These files come standard with your AHA-2740 Series host adapter. The Adaptec AHA-2740 Series or AHA-2840 Series User's Guide. Performing a Windows NT Installation ==================================== Follow these instructions if you are installing an Adaptec AHA-2740 Series or AHA-2840 Series host adapter and Windows NT at the same time. You may install Windows NT from a floppy drive or from a CD-ROM drive; whichever you choose, make sure the hardware installation is completed prior to following these steps. Note: Follow these procedures exactly to install the new driver. The install program tries to access the old driver on other Windows NT floppy disks or from the CD during installation. 1) If you choose to install Windows NT from a floppy drive, locate the Windows NT Disk 1 for Floppy Installation. Make a backup copy of this diskette. If you are installing from a CD-ROM drive, locate the Windows NT Setup Disk for CD-ROM Installation. Make a backup copy of this diskette. 2) Delete the file arrow.sys from the backup diskette you just created. 3) Put this disk into drive A (not drive B) and turn on your computer. 4) When prompted, select Custom setup. Note: If you choose Express setup, the installation process is unable to detect your Adaptec host adapter and the installation fails. 5) Windows NT setup cannot recognize the adapter and displays none. Press S to configure additional SCSI adapters. 6) From the list of additional SCSI adapters, select Other (Requires disk provided by a hardware manufacturer). 7) Insert the Adaptec 7700 Family Manager Set Diskette for NetWare, OS/2, and Windows NT into drive A and press Enter. 8) The screen displays the adapter similar to Adaptec 2740 / aic777x. Press Enter. 9) If you want to add other host adapters, do so at this time by following steps 6 through 8 for each additional adapter. 10) Press Enter to continue with the Windows NT operating system setup. Follow the instructions given onscreen and in the Windows NT installation documentation. Updating Windows NT with the New Driver ======================================= This section explains how to make the following hardware changes to your computer without reinstalling Windows NT: Add an Adaptec host adapter that uses the same driver as one already installed on your computer, and add an Adaptec host adapter that uses a different driver. Swap an Adaptec host adapter for one that uses a different driver. Remove an Adaptec host adapter. Note: These operations are similar but have important distinctions, as described in the following sections. Read the instructions carefully before you change your computer configuration. Adding a Host Adapter ===================== This section details installing a host adapter to a computer. If you are adding an Adaptec host adapter to a computer that already has an installed host adapter of the same family (for example, if you have added an AHA-2740 to a computer that already has an installed AHA-2740), perform steps 1 through 5 only. If you are adding a host adapter that uses a different driver, you must perform all the steps in this section to ensure that the device driver for the new host adapter is both installed on your system disk and is enabled. The steps are as follows: 1) Shut down Windows NT. 2) Power OFF your computer and physically install the new host adapter in an available slot. Refer to the host adapter hardware documentation for installation. WARNING: Always refer to your computer’s documentation for instructions on opening the computer cover and adding boards. 3) Verify that there are no system resource conflicts (e.g. interrupt request level or DMA channel) between the new host adapter and other hardware installed in the computer. Refer to the host adapter hardware documentation for instructions. 4) Restart the computer and, if necessary, run the EISA configuration utility (for EISA boards) before Windows NT reboots. 5) Boot Windows NT. If you have just added an Adaptec host adapter to a computer that already has an installed host adapter of the same family (for example, if you have added an AHA-2740 to a computer that already has an installed AHA-2740), your installation is complete. 6) Select and start the Windows NT Setup program. (Its icon is usually found in the Main program group.) There is a brief pause while Windows NT Setup scans your hardware configuration. 7) Select the Options pull-down menu and then select Add/Remove SCSI Adapters. The SCSI Adapter Setup program displays a list of host adapters currently installed. 8) Click on the Add button to add another host adapter type to the list. Expand the list and select the type of host adapter to be added. For this example, we assume you are adding an AHA-2740 to a computer that already has an AHA-1540C. 9) Click on the Install button. At this point, Windows NT Setup checks to see if the specified driver (in this example, arrow.sys) has already been copied to the system disk. If this type of host adapter was previously installed, the following message appears: The driver(s) for this SCSI adapter are already on the system 10) Click on Current if you want to use the existing device driver or click on New if you want to replace it. If you select Current, skip to step 12. If the device driver has never been installed, this message appears: Please enter the full path to the Windows NT SCSI Adapter files. 11) Change the path to the directory with the desired device driver, then click on Continue. The device driver is copied to your system disk and the Windows NT configuration is updated so that the new device driver loads when Windows NT reboots. 12) When the installation is complete, Windows NT Setup again displays a list of currently installed host adapter types. Verify that the new host adapter appears on the list. 13) Add other types of host adapters if necessary (see steps 8 through 12 above), or click on Close to exit the SCSI adapters portion of Windows NT Setup and then close the program. 14) When you see this message, click on OK to exit: The changes you have made will not take effect until the computer is restarted. If this message does not appear, no changes have been made to the Windows NT system configuration. 15) Restart your computer and Windows NT. It is possible that some drive letter assignments may change from the previous configuration. Swapping a Host Adapter ======================= Swapping one type of host adapter for another is similar to the procedure for adding a host adapter. The important distinction is that you make all software configuration changes while Windows NT is running. 1) Install the driver for the new host adapter by following steps 6 through 15 in the section Adding a Host Adapter above. It is not essential to remove the device driver for the host adapter you are replacing. Windows NT dynamically detects the absence or presence of host adapter hardware, and no problems should arise if you leave the existing device driver installed. You may remove the device driver later, after you have successfully rebooted Windows NT. 2) Once the new device driver is installed, shut down Windows NT and replace the existing host adapter, as described in steps 1 through 5 of Adding a Host Adapter above. 3) Restart your computer and Windows NT. It is possible that some drive letter assignments may change from the previous configuration. Caution: If the host adapter you are swapping controls the computer boot device, you must follow the additional steps in the next section in order for Windows NT to work correctly. Swapping the Boot Host Adapter ============================== If the host adapter you are changing controls the system disk from which your Windows NT system loads, you must update the device driver in two locations (because Windows NT boots in a two-stage process): the Windows NT device driver directory (i.e. \winnt\system32\drivers) and c:\ntbootdd.sys. In the first stage of booting, no software configuration is available and Windows NT loads the device driver to control the computer boot disk from the file c:\ntbootdd.sys. Therefore, when you perform the steps described above to swap a host adapter you must also explicitly copy the arrow.sys device driver to c:\ntbootdd.sys (meaning arrow.sys is copied over and renamed as c:\ntbootdd.sys). Note: The c:\ntbootdd.sys file is hidden, system, and read only; you must use an attribute change program to disable the hidden, system, and read only attributes. For example, using DOS, enter attrib -h -s -r c:\ntbootdd.sys. ntbootdd.sys is always located on your C drive, even if a different disk is the system disk once Windows NT is booted. For example MS-DOS is installed on your IDE disk C, and Windows NT is installed on SCSI disk D. Removing a Host Adapter ======================= Removing a host adapter can be as simple as physically removing it from the slot when your computer is shut down. Windows NT boots and functions properly in this configuration, but a warning message is generated every time you boot Windows NT. Caution: If you have removed a host adapter but still have other host adapters of the same type installed in your computer, do not use Windows NT Setup to remove the device driver. To eliminate the warning message, you must update the Windows NT software configuration, as described in these steps: 1) Select and start the Windows NT Setup program. (Its icon is usually found in the Main program group.) There is a brief pause while Windows NT Setup scans your hardware configuration. 2) Select the Options pull-down menu and select Add/Remove SCSI Adapters. The SCSI Adapter Setup program displays a list of the types of host adapters currently installed. 3) Select the type of host adapter you want to remove and click on the Remove button. When the Windows NT Setup program asks you for confirmation, click on OK. Because SCSI device drivers are loaded during system bootup and because they may be needed to load Windows NT itself, the following warning message appears: The SCSI adapter has been marked as a boot device. Removing it may cause the system not to boot. 4) If you are sure you are removing the correct host adapter type, click on OK. 5) Return to step 3 if you want to remove driver support for other types of host adapters, or click on Close to exit the SCSI adapters portion of Windows NT Setup. 6) Close the Windows NT Setup program. When the following message appears click on OK to exit: The changes you have made will not take effect until the computer is restarted. If this message does not appear, no changes have been made to the Windows NT system configuration. 7) Restart your computer. Note that Windows NT Setup does not delete the device driver from your system disk; it only updates Windows NT software configuration information so that the device driver is no longer loaded during system bootup. Updating a Device Driver ======================== If a software update is available for a particular host adapter device driver, you may update your Windows NT system without any hardware or software configuration changes by following these steps: 1) Copy the new device driver to the directory Xxxxx\System32\Drivers, where Xxxxx is the system root of Windows NT (typically named \winnt). 2) If you are updating the device driver that controls the computer boot device, copy the same driver to the file c:\ntbootdd.sys. Note: The c:\ntbootdd.sys file is hidden, system, and read only; you must use an attribute change program to disable the hidden, system, and read only attributes. For example, using DOS, enter attrib -h -s -r c:\ntbootdd.sys. 3) Shut down and restart your computer. Troubleshooting =============== The boot manager for Windows NT contains recovery logic to allow you to return to the last known good configuration. If you have changed your host adapter configuration and Windows NT no longer boots, follow these steps to recover: 1) Undo any hardware changes you have made to the computer since it was last operational. 2) Reboot the computer. Watch the display carefully during bootup. If the following message appears, press the Spacebar and follow the instructions on the screen to continue booting with the last known good configuration: Press spacebar NOW to invoke the Last Known Good menu 3) Once your computer is operational again, double check all of the hardware and software configuration changes you want to make. Look specifically for conflicts with parts of the existing system configuration that are not being changed.
