the model name of the host adapter does not appear under Device Manager?

A:If the SCSI controllers icon or your host adapter's model name (AHA-152X, not PCM-3420) do not appear, open Control Panel and double-click the Add New Hardware icon. Let Windows search for the host adapter by selecting Yes on the second screen of the Add New Hardware Wizard.

If Windows does not detect the host adapter, run the Add new Hardware Wizard again, select No on the second screen of the wizard, then select SCSI controllers on the next screen. Select the name of your host adapter when it appears (Select Adaptec AHA- 152x).

If the name of your SCSI host adapter does not appear, you may be able to find its miniport driver on the Windows 95 CD-ROM. Follow these steps:

1.Place the Windows 95 CD-ROM in your CD-ROM driver and run the Add New Hardware wizard.

2.Select No on the second screen, and select SCSI controllers on the next Screen.

3.Click on the Have Disk button, then click the Browser Button.

4.Look in the \drivers\storage directory of the CD-ROM and select the name of your SCSI host adapter (AHA-152x) if it appears.

Q:What if a yellow exclamation point and red X appears in Device Manager in front of my host adapter?

A:This means there is some kind of resource problem.

First, see if the name of host adapters appear that are not actually installed in your computer. If so, select the name and click Remove. If a red X appears in front of your host adapter name, remove all the host adapter references under SCSI controllers and run Add New Hardware, as described in the previous question/answer. If a yellow exclamation point appears in front of your host adapter name, the resources that the driver use probably do not match the resources used by the hardware. Double-click the host adapter name, then click on the Resource tab. Deselect the Use automatic settings box and edit the resources (Interrupt Request, Direct Memory Access, etc.), so they match those used by the host adapter. If the problem still remains, there is probably a hardware resource conflict between
