a configuration might present two audio hardware choices. If you do not hear sound through the
speakers, one possible reason is that the graphics card (default) is selected for audio output instead
of the DisplayPort. Check the audio settings (for example, Sound in gnome-control-center).
In some systems, embedded Intel HD graphics may also present a similar HDMI audio device that
can be used through the DisplayPort interface. No proprietary driver is needed for this device, just a
sufficiently recent kernel.
Network cards
All HP workstations include one or two integrated network interface controllers. Some support
optional NICs. Most Linux distributions have drivers for these interfaces.
Hyper-Threading Technology
Your workstation supports Hyper-Threading Technology (HTT), an Intel technology that improves
processor performance by enabling the processor to simultaneously perform multiple tasks. The
operating system treats an HTT-enabled processor as two virtual processors and shares the
workload between them when possible. This feature can be used only if the operating system
supports multiple processors and is specifically optimized for HTT.
To enable HTT:
1.
During startup, press
f10
to enter Computer Setup (f10) Utility.
2.
Select Advanced > Device Options.
3.
Set Hyper-Threading to Enable, and then press
f10
to exit the menu.
4.
Select File > Save Changes and Exit.
5.
Restart the system.
NOTE:
On most recent Linux distributions (including RHEL 6, SLED 11, and updates to those
streams), the kernel automatically detects that HTT is enabled and works correctly.
