3 Routine care, SATA drive guidelines, and disassembly preparation
This chapter provides general service information for the computer. Adherence to the procedures and precautions described in this chapter is essential for proper service.
CAUTION: When the computer is plugged into an AC power source, voltage is always applied to the system board. You must disconnect the power cord from the power source before opening the computer to prevent system board or component damage.
Electrostatic discharge information
A sudden discharge of static electricity from your finger or other conductor can destroy static-sensitive devices or microcircuitry. Often the spark is neither felt nor heard, but damage occurs. An electronic device exposed to electrostatic discharge (ESD) may not appear to be affected at all and can work perfectly throughout a normal cycle. The device may function normally for a while, but it has been degraded in the internal layers, reducing its life expectancy.
Networks built into many integrated circuits provide some protection, but in many cases, the discharge contains enough power to alter device parameters or melt silicon junctions.
Generating static
The following table shows that:
● Different activities generate different amounts of static electricity.
● Static electricity increases as humidity decreases.

Electrostatic discharge information 9
Preventing electrostatic damage to equipment
Many electronic components are sensitive to ESD. Circuitry design and structure determine the degree of sensitivity. The following packaging and grounding precautions are necessary to prevent damage to electric components and accessories.
● To avoid hand contact, transport products in static-safe containers such as tubes, bags, or boxes.
● Protect all electrostatic parts and assemblies with conductive or approved containers or packaging.
● Keep electrostatic sensitive parts in their containers until they arrive at static-free stations.
● Place items on a grounded surface before removing them from their container.
● Always be properly grounded when touching a sensitive component or assembly.
● Avoid contact with pins, leads, or circuitry.
● Place reusable electrostatic-sensitive parts from assemblies in protective packaging or conductive foam.
Personal grounding methods and equipment
Use the following equipment to prevent static electricity damage to equipment:
● Wrist straps are flexible straps with a maximum of one-megohm ± 10% resistance in the ground cords.
To provide proper ground, a strap must be worn snug against bare skin. The ground cord must be connected and fit snugly into the banana plug connector on the grounding mat or workstation.
● Heel straps/Toe straps/Boot straps can be used at standing workstations and are compatible with most types of shoes or boots. On conductive floors or dissipative floor mats, use them on both feet with a maximum of one-megohm ± 10% resistance between the operator and ground.

Operating guidelines
To prevent overheating and to help prolong the life of the computer:
● Keep the computer away from excessive moisture, direct sunlight, and extremes of heat and cold.
● Operate the computer on a sturdy, level surface. Leave a 10.2-cm (4-inch) clearance on all vented sides of the computer and above the monitor to permit the required airflow.
● Never restrict the airflow into the computer by blocking any vents or air intakes. Do not place the keyboard, with the keyboard feet down, directly against the front of the desktop unit as this also restricts airflow.
● Occasionally clean the air vents on all vented sides of the computer. Lint, dust, and other foreign matter can block the vents and limit the airflow. Be sure to unplug the computer before cleaning the air vents.
● Never operate the computer with the cover or side panel removed.
● Do not stack computers on top of each other or place computers so near each other that they are subject to each other’s re-circulated or preheated air.
● If the computer is to be operated within a separate enclosure, intake and exhaust ventilation must be provided on the enclosure, and the same operating guidelines listed above will still apply.
● Keep liquids away from the computer and keyboard.
Operating guidelines 11
● Never cover the ventilation slots on the monitor with any type of material.
● Install or enable power management functions of the operating system or other software, including sleep states.

General cleaning safety precautions on page 12
before cleaning the computer.
To clean the computer case, follow the procedures described below:
● To remove light stains or dirt, use plain water with a clean, lint-free cloth or swab.
● For stronger stains, use a mild dishwashing liquid diluted with water. Rinse well by wiping it with a cloth or swab dampened with clear water.
● For stubborn stains, use isopropyl (rubbing) alcohol. No rinsing is needed as the alcohol will evaporate quickly and not leave a residue.
● After cleaning, always wipe the unit with a clean, lint-free cloth.
● Occasionally clean the air vents on the computer. Lint and other foreign matter can block the vents and limit the airflow.
Cleaning the keyboard
Follow all safety precautions in
General cleaning safety precautions on page 12
before cleaning the keyboard.
before following these procedures:
CAUTION: Use safety glasses equipped with side shields before attempting to clean debris from under the keys.
● Visible debris underneath or between the keys may be removed by vacuuming or shaking.
● Canned, pressurized air may be used to clean debris from under the keys. Caution should be used as too much air pressure can dislodge lubricants applied under the wide keys.
12 Chapter 3 Routine care, SATA drive guidelines, and disassembly preparation
● If you remove a key, use a specially designed key puller to prevent damage to the keys. This tool is available through many electronic supply outlets.
CAUTION: Never remove a wide leveled key (like the space bar) from the keyboard. If these keys are improperly removed or installed, the keyboard may not function properly.
● Cleaning under a key may be done with a swab moistened with isopropyl alcohol and squeezed out. Be careful not to wipe away lubricants necessary for proper key functions. Use tweezers to remove any fibers or dirt in confined areas. Allow the parts to air dry before reassembly.
Cleaning the monitor
● Wipe the monitor screen with a clean cloth moistened with water or with a towelette designed for cleaning monitors. Do not use sprays or aerosols directly on the screen; the liquid may seep into the housing and damage a component. Never use solvents or flammable liquids on the monitor.
●
To clean the monitor body follow the procedures in Cleaning the computer case on page 12
.
Cleaning the mouse
Before cleaning the mouse, ensure that the power to the computer is turned off.
● Clean the mouse ball by first removing the retaining plate and the ball from the housing. Pull out any debris from the ball socket and wipe the ball with a clean, dry cloth before reassembly.
●
To clean the mouse body, follow the procedures in Cleaning the computer case on page 12 .
Service considerations
Listed below are some of the considerations that you should keep in mind during the disassembly and assembly of the computer.
Power supply fan
The power supply fan is a variable-speed fan based on the temperature in the power supply.
CAUTION: The cooling fan is always on when the computer is in the “On” mode. The cooling fan is off when the computer is in “Standby,” “Suspend,” or “Off” modes.
You must disconnect the power cord from the power source before opening the computer to prevent system board or component damage.
Tools and software requirements
To service the computer, you need the following:
● Torx T-15 screwdriver
● Flat-bladed screwdriver (may sometimes be used in place of the Torx screwdriver)
● Phillips #1 screwdriver
● Diagnostics software
Screws
The screws used in the computer are not interchangeable. They may have standard or metric threads and may be of different lengths. If an incorrect screw is used during the reassembly process, it can damage the unit. HP
Service considerations 13
strongly recommends that all screws removed during disassembly be kept with the part that was removed, then returned to their proper locations.
CAUTION: Metric screws have a black finish. U.S. screws have a silver finish and are used on hard drives only.
CAUTION: As each subassembly is removed from the computer, it should be placed away from the work area to prevent damage.
Cables and connectors
Most cables used throughout the unit are flat, flexible cables. These cables must be handled with care to avoid damage. Apply only the tension required to seat or unseat the cables during insertion or removal from the connector. Handle cables by the connector whenever possible. In all cases, avoid bending or twisting the cables, and ensure that the cables are routed in such a way that they cannot be caught or snagged by parts being removed or replaced.
CAUTION: When servicing this computer, ensure that cables are placed in their proper location during the reassembly process. Improper cable placement can damage the computer.
Hard Drives
Handle hard drives as delicate, precision components, avoiding all physical shock and vibration. This applies to failed drives as well as replacement spares.
● If a drive must be mailed, place the drive in a bubble-pack mailer or other suitable protective packaging and label the package “Fragile: Handle With Care.”
● Do not remove hard drives from the shipping package for storage. Keep hard drives in their protective packaging until they are actually mounted in the computer.
● Avoid dropping drives from any height onto any surface.
● If you are inserting or removing a hard drive, turn off the computer. Do not remove a hard drive while the computer is on or in standby mode.
● Before handling a drive, ensure that you are discharged of static electricity. While handling a drive, avoid touching the connector.
● Do not use excessive force when inserting a drive.
● Avoid exposing a hard drive to liquids, temperature extremes, or products that have magnetic fields such as monitors or speakers.
Lithium coin cell battery
The battery that comes with the computer provides power to the real-time clock and has a minimum lifetime of about three years.
See the appropriate removal and replacement chapter for the chassis you are working on in this guide for instructions on the replacement procedures.
WARNING!
This computer contains a lithium battery. There is a risk of fire and chemical burn if the battery is handled improperly. Do not disassemble, crush, puncture, short external contacts, dispose in water or fire, or expose it to temperatures higher than 140ºF (60ºC). Do not attempt to recharge the battery.

SATA data cable
Always use an HP approved SATA 6.0 Gb/s cable as it is fully backwards compatible with the SATA 1.5 Gb/s drives.
Current HP desktop products ship with SATA 6.0 Gb/s hard drives.
SATA data cables are susceptible to damage if overflexed. Never crease a SATA data cable and never bend it tighter than a 30 mm (1.18 in) radius.
The SATA data cable is a thin, 7-pin cable designed to transmit data for only a single drive.
SMART ATA drives
The Self Monitoring Analysis and Recording Technology (SMART) ATA drives for the HP Personal Computers have built-in drive failure prediction that warns the user or network administrator of an impending failure or crash of the hard drive. The SMART drive tracks fault prediction and failure indication parameters such as reallocated sector count, spin retry count, and calibration retry count. If the drive determines that a failure is imminent, it generates a fault alert.
SATA hard drives 15
Cable management
Always follow good cable management practices when working inside the computer.
● Keep cables away from major heat sources like the heat sink.
● Do not jam cables on top of expansion cards or memory modules. Printed circuit cards like these are not designed to take excessive pressure on them.
● Keep cables clear of sliding or moveable parts to prevent them from being cut or crimped when the parts are moved.
● When folding a flat ribbon cable, never fold to a sharp crease. Sharp creases may damage the wires.
● Some flat ribbon cables come prefolded. Never change the folds on these cables.
● Do not bend any cable sharply. A sharp bend can break the internal wires.
● Never bend a SATA data cable tighter than a 30 mm (1.18 in) radius.
● Never crease a SATA data cable.
● Do not rely on components like the drive cage, power supply, or computer cover to push cables down into the chassis. Always position the cables to lay properly by themselves.

Memory
The computer comes with double data rate 4 synchronous dynamic random access memory (DDR4-SDRAM) dual inline memory modules (DIMMs).
The memory sockets on the system board are populated with at least one preinstalled memory module. To achieve the maximum memory support, you can populate the system board with up to 64 GB of memory configured in a high-performing dual-channel mode.
For proper system operation, the DIMMs must adhere to the following specifications:
● Industry-standard 288-pin
● Unbuffered non-ECC PC4-19200 DDR4-2400 MHz-compliant
● 1.2 volt DDR4-SDRAM memory modules
● CAS latency 17 DDR4 2400 MHz (17-17-17 timing)
● Mandatory JEDEC SPD information
The computer supports the following:
● 512 Mb, 1 Gb, 2 Gb, and 4 Gb non-ECC memory technologies
● Single-sided and double-sided memory modules
● Memory modules constructed with x8 and x16 DDR devices; memory modules constructed with x4
SDRAM are not supported
NOTE: The system does not operate properly if you install unsupported memory modules.
Populating DIMM sockets
There are four memory sockets on the system board, with two sockets per channel. The sockets are labeled
DIMM1, DIMM2, DIMM3, and DIMM4. Sockets DIMM1 and DIMM2 operate in memory channel B. Sockets DIMM3 and DIMM4 operate in memory channel A.
The system will automatically operate in single-channel mode, dual-channel mode, or flex mode, depending on how the DIMMs are installed.
NOTE: Single-channel and unbalanced dual-channel memory configurations will result in inferior graphics performance.
● The system will operate in single-channel mode if the DIMM sockets are populated in one channel only.
● The system will operate in a higher-performing dual-channel mode if the total memory capacity of the
DIMMs in Channel A is equal to the total memory capacity of the DIMMs in Channel B. The technology and device width can vary between the channels. For example, if Channel A is populated with two 1 GB
DIMMs and Channel B is populated with one 2 GB DIMM, the system will operate in dual-channel mode.
● The system will operate in flex mode if the total memory capacity of the DIMMs in Channel A is not equal to the total memory capacity of the DIMMs in Channel B. In flex mode, the channel populated with the least amount of memory describes the total amount of memory assigned to dual channel and the remainder is assigned to single channel. For optimal speed, the channels should be balanced so that the largest amount of memory is spread between the two channels. If one channel will have more memory than the other, the larger amount should be assigned to Channel A. For example, if you are populating the sockets with one 2 GB DIMM, and three 1 GB DIMMs, Channel A should be populated with the 2 GB
24 Chapter 4 Removal and replacement procedures
DIMM and one 1 GB DIMM, and Channel B should be populated with the other two 1 GB DIMMs. With this configuration, 4 GB will run as dual-channel and 1 GB will run as single-channel.
● In any mode, the maximum operational speed is determined by the slowest DIMM in the system.
Removing and installing DIMMs
IMPORTANT: You must disconnect the power cord and wait approximately 30 seconds for the power to drain before adding or removing memory modules. Regardless of the power-on state, voltage is always supplied to the memory modules as long as the computer is plugged into an active AC outlet. Adding or removing memory modules while voltage is present may cause irreparable damage to the memory modules or system board.
The memory module sockets have gold-plated metal contacts. When upgrading the memory, it is important to use memory modules with gold-plated metal contacts to prevent corrosion and/or oxidation resulting from having incompatible metals in contact with each other.
Static electricity can damage the electronic components of the computer or optional cards. Before beginning these procedures, ensure that you are discharged of static electricity by briefly touching a grounded metal object. For more information, refer to
Electrostatic discharge information on page 9
.
When handling a memory module, be careful not to touch any of the contacts. Doing so may damage the module.

Restores the backup Master Boot Record to the current bootable disk. Default is disabled.
Only appears if all of the following conditions are true:
– MBR security is enabled
– A backup copy of the MBR has been previously saved
– The current bootable disk is the same disk from which the backup copy was saved
CAUTION: Restoring a previously saved MBR after a disk utility or operating system has modified the MBR, may cause the data on the disk to become inaccessible. Only restore a previously saved
MBR if you are confident that the current bootable disk's MBR has been corrupted or infected with a virus.
● Save/Restore GPT of System Hard Drive
Enabling this feature will save the GUID Partition Table (GPT) of the system hard drive. If the GPT is subsequently changed, the user is prompted to choose whether to restore GPT.
● DriveLock

Interpreting system validation diagnostic front panel LEDs and audible codes
During the system validation phase that occurs at system startup, the BIOS validates the functionality of the following subsystems and conditions:
● AC adapter
● System board power
● Processor failure
● BIOS corruption
● Memory failure
● Graphics failure
● System board failure
● BIOS authentication failure
If an error is detected, specific patterns of long and short blinks, accompanied by long and short beeps (where applicable) are used to identify the error. These patterns will make up a two part code:
● Major – the category of the error
● Minor – the specific error within the category
NOTE: Single beep/blink codes are not used.

8 Password security and resetting CMOS
This computer supports security password features, which can be established through the Computer Setup
Utilities menu.
This computer supports two security password features that are established through the Computer Setup
Utilities menu: administrator password and power-on password. When you establish only an administrator password, any user can access all the information on the computer except Computer Setup. When you establish only a power-on password, the power-on password is required to access Computer Setup and any other information on the computer. When you establish both passwords, only the administrator password will give you access to Computer Setup.
When both passwords are set, the administrator password can also be used in place of the power-on password as an override to log in to the computer. This is a useful feature for a network administrator.
If you forget one or both passwords, you can clear all passwords by powering off the system, opening the cover, temporarily removing the PSWD jumper, and booting once. This will erase the administrator and power-on passwords. You must restore the jumper to create new passwords.
CAUTION: Pushing the CMOS button with power removed will reset the BIOS settings to factory defaults. It may be useful to back up the BIOS settings or save them as custom defaults before resetting them in case they are needed later. Back up can be performed in Computer Setup or using the BiosConfigUtility tool available from www.hp.com. See
Computer Setup (F10) Utility on page 69 for information on backing up the
BIOS settings.
Resetting the password jumper
CAUTION: Stringent security is a mode where there is no physical bypass of the password function. If enabled, removing the password jumper will be ignored. To enable this mode, change the security setting
Clear Password Jumper in Password Policies to Ignore.
If you lose or forget the password when in stringent security mode, the system can only be reset by System
Management Command. This is a way for HP Service and Support to provide a secure method to access the
BIOS and command a password reset for a specifically identified unit under the direction of the owner. This scenario may not be covered under warranty.
To prevent needing a customer service event to restore access to the system, record your configured administrator and power-on passwords in a safe place away from your computer.
To disable the power-on or administrator password features, or to clear the power-on or administrator passwords, complete the following steps:
Resetting the password jumper 117

C Statement of memory volatility
The purpose of this chapter is to provide general information regarding nonvolatile memory in HP Business computers. This chapter also provides general instructions for restoring nonvolatile memory that can contain personal data after the system has been powered off and the hard drive has been removed.
HP Business computer products that use Intel®-based or AMD®-based system boards contain volatile DDR memory. The amount of nonvolatile memory present in the system depends upon the system configuration.
Intel-based and AMD-based system boards contain nonvolatile memory subcomponents as originally shipped from HP, assuming that no subsequent modifications have been made to the system and assuming that no applications, features, or functionality have been added to or installed on the system.
Following system shutdown and removal of all power sources from an HP Business computer system, personal data can remain on volatile system memory (DIMMs) for a finite period of time and will also remain in nonvolatile memory. Use the steps below to remove personal data from the computer, including the nonvolatile memory found in Intel-based and AMD-based system boards.
NOTE: If your tablet has a keyboard base, connect to the keyboard base before beginning steps in this chapter.

d.
Select Main, select Save Changes and Exit, and then follow the on-screen instructions.
2.
What is a UEFI BIOS, and how is it different from a legacy BIOS?
The Unified Extensible Firmware Interface (UEFI) BIOS is an industry-standard software interface between the platform firmware and an operating system (OS). It is a replacement for the older BIOS architecture, but supports much of the legacy BIOS functionality.
Like the legacy BIOS, the UEFI BIOS provides an interface to display the system information and configuration settings and to change the configuration of your computer before an OS is loaded. BIOS provides a secure run-time environment that supports a Graphic User Interface (GUI). In this environment, you can use either a pointing device (Touchscreen, TouchPad, pointing stick, or USB mouse) or the keyboard to navigate and make menu and configuration selections. The UEFI BIOS also contains basic system diagnostics.
The UEFI BIOS provides functionality beyond that of the legacy BIOS. In addition, the UEFI BIOS works to initialize the computer’s hardware before loading and executing the OS; the run-time environment allows the loading and execution of software programs from storage devices to provide more functionality, such as advanced hardware diagnostics (with the ability to display more detailed system information) and advanced firmware management and recovery software.
HP has provided options in Computer Setup (BIOS) to allow you to run in legacy BIOS, if required by the operating system. Examples of this requirement would be if you upgrade or downgrade the OS.
3.
Where does the UEFI BIOS reside?
The UEFI BIOS resides on a flash memory chip. A utility is required to write to the chip.
4.
What kind of configuration data is stored on the DIMM Serial Presence Detect (SPD) memory module? How would this data be written?
The DIMM SPD memory contains information about the memory module, such as size, serial number, data width, speed/timing, voltage, and thermal information. This information is written by the module manufacturer and stored on an EEPROM. This EEPROM cannot be written to when the memory module is installed in a computer. Third-party tools do exist that can write to the EEPROM when the memory module is not installed in a computer. Various third-party tools are available to read SPD memory.
5.
What is meant by “Restore the nonvolatile memory found in Intel-based system boards”?
This message relates to clearing the Real Time Clock (RTC) CMOS memory that contains computer configuration data.
6.
How can the BIOS security be reset to factory defaults and data erased?
134 Appendix C Statement of memory volatility

Using HP Sure Start (select models only)
Select computer models are configured with HP Sure Start, a technology that continuously monitors your computer's BIOS for attacks or corruption. If the BIOS becomes corrupted or is attacked, HP Sure Start restores the BIOS to its previously safe state, without user intervention. Those select computer models ship with HP Sure Start configured and enabled. HP Sure Start is configured and already enabled so that most users can use the HP Sure Start default configuration. The default configuration can be customized by advanced users.
To access the latest documentation on HP Sure Start, go to http://www.hp.com/support . Select Find your

D Linux technical notes
HP offers a variety of Linux solutions for HP workstation customers:
● HP supports Ubuntu on some HP workstations.
● HP supports Red Hat Enterprise Linux (RHEL) on HP workstations.
● HP certifies and supports SUSE Linux Enterprise Desktop (SLED) on HP workstations.
For Linux setup and restore procedures, see the user guide for your workstation at http://www.hp.com/ support/ workstation_manuals .
●
●
●
Hyper-Threading Technology on page 137
●
NVIDIA graphics workstations on page 138
NOTE: After you set up the operating system, make sure that 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 .
136 Appendix D Linux technical notes
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 in the ALSA driver that provides audio mixing.
The performance of software audio mixing and playback is greatly improved in ALSA version 1.0.13 and later.
After the driver is installed, the optional NVIDIA and AMD graphics cards that are supported in HP workstations also provide audio functionality over HDMI. The signal can be passed through the DisplayPort connector to a monitor with audio capabilities. The vendor driver must be installed. Such a configuration might present two audio hardware choices. If you do not hear sound through the speakers, one possible reason is that the graphics card (default) is selected for audio output instead of the DisplayPort. Check 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.
Hyper-Threading Technology
The Z Series Workstations support Hyper-Threading Technology (HTT), an Intel technology that improves processor performance by enabling the processor to simultaneously perform multiple tasks. The operating system treats an HTT-enabled processor as two virtual processors and shares the workload between them when possible. This feature can be used only if the operating system support multiple processors and is specifically optimized for HTT.
To enable HTT:
1.
During startup, press F10 to enter Computer Setup (F10) Utility.
2.
Select Advanced > Performance Options.
3.
Set Intel Hyperthreading to Enable, and then press F10 to exit the menu.
4.
Select Main > 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.
Audio 137
NVIDIA graphics workstations
Some workstation configurations come with NVIDIA Quadro graphics hardware. HP recommends the use of
NVIDIA drivers for best results on Linux systems.
HP 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.com. When HP installers are used, their contents and documentation links are located in the /opt/hp/ nvidia folder.
When installing Linux on a workstation that contains an NVIDIA card, administrators should select a VESAcompatible driver to avoid the instability that is experienced with some open-source versions of the Nouveau and DRM drivers.
Open-source versions of Nouveau drivers and NVIDIA drivers cannot coexist in the same runtime environment because they use the same hardware resources. If administrators create their own Linux environments using
NVIDIA drivers but choose not to use HP-packaged versions, HP recommends that they manually append the following boot loader parameters to properly suppress the Nouveau driver at runtime (grub example below): kernel /vmlinuz ... rdblacklist=nouveau nouveau.modeset=0
This action is applied by HP installers but must be applied/restored under other circumstances.
To customize display characteristics and resolutions when the computer is using an NVIDIA driver, execute the following command:
/usr/bin/nvidia-settings
To create and manipulate the /etc/X11/xorg.conf file, execute:
/usr/bin/nvidia-xconfig
138 Appendix D Linux technical notes
AMD graphics workstations
Some workstation configurations include AMD graphics hardware. The supported Linux distributions should all have some “in-box” driver that supports the hardware well enough for the X server to run.
Here are some of the Xorg drivers that may be loaded as the server starts:
● The Radeon in-box X driver will associate with some older GPUs.
● The fbdev or vesa X driver may activate for certain other cards.
● The newer amdgpu driver may be present in some distributions but it does not support all AMD GPUs.
● There is also a generic modesetting driver in some distributions.
You may see a kernel DRM module activated for AMD graphics. The Radeon kernel module is loaded in many distributions. The older proprietary module name is fglrx, and would only be present after installing the AMD vendor driver. The newer module is amdgpu and may be present in newer kernels even without the vendor driver because it is an open-source modesetting module.
In order to achieve the best hardware acceleration for OpenGL and other APIs, the AMD advanced vendor driver (usually called amdgpu-pro) is recommended. AMD packages this driver for specific Linux releases and posts them on their website. For enterprise Linux distributions that require subscriptions, the installation process requires that either you have the installation media at hand or have registered to access online repositories. The access to repositories allows the installer to satisfy dependencies, including the basic build environment (compilers and linkers) needed to build the amdgpu-pro version of the kernel driver.
HP may at some time post a particular tested version of the amdgpu-pro driver on support pages at hp.com.
The amdgpu-pro driver lacks a settings application similar to the Catalyst Control Center that was associated with the fglrx driver.
