HP Z1 Maintenance And Service Guide

After the NVIDIA proprietary driver is installed, the optional NVIDIA graphics devices supported in the
HP Z1 Workstation also provide audio functionality over HDMI, which can be passed through the
external DisplayPort connector to a monitor with audio capabilities. Such a configuration may present
two audio 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. Check the audio settings (for example,
Sound in GNOME Control Center).
Network cards
All HP workstations include one or two integrated network interface controllers. The HP Z1 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 (including RHEL 5, RHEL 6, SLED 11, and updates to those
streams), the kernel automatically detects that HTT is enabled and works correctly.
