Viewing Advanced, Resources, and other settings
Devices often have other tabs, such as Advanced, Resources,
and Power Management. Most network adapters have an Advanced tab. As
shown in Figure 10, these options
can control transmission preferences. You should change these
options only if you are trying to resolve specific performance or
connectivity issues as directed by the device manufacturer or a Microsoft Knowledge Base
article. The setting that causes the most problems is Speed &
Duplex. Most of the time, you’ll want this set to Auto
Detect or Auto Negotiation. Sometimes, however, to correct a
specific problem, you must use a preset speed and duplex setting,
such as 100 Mbps Half Duplex or 1000 Mbps Full Duplex. You should do
this, however, only when this setting is recommended based on your
network configuration or the issue you are trying to
troubleshoot.
Any device that uses system resources will have a
Resources tab like the one shown in Figure 11.
The Resources tab options show the device resources that are currently assigned and their
settings. There are four types of device resources:
-
DMA The DMA channel used by
the device. Values are shown as integers, such as 02.
-
Memory Range The range of
memory addresses used by the device. Values are shown in
hexadecimal format, such as E8206000–E8206FFF.
-
I/O Range The range of I/O
ports used by the device. Values are shown in hexadecimal
format, such as 5400–543F.
-
IRQ Line IRQ line used by
the device. Values are shown as hexadecimal, such as 0xFFFFFFD8
(-40).
Devices can use multiple I/O and memory ranges. For example, the Video Graphics
Adapter (VGA) adapter on one of our computers used three I/O ranges
and three memory ranges. Additionally, multiple PCIe devices can
share the same IRQs when using Advanced Configuration and Power
Interface (ACPI) BIOS. This is because ACPI BIOS allows IRQ sharing.
