SUMMARY
You can use Device Manager to examine and change software-configurable
devices. This article lists steps you can use to troubleshoot hardware
configuration problems using Device Manager.
If the device uses jumper pins or dip switches, you must configure the
device manually.
MORE INFORMATION
To view Device Manager, follow these steps:
- Click the Start button, point to Settings, then click Control Panel.
- Double-click the System icon.
- Click the Device Manager tab.
Troubleshooting Information
- If there is a problem with a device, it is listed in the hardware tree
list under Computer. The problem device has a symbol indicating the
type of problem:
A black exclamation point (!) on a yellow field indicates the device
is in a problem state. A device in a problem state can be functioning.
A problem code explaining the problem is displayed for the device.
A red "X" indicates a disabled device. A disabled device is a device
that is physically present in the system, consuming resources, but does
not have a protected-mode driver loaded.
A blue "i" on a white field on a device resource in Computer properties
indicates that Use Automatic Settings is not selected for the device and
that the resource was manually selected. It does not indicate a problem
or disabled state.
NOTE: Some sound cards and video adapters do not report all the
resources they are using to Windows 95. This can cause Device Manager
to show only one device in conflict, or no conflicts at all. This can
be verified by disabling the sound card, or using the standard VGA
video driver too see if the conflict is resolved. (This is a known
problem with S3 video cards and 16-bit Sound Blaster sound cards, or
those sound cards using Sound Blaster emulation for Sound Blaster
compatibility.)
- When you select a specific device in Device Manager, then click
the Properties button, you see a property sheet. The property sheet
has a General tab.
NOTE: Some devices may have other tabs besides the General tab. Not
all property sheets have the same tabs; some devices may have a
Resource tab, Driver tab, and Settings tab, or some combination of
these.
At the top of the property sheet, there is a description of the device.
When you click the Resource tab, the window in the middle of the tab
indicates which resource types are available for the selected device.
The scroll box at the bottom of the contains a Conflicting Device list.
This list indicates a conflict with an error code.
- Note the Use Automatic Settings check box. If Windows 95 successfully
detects a device, this check box is selected and the device should
function correctly. However, if the resource settings are based on
Basic Configuration <n> (where <n> is any number from 0 to 9), it may
be necessary to change the configuration by selecting a different basic
configuration from the list. If the particular configuration you want
for the device is not listed as a basic configuration, it may be
possible to click the Change Settings button to manually adjust the
resource values.
For example, to edit the Input/Output Range setting, use these steps:
1. Click the Use Automatic Settings check box to clear it.
2. Click the Change Setting button.
3. Click the appropriate I/O range for the device.
Notes
- If you click Computer, then Click properties, you see a property sheet
with a View Resources and a Reserve Resources tab.
You can use the Reserve Resources tab to exclude a resource from use by
Windows 95.
The View Resources tab displays the resources allocated by Windows 95
or inherited from a Plug and Play BIOS or PCI bus computer.
- To disable a device in Device Manager, click the Original Configuration
(Current) check box to clear it on the General tab in the device's
properties.
