These features include: o Support for a wider variety of Ultra2SCSI PCI IC's and host adapters o Certification under Microsoft Cluster Server (Wolfpack) for AHA-2944UW and AHA-3944AUWD 3.0 Installation and Setup Instructions ----------------------------------------- This section describes installing and using the Adaptec 7800 Family Manager Set Driver (AIC78XX.SYS & AIC78U2.SYS) for Windows NT 4.0. If you are performing a first time Windows NT installation, see the "Installing Windows NT v4.0 with the FMS Driver" section below. If Windows NT is already installed on your system, see the "Updating the FMS Driver under Windows NT v4.0" section below. 3.1 Installing Windows NT v4.0 with the FMS Driver The following instructions explain how to install the Adaptec 7800 Family Manager Set v3.02, while installing Windows NT v4.0. 1 Start your system with the Windows NT Boot Diskette in the floppy drive. 2 Insert diskette #2 when prompted. After a few moments you will see a blue screen. To setup Windows NT now, press ENTER. 3 Press S to skip Windows NT Setup's auto detection of your SCSI adapter. 4 Press S again to specify an additional device. 5 Press ENTER to select Others, and insert the Adaptec 7800 Family Manager Set v3.02.4 diskette. 6 For non-Ultra2 host adapters, Select the "Adaptec AHA290x/ 291x/294x/394x/4944/AIC78xx PCI SCSI Controller(NT 4.0)" and press ENTER. For Ultra2 host adapters, Select the "Adaptec AHA-294xU2/295xU2/395xU2/AIC-789x PCI SCSI Controller(NT 4.0)" and press ENTER. 7 If you want to add other host adapters (that are not a part of the 7800 Family), do so at this time by pressing 'S' and repeating step 5 for each additional adapter and inserting the appropriate disk provided by the hardware manufacturer. The Adaptec 7800 Family host adapters use the same driver; it is not necessary to install the AIC78XX.SYS or AIC78U2.SYS driver again. 8 Press ENTER to continue with the Windows NT operating system setup. Follow the instructions given on screen and in the Windows NT installation documentation. 3.2 Updating the FMS Driver under Windows NT v4.0 Follow these instructions only if Windows NT v4.0 is already installed. 1 Click the Start button on the Winows NT task bar, and the point to Settings. 2 Open the Control Panel, double-click on SCSI Adapters. 3 Select the Drivers tab, and click the Add button. 4 In the "Install Driver" window, click the Have Disk button. 5 Insert the Adaptec 7800 Family Manager Set driver v3.02.4 diskette. 6 At the "Copy manufacturer's files from" text box, type a:\winnt\4_0, and click OK. 7 At the Install Driver window, select the driver, then click OK. 8 In response to "Do you want to use the currently installed driver(s) or install new one(s)", select the New button. 9 Again type a:\winnt\4_0 and click continue. The driver is now installed. 10 You must restart your computer for the changes to take effect. Click Yes to restart your computer. Click No to return to the SCSI Adapters window. 3.3 Removing a Host Adapter from Windows NT v4.0 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 the following steps: 1 Open the Control Panel, double-click on SCSI Adapters. 2 Select the Drivers tab. 3 Select the Driver you wish to remove. a. For non-Ultra2 host adapters: Select the driver you plan on removing and click the Remove button. The driver will appear as one of the following: "Adaptec AHA290x/291x/294x/394x/4944/AIC78xx PCI SCSI Controller (NT 4.0)" or "Adaptec AHA-294x/AHA-394x/AHA-4944 or AIC-78xx PCI SCSI Controller (NT 4.0)" or "Adaptec AHA-294X/AHA-394X or AIC-78XX PCI SCSI Controller" b. For Ultra2 host adapters: Select the driver you plan on removing and click the Remove button. The driver will appear as the following: "Adaptec AHA-294xU2/295xU2/395xU2/AIC-789x PCI SCSI Controller(NT 4.0)" 4 If you are sure you are removing the correct host adapter type, click Yes. 5 You must restart your computer for the changes to take effect. Click Yes to restart your computer. Click No to return to the SCSI Adapters window. 3.4 Swapping a Host Adapter for Windows NT v4.0 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 and before you make the hardware changes. (NOTE: If you do not install the driver that comes with the new host adapter, it may result in Windows NT failing to boot.) 1 Install the driver for the new host adapter by following the steps in Updating Windows NT with the Driver, 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. However, if you leave the driver in, the system alerts you with an error message of the extra device driver every time you boot. See Removing a Host Adapter above. 2 Once the new device driver is installed, shut down Windows NT and replace the existing host adapter. 3 Restart your computer and Windows NT. It is possible that some drive letter assignments may change from the previous configuration. 4.0 Configuration Information ------------------------------- 4.1 Additional notes o If disconnection is disabled under SCSISelect for a hard disk device, the system may hang if the hard disk device supports tagged queuing. It is recommended to always enable disconnection for hard disk devices. By default, disconnection is enabled so no action is required. If for some unique requirements disconnection has to be absolutely disabled for hard disk devices, you can turn off tagged queue requests by editing the Windows NT Registry. You can do so by following these instructions: 1 Select Run from the Start button (Windows NT 4.0). 2 Enter REGEDT32 to run the Registry Editor. 3 a. For non-Ultra2 host adapters: Open \HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\aic78xx. b. For Ultra2 host adapters: Open \HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\aic78u2. 4 Create a key named Parameters by selecting Add Key from the Edit pull-down menu and entering "Parameters" (without quotations) in the edit-box for Key Name. Leave the Class edit-box blank. 5 Open Parameters and create a key named Device by selecting Add Key from the Edit pull-down menu. Enter "Device" (without quotations) in the Key Name edit-box. Leave the Class edit-box blank. 6 Open Device. Select the Add Value option from the Edit pull-down menu. In the Value Name edit-box, enter "DisableTaggedQueuing" (without quotations). Select the Data Type REG_SZ from the droplist combo box. 7 Shutdown and restart Windows NT. 8 Set Enable Disconnection to No for your particular device(s) in SCSISelect during bootup. (See your Host Adapter manual on how to use SCSISelect). o If the logical driver letters assigned by the BIOS change when the NT operating system is running, it's not an error. To preserve drive letter assignments between BIOS and NT, run the NT disk administrator and choose permanent drive letters assignments as an option. NT will then preserve logical driver letter assignments across boots and adapters. o 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. Press spacebar NOW to invoke the Last Known Good menu Follow the instructions on the screen to continue booting with the last known good configuration. For Windows NT 4.0 only, hit the letter "L", to switch to the last known good configuration. 3 Once your computer is operational again, 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. 4.2 NT SCSI Command Line Options The following table shows driver-specific command line options: NAME DEFINITION VALID DEFAULT VALUES VALUE ----------------------------------------------------------------------------- MaximumSGList Specify maximum number of 17 - 255 17 (type=REG_DWORD) scatter-gather elements for Windows NT 4.0 only DisableTaggedQueuing Disables Tagged Queueing None (type=REG_SZ) To enter Windows NT SCSI-specific parameters, follow these steps: 1 Select Run from the Start button (Windows NT 4.0). 2 Enter REGEDT32 to run the Registry Editor. 3 a.
