For each DriveLock-capable drive, select a drive by pressing F10 to accept. 5.
Password security The power-on password prevents unauthorized use of the computer by requiring the entry of a password to access applications or data when the computer is powered on or restarted. The setup password specifically prevents unauthorized access to the Computer Setup (F10) Utility and can also be used as an override to the power-on password. An administrator can enter the setup password at the prompt for the power-on password and gain access to the computer.
Establishing a power-on password using computer setup Establishing a power-on password through Computer Setup (F10) Utility prevents access to the computer when power is connected, unless you specify the password. When a power-on password is set, Computer Setup (F10) Utility presents Password Options in the Security menu. The password options include Network Server Mode and Password Prompt on Warm Boot.

A Linux technical notes HP offers a variety of Linux solutions for HP workstation customers: ● HP certifies and supports Red Hat Enterprise Linux (RHEL) on HP workstations. ● HP certifies SUSE Linux Enterprise Desktop (SLED) on HP workstations. ● HP offers a SLED 11 preload on some Z Series workstations. For Linux setup and restore procedures, see the user guide for your workstation at http://www.hp.com/support/workstation_manuals.
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.
NVIDIA Graphics Workstations Some HP Z1 workstation configurations come with NVIDIA Quadro graphics hardware. HP recommends the use of NVIDIA proprietary graphics drivers for best results on Linux systems. Driver versions of 295.20 or higher are qualified for HP Z1 workstation applications. HP also provides recommended versions of the drivers with RPM-compatible installers for RHEL and SLED distributions. These are available from the HP Installer Kit for Linux and from workstation driver repositories on hp.
B Configuring RAID devices This appendix contains the following information: ● Instructions on setting up and managing SATA RAID volumes in Windows ● A summary of software RAID considerations in Linux and references to procedures on configuring software RAID for Linux The following SATA RAID configurations are supported on workstations that have two 2.5-in hard drives.
Configuring the system BIOS to enable embedded SATA RAID functionality To set up a RAID configuration, the SATA emulation mode must be set to AHCI+RAID in the BIOS setup menu. This is the default setting. If the mode has been changed, follow these steps to change it back. 1. During startup, press F10 to enter Computer Setup (F10) Utility. Use the arrow keys to navigate and select options. 2. Select a language from the list, and then press Enter. 3.
Creating RAID volumes Follow these steps to create RAID volumes. 1. Press Ctrl+l when prompted to enter the Intel Rapid Storage Technology utility. Use the arrow keys to navigate and select options. NOTE: If only a single hard drive is attached, the utility does not execute. No message is displayed. 2. Select 1. Create RAID Volume, then press Enter. 3. Enter the desired RAID volume name in the Name field, and then press Tab. 4. Select a level in the RAID Level field, and then press Tab. 5.
Software RAID solution This section provides a summary of software RAID considerations when running the Linux operating system, as well as references to configuration procedures. Software RAID considerations The Linux kernel software RAID driver (called md, for multiple device) offers integrated software RAID without the need for additional hardware disk controllers or kernel patches. All that is required are multiple hard disks and a small amount of setup.
