This chapter explains how to install the Adaptec 7800 Family Manager Set and aic78u2.sys driver for
Windows NT. The aic78xx.sys driver supports all Adaptec 7800 Family Ultra2 SCSI (and earlier) host
adapters, and the aic78u2.sys driver supports all Ultra2 SCSI adapters.
If you are performing a first time Windows NT installation, see Installing the Driver When installing Windows
NT. If Windows NT is already installed in your system, see Installing the Driver When Windows NT is
Already Installed.
Installing the Driver When Installing Windows NT
A version of the aic78xx.sys driver (Ultra2 SCSI) driver is embedded (Included) in the Windows NT 3.5x and
4.0 installation disks (or CD-ROM). During a normal Windows NT installation, the 7800 Family host adapter
is detected in your system and the embedded driver is automatically installed.
Note:
If you are booting from a 7800 Family host adapter and you are unable to install
the embedded aic78xx.sys driver by performing a Windows NT installation, follow the
instructions for completing a fresh Windows NT installation.
The aic78u2.sys driver (Ultra2 SCSI) is not embedded on the Windows NT 3.5x and 4.0 installation disks (or
CD-ROM) and must be installed after Windows NT has been installed. When completing the Windows
installation, you can update the driver by following the instructions in Installing the Driver When Windows NT
is Already Installed.
