8. Repeat steps 4 through 8 for each SCSI host adapter installed on the system. If a driver supports more than one
host adapter, the driver only needs to be installed one time.
9. Press <Enter> to continue with Windows NT Setup.
10. When you are prompted to install the Adaptec 7800 Family Manager Set for Windows NT 4.0, use the SCSI and
video controller driver diskette you created for Windows NT from the Dell OpenManage Server Assistant CD.
11. When you are prompted to install the RAID controllers, use the RAID driver diskette you created for Windows
NT from the Dell OpenManage Server Assistant CD.
12. Click Yes when prompted to restart the system, and remove the diskette from the diskette drive.
After the system reboots, the new drivers are active. Some drive assignments may have changed from the previous
configuration. Be sure to complete the Windows NT installation by performing the following tasks:
Install Windows NT Service Pack 3.0
Install the accelerated graphics port (AGP) video drivers
Install network interface controller (NIC) drivers
Refer to the Windows NT installation documentation for details.
Removing a Host Adapter
CAUTION: If you have removed a host adapter but still have other host adapters of the same type installed
in your computer, do not remove the device driver. The other host adapters still need the driver to function
properly.
To remove a PCI SCSI controller, remove the expansion card from its slot when your computer is shut down. Windows
NT boots and functions properly in this configuration. However, if an unused device driver remains on the system, a
warning message is generated and an entry is made into the system log file every time you boot Windows NT. To
eliminate the warning message, you must update the Windows NT software configuration as follows:
1. Click the Start button, point to Settings, and click Control Panel.
2. Double-click the SCSI Adapter icon.
The SCSI Adapter window appears.
3. Select the Drivers tab. A list of all installed host adapters appears.
4. Highlight the driver to be removed.
5. When you are sure you are removing the correct host adapter, click Remove.
Because SCSI device drivers are loaded during system start-up and because they may be needed to load
Windows NT itself, a message may appear warning you that Windows NT may not start if you remove the SCSI
adapter.
6. Confirm the removal by clicking Yes.
7. Return to step 3 if you want to remove driver support for other types of host adapters, or click OK to continue.
8. When the following message appears, click OK to exit the Control Panel:
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.
9. Restart your computer.
Swapping a Host Adapter
The procedure for swapping a host adapter depends upon whether the new host adapter uses the same device driver as
the previous one.
If the same device driver is used, shut down the computer, physically swap out the host adapter, and restart the
computer. The device driver for the previous host adapter will function correctly for the new host adapter. For example,
because both the AIC-7890 host adapter and the AHA-2940U2W host adapter use the Adaptec aic78u2.sys driver, you
