Device Manager
Error Codes
If there is a problem with one of your devices, Windows will list the
device with one of the following symbols in the Device Manager (Control Panel
->
System -> Device Manager tab):
 This
indicates a disabled device. While the device
is physically present in the computer, a protected
mode driver has not been loaded into memory for it
 The
black exclamation mark over a yellow circle
indicates that there is a problem with this
device. An error code will be displayed providing
more information.
 This
indicates that a Compatible Driver has been
loaded for this device and that it may not have
full functionality. This warning will only appear
in the Windows Me Device Manager
 The
Automatic Settings feature of Device Manager
has been disabled and the resources for this
device have been set manually. This does not
indicate an error or a disabled state.
Note: Some sound cards and video adapters do not report all
the resources they are using to Windows. 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 to 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).
Error Codes:
Code 1: This code means the system has not had a chance to
configure the device. To resolve the problem, follow the instructions in
the Device Status box. In addition, you may be able to resolve this
issue by removing the device in Device Manager, and then running the Add
New Hardware wizard from Control Panel.
Solution button: Update Driver
Code 2: Depending on which device is failing, you may see
either of two different messages. This code means that the device loader
(DevLoader) did not load a device. When this device is a Root Bus
DevLoader (for example, ISAPNP, PCI, or BIOS), the following message is
displayed:
Windows could not load the driver for this device because the computer
is reporting two <type> bus types. (Code 2)
Contact your computer manufacturer to get an updated BIOS for your
computer.
where <type> is ISAPNP, PCI, BIOS, EISA, or ACPI.
Solution button: None
When the device is not a root bus DevLoader, the following message is
displayed:
The <type> device loader(s) for this device could not load the
device driver. (Code 2)
To fix this, click Update Driver to update the device driver.
where <type> is the DevLoader such as FLOP, ESDI, SCSI, and
so on.
Solution: Update Driver
In addition to following the recommended solution, try removing the
device from Device Manager, and then running the Add New Hardware wizard
from Control Panel.
Code 3: This code means the driver for this device is bad,
system is running low on memory.
Solution: Update Driver
As an alternative, use Device Manager to remove the device and then
run the Add New Hardware wizard in Control Panel.
Code 4: This code means the .inf file for this device is
incorrect or the registry may be damaged. For example, the .inf file
specifies a field that should be text, but is binary instead. To resolve
this error code, use Device Manager to remove the device and then run
the Add New Hardware wizard in Control Panel. If you continue to receive
this error code, please contact the hardware's manufacturer for an
updated .inf file.
Solution: Update Driver
Code 5: This code means there was a device failure due to the
lack of an arbitrator. If a device requests a resource type for which
there is no arbitrator, you receive this error code. To resolve this
error code, update the driver as suggested, or use Device Manager to
remove the device and then run the Add New Hardware wizard in Control
Panel.
Solution: Update Driver
