Windows 95/Windows NT Troubleshooting

Q:What is a miniport driver, and how do I make sure that the miniport driver for my host adapter is installed correctly ?

A:Miniport drivers are a new kind of 32-bit protect mode device driver used by Windows 95 and Windows NT to control host adapters and other kinds of devices. Windows 95 and Windows NT include a set of miniport drivers for various types of SCSI host adapters. The host adapter miniport driver is automatically installed and config- ured during Windows 95 and Windows NT installation if your host adapter is already installed.

To make sure the driver is installed correctly in systems running Windows 95, open the control panel, double-click on system, and click the Device Manager Tab. Then double-click the SCSI Control- lers icon; you should see the model name of the SCSI host adapter(s) installed in your system. (Not PCM-3420 , but AHA-152x)
