hardware choices. If you do not hear sound through the speakers, one possible reason is that the NVIDIA audio
device has been chosen by default. Verify 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. The HP Z1 G2 Workstation
includes a PCI Express Mini Card that implements both wireless LAN and Bluetooth. The iwlagn driver supports
the wireless LAN; in most distributions, the Network Manager automatically senses that wireless networks
are available. Bluetooth support is also available in many Linux distributions.
Hyper-Threading Technology
The Z Series workstations support Hyper-Threading Technology (HTT), an Intel-proprietary technology that
improves processor performance through parallelization of computations (doing multiple tasks at once). The
operating system treats an HTT-enabled processor as two virtual processors and shares the workload
between them when possible. This feature requires that the operating system support multiple processors
and be specifically optimized for HTT.
To enable HTT:
1.
During startup, press
F10
to enter Computer Setup (F10) Utility. Use the arrow keys to navigate and
select options.
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 to enable HTT.
NOTE:
On most recent Linux distributions, the kernel automatically detects that HTT is enabled and works
correctly.
