment generates, uses, and can radiate radio frequency energy, and if not installed and used in accordance with the instructions, may cause harmful interference to r adi o communicati ons. However, there is no guarantee that interference will not occur in a part icular installati on .
If this equipment does cause interference to radio or television equipment reception, which can be determined by turning the equipment off and on, the user is encouraged to try to correct the inter­ference by one or more of the following measures:
• Reorient or relocate the receiving antenna
• Move the equipment away from the receiver
• Plug the equipment into an outlet on a circuit different from that to which the receiver is powered
• If necessary, the user should consult the dealer or an experienced radio/television technician for additional suggest ions
CAUTION: Only equipment certified to comply with Class B (computer input/ou tp ut devices, terminals, printers, etc.) should be attached to this equipment, and must have shielded interface cables.
Finally , any changes or modifications to the equipment by the user not expressly approved by the grantee or manufacturer could void the user ’s authority to operate such equipment.
Each host adapter is equipped with an FCC compliance label which shows only the FCC identifi­cation number. The full text of the associated label follows:
This device comp lies with part 15 of the FC C rules. Operat ion is subject to the followi ng two conditions: (1) this devi ce may not cause harmful interference and (2) this device must accept any interference received, inclu ding interference that may cause undesired operation.

Advisories
Advisories are quick notes that stress an important point or warn of a potential hazard to your system, your data and/or your pers onal sa fety. This manual uses three kinds of advisories:
Note: Text set off in this way presents remind -
ers, tips or suggestions that may make it eas­ier for you to install, configure and use your host adapter.
Caution: Failure to observe this kind of advi-
sory could result in loss of data or damage to your system and installed devices
WARNING: Failure to observ e this kind of
advisory could result in personal injury. Use caution when hand ling any electrical equi pment. Advisories in this man ual can only cov er the proce-
dures contained here, and not all situations may have been addressed. Adaptec does not claim to have included every condition or situation that might require a Caution or Warning. You must refer to the documentatio n for your comput er and peripher al devices when you are installing equipment or chang­ing its configuration.

Introduction
General Product Information
The AHA-1510A/20A Series consists of three host adapter models:
■ AHA-1510A: ISA-to-SCSI host adapter
■ AHA-1520A: ISA-to-SCSI host adapter with onboard BIOS
■ AHA-1522A: ISA-to-SCSI host adapter with onboard BIOS
and floppy drive controller
Adaptec’s AHA-1510A/20A Series host adapters break the price/performanc e barrier w ith multitas king ISA-to-SCSI I/O per­formance. These host adapters greatly enhance the I/O performance of ISA-bus and EISA-bus microcomputers with the much faster SCSI data transfer rates. AHA- 1 510A / 20A Seri es host adapt ers provid e superior data I/O performanc e at an affordable price.
AHA-1510A/20A Series host adapters excel in single user environ­ments (i.e., stand- alone com put ers or netwo rk nodes ) by utilizing the CPU’s untapped power to improve system I/O performance. AHA-1510A/20A Series host adapters support up to eight simulta ­neous I/O tasks and can connec t up to 56 devices (7 SCSI ta rgets with 8 logical units per target).
AHA-1510A/20A Series host adapters are fully compatible with most SCSI devices and ISA-bus/EISA-bus computers . They fully support SCSI-1 and SCSI-2.
AHA-1510A/20A Series host adapters give you access to Adaptec’s ASPI (Advanced SCSI Program min g Interface ) family of software. This family includes devi ce drivers that work with tape, disk, CD-ROM, WORM , and DAT devices and also with operatin g sys ­tems such as DOS, OS/2, UNIX, and Net Ware. The ASPI software communicat es with the operating sys tem m an agers through the common ASPI platform.
