Chapter One Overview This User Guide provides software installation information forthe Adaptec AHA-1740A, 1742A, and the 1744 EISA-to-fast-SCSIbus master host adapters. Cumulatively the cards are referred toas AHA-1740A/1742A/1744 in this guide. The Adaptec adl.exe download utility and the ASW-C174 ...

Installation Software Software required to install the AHA-1740A/1742A/1744, in anEISA system, is provided in the ASW-C174 software package.The files consist of: File Name File Description !adp0000.cfg EISA configuration file for the AHA-1740A/1742A/1744 !adp0001.cfg EISA configuration file for the ...

BIOS Operation Modes The AHA-1740A/1742A/1744 has two modes of operation: stand-ard mode and enhanced mode. The standard mode is softwarecompatible with the AHA-1540 series host adapter drivers. Theenhanced mode uses an advanced, high performance mailbox interface and features full EISA 32-bit addre...

System Caching Description The AHA-1740A/1742A/1744 fully supports operating systemscaching to maximize overall system performance. Having RAMon the host adapter can actually decrease overall system perform-ance while adding cost. Operating systems such as Novell ® Net- Ware, OS/2 ® , UNIX, XENIX, D...

Chapter Two Hardware Installation Unpacking and Inspection The carrier is responsible for damage incurred during shipment.In case of damage, have the carrier note the damage on both thedelivery receipt and the freight bill, then notify your freight com-pany representative so that the necessary insur...

Preparation The configuration options for the AHA-1740A/1742A/1744 can beselected from software. Therefore, jumpers do not need to bechecked before installing the AHA-1740A/1742A/1744 into theEISA system. One exception is the AHA-1742A, since it contains an on-boardfloppy controller. The on-board fl...

SCSI Terminators The SCSI bus must be terminated correctly to ensure proper op-eration. Only the first and last device on the SCSI bus (cable)should have the terminating resistors installed. All other SCSIdevices should have the terminating resistors removed. The fol-lowing figure shows two examples...

Physical Installation in the System The following steps should be followed to install the AHA-1740A/1742A/1744 into the system: 1. Turn OFF the power to the computer system. 2. Remove the system cover according to the directions ofthe computer manufacturer. 3. If only an external SCSI subsystem is u...

Chapter Four Multiple Host Adapter Support The AHA-1740A/1742A/1744 supports more than one host adapter in the system. The maximum number of host adapterssupported depends on the operating mode of the host adapter. Standard Mode An EISA system can support up to a maximum of four AHA-1740A/1742A/1744...

Standard and Enhanced Modes In general, the host adapter SCSI ID does not need to be changedfrom the default of 7. Even if two host adapters are installed inthe same computer, each would have its own SCSI bus (cable),and thus each host adapter would still be set to SCSI ID 7. This value should only ...

Chapter Five Adaptec Download Utility The Adaptec Download utility (ADL) is used to download a differ-ent version of the microcode software to the AHA-1744. Thischapter describes the operation of the program which affects onlythe AHA-1744; the AHA-1740A/1742A do not support microcodereprogramming. A...

Download Firmware After selecting Download Firmware, the next screen displays. Enter the filename of the microcode that you are going to down-load to the host adapter. Enter standard.hex for standard mode and enhanced.hex for enhanced mode. The Mode field must be set to standard to download the stan...

Firmware Information This menu option is used to display information on the installedfirmware. If the AHA-1740A/1742A1744 is operating in the stand-ard mode, only information on the standard mode firmware is dis-played. If the AHA-1740A/1742A/1744 is operating in theenhanced mode, only information o...

Chapter Six Host Adapter BIOS Operation The AHA-1740A/1742A/1744 BIOS operates in two modes: stand-ard and enhanced. The mode of operation is selected with the useof the EISA Configuration utility supplied with you EISA com-puter system. Standard Mode Operation When the adapter BIOS is operating in ...

Enhanced Mode Operation The enhanced mode operation enables the adapter BIOS to iden-tify all installed fixed disks with a valid SCSI ID. All SCSI IDs with the BIOS support option enabled, using theEISA Configuration utility, are scanned. The devices arescanned, starting from SCSI ID 0 and increasin...

Chapter Seven Troubleshooting The AHA-1740A/1742A/1744 executes a self-test diagnosticswhen the system power is turned on or after a Hard Reset. Theself-test diagnostics tests the CPU operation, performs a check-sum test on the EPROM and checks the data transfer paths onthe host adapter. The host sy...

Appendix A Disk Drives Over 1 Gigabyte Extended Translation (Using DOS 5) Adaptec host adapters have always supported the full range ofdisk drive sizes under all major operating systems. As disk driveshave recently grown beyond 1 Gigabyte in formatted capacity,they have run up against the DOS 1024 c...

When to Use Extended Translation With DOS Version 5 Only NetWare 386  and the newer versions of UNIX do not share the 1024 cylinder limit of DOS and do not require extended transla-tion to support large disk drives. OS/2 does not currently supportextended translation. Drives With Mixed Partitions D...

Using Fdisk To install a new disk, or to re-partition an existing disk, use the fdisk DOS utility as you normally would. The cylinder size in- creases to 8 MBytes when you enable extended translation. Thesize of the partition you request must therefore be a multiple of 8 MBytes. If you request a par...
