NOTE: After you set up the operating system, make sure the latest BIOS, drivers, and software
updates are installed.
CAUTION: Do not add optional hardware or third-party devices to the workstation until the
operating system is successfully installed. Adding hardware might cause errors and prevent the
operating system from installing correctly.
System RAM
HP supports different amounts of total RAM in various HP workstations based on the number of
hardware DIMM slots and the capabilities of the system. The total memory supported for each
configuration is listed in the Hardware Support Matrix for HP Linux Workstations at
http://www.hp.com/support/linux_hardware_matrix.
Audio
All HP workstations come with built-in audio hardware. The audio hardware is supported by the
Advanced Linux Sound Architecture (ALSA) drivers included with all modern Linux distributions.
The audio hardware provides basic playback and recording features. The ability to simultaneously play
audio from multiple sources, such as applications and CDs, is provided by software mixing functionality
in the ALSA driver. The performance of software audio mixing and playback functionality is greatly
improved in ALSA version 1.0.13 and later drivers.
