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.
