    The value of a workstation when compared to a business desktop PC is characterized by several things:

    • High-performance 3D OpenGL graphics and professional 2D multi-display graphics - for the ultimate visualization and design interaction experience
    • Professional ISV certifications on technical applications - for guaranteed compatibility and reliability, optimized performance, and supportability
    • High-performance I/O devices and components (including SCSI hard disk drives, controllers, RAID, etc) - for superior application performance
    • Choice of operating system (Microsoft Windows XP or Red Hat Linux) - for flexibility of working environments and IT infrastructure

    The following table outlines some of the specific differences between the HP Workstation xw4300 and the HP Compaq dc7600 Business Desktop:

  • What are the benefits of Intel High Definition Audio?

    Intel High Definition (HD) Audio delivers significant improvements over previous generation integrated audio and sound card. Intel HD Audio hardware is capable of delivering the support and sound quality for up to eight channels at 192 kHz/32-bit quality, while the AC'97 specification can only support six channels at 48kHz/20-bit. In addition, Intel HD Audio is architected to help prevent the occasional glitches or pops that other audio solutions can have by providing dedicated system bandwidth for critical audio functions.

    Intel HD Audio features multi-streaming capabilities that give users the ability to send two or more different audio streams to different places at the same time, from the same workstation. This addresses the need to play back two different audio tracks, such as a CD and a DVD simultaneously.

    Intel HD Audio also provides improvements that support better jack retasking. The workstation can sense when a device is plugged into an audio jack, determine what kind of device it is, and change the port function if the device has been plugged into the wrong port. For example, if a microphone is plugged into a speaker jack, the computer will recognize the error and can change the jack to function as a microphone jack.

  • Will I have to change my golden image on the HP xw4300 Workstation?

    Yes. The HP xw4300 is a completely new platform based on new technology from Intel. Most of the system drivers will be different than those used on the HP xw4200, therefore you will have to create new golden images. The standard suite of manageability software (Altiris Express, CCM, etc.) will be available to help with this image building process.

 Intel Pentium D Dual-Core Processor
  • What are the benefits of dual-core processors?

    The Intel Pentium D dual-core processor provides double the processing resources in the same footprint. Dual-core processors are ideal for usage models requiring multitasking (creating animation/rendering - DCC); working on spreadsheets while listening to music (power office); or those using applications that can split a task across processors (multithreaded).

  • Will the dual-core processor offer any performance improvement over single-core processors?

    The dual-core processors perform best on multi-threaded applications (like certain renderers in DCC), or in environments where multiple applications are running at once. Early indications are that the performance improvement for multi-threaded or multi-tasking applications is about 15-30% compared to an equivalently priced single-core processor.

 Memory
  • What memory is used on the HP xw4300? Is it the same memory used on the HP xw4200?

    Yes and no. The HP xw4300 uses DDR2-533 ECC memory technology for memory configurations above 4 GB. However, higher bandwidth DDR2-667 ECC memory is also available on HP xw4300 in configurations up to 4 GB. However, DDR2-533 non-ECC is also available on the HP xw4300 for some smaller memory capacity configurations. Offering three types allows you to choose the memory speed and configuration that meets your price and performance needs.

  • Why do I sometimes see memory in terms of PC2-5300? How does this relate to memory bandwidth?

    Clock rate is directly proportional to memory bandwidth. The bandwidth of 667 MHz DDR2 memory is calculated as 667 MHz * 8 bytes per channel = 5,336 MB/s or 5.3 GB/s. For simplicity, the value is rounded and thus referred to as PC2-5300 DDR memory. The "2" after PC just identifies this memory as DDR2 memory. This nomenclature is sometimes more accepted in the industry.

    The memory bandwidth of the system is improved upon by implementing dual-channel memory architecture. Above, notice the factor "8 bytes per channel". By implementing two channels you can essentially double your bandwidth. Instead of a single DIMM working alone, a pair of DIMMs essentially works together to split up the data exchange to and from the rest of the system. On the HP xw4300 the dual-channel memory architecture results in unprecedented memory bandwidths on a personal workstation. With PC2-5300 DDR (667MHz) memory, the system's theoretical memory bandwidth is an astounding 10.7 GB/s. Relative to the older HP xw4200's memory bandwidth of 8.5 GB/s, this is a tremendous improvement.

  • Does the large DDR2-667 memory bandwidth (10.7 GB/s) really help system performance if the processor bandwidth is only 6.4 GB/s?

    Yes. Not all data is transferred between the processor and the system memory. For some tasks, system I/O and graphics pass data to the system memory. With the bandwidth headroom these tasks are carried out without interrupting the data flow between the memory and the processor. In benchmarks, we've seen performance improvements as much as 5% resulting from the faster memory. In addition, this performance gain scales with the processor. So, as the processors get faster, the bandwidth benefit will become more important.

  • How does this memory bandwidth impact the HP xw4300 system performance?

    Many technical applications require huge amounts of memory bandwidth, especially those that use 3D graphics or that have a large percentage of floating point calculations. These applications will benefit from the massive memory bandwidth provided by the HP xw4300.

    Memory latency is another very important factor. At the highest level, latency is a measure of how long it takes the memory subsystem to respond to a cache miss in the processor. The lower (shorter) the memory latency, the better the application performance, especially for applications that "thrash the cache."

  • Does the memory for the HP xw4300 have to be ordered in pairs? What is the maximum memory configuration?

    No, but to take advantage of the dual-channel memory architecture, memory must be installed in pairs. However, a single DIMM will work in the system (i.e. you could put 1x256 MB in the system). It is highly recommended that memory be added in pairs, as the performance benefit is substantial. The 1x256 non-ECC is the only single-DIMM configuration offered.

    When installing memory in the HP xw4300, pairs must be matched in size and speed (i.e. 2x256 MB/667 MHz, not 1x256 MB/533, 1x512 MB/667) and multiple pairs must be matched in speed. The HP xw4300 has 4 DIMM slots (2 dual-channels) and supports up to 8 GB of physical memory.

  • Does the HP xw4300 offer ECC and non-ECC memory? If so, what speeds are/will be offered?

    Yes. The HP xw4300 offers both ECC and non-ECC memory. The following table outlines what memory is/will be available.

    DIMM size / speed 128MB 256MB 512MB 1GB 2GB
    DDR2 667 MHz , ECC Not available Available Available Available Not available
    DDR2 533 MHz , ECC Not available Available Available Not available Available
    DDR2 533 MHz , non-ECC Not available Available Available Not available Not available


  • What is ECC memory? Why is ECC memory important?

    "ECC" stands for Error Correcting Code or Error Checking and Correction, memory depending on which resource you refer to. ECC memory modules have an extra chip that performs a comparison of the data that is read in and written out. This chip has the capability of detecting single and multiple bit errors and correcting single bit errors on the fly. If this extra chip detects a single bit error, it will correct the discrepancy and the system will continue to function without any interruption. If a multiple-bit error (which is extremely uncommon) is detected, the memory module will issue a non-maskable interrupt (NMI) which will shutdown the system, avoiding any data corruption in the system. Single- and multiple-bit data errors can go undetected without ECC memory.

    Data integrity is always important, but when you are designing an airplane or automobile part, under a tight deadline on your TV commercial production, analyzing population densities for domestic policy reform, or managing your clients' financial portfolios of millions of dollars, data integrity is absolutely vital. And in today's cut-throat competitive environment, work flow efficiency and utilization rates are also crucial. HP workstations, including the HP xw4300, offer ECC memory which provides an extra level of data integrity, reliability, and greater system uptime.

 Drives
  • Is the floppy drive really optional on the HP xw4300?

    Yes. For ultimate price flexibility and/or security concerns from many customers, we now offer systems with or without the floppy drive. With the advancement of technologies like USB Disk Keys, bootable CD-ROMs/CDRWs, external storage, etc. the necessity of a floppy drive has really declined over the past few years and many customers simply don't need them anymore. We offer the flexibility should you decide it is not needed on your HP xw4300.

  • Is the optical drive really optional on the HP xw4300?

    Yes. For ultimate price flexibility and/or security concerns from many customers, we now offer systems with or without an optical drive. Microsoft has lifted a requirement that forced the integration of an optical device on previous systems, so this is now possible for the first time on the HP xw4300.

  • Are legacy SATA-I hard drives available on the HP xw4300? What hard drives are available?

    Yes. While most of the SATA drives offered on the HP xw4300 will be the new SATA 3.0 Gb/s technology, some of the SATA drives are legacy (specifically, the 40 GB/7200 rpm and the 74 GB/10K rpm). The controller is backward-compatible, and will work with SATA 1.5 Gb/s drives. We also offer a full selection of SCSI hard drives.

  • Does the HP xw4300 offer and support SATA 3.0 Gb/s hard drives?

    Yes. The HP xw4300 has an integrated 4-channel SATA 3.0 Gb/s controller for Serial ATA hard drives. We offer the following SATA 3.0 Gb/s hard drives: 80 GB, 160 GB, 250 GB, and 500 GB (7200 rpm). We also offer a full selection of SCSI hard drives.

  • Does the HP xw4300 support Serial ATA (SATA) RAID?

    Yes. The chipset used on the HP xw4300 has integrated 4-channel SATA controller with Native Command Queuing (NCQ) and RAID support for RAID 0, (striped), RAID 1 (mirrored), RAID 5 (parity), and RAID 10 (striped and mirrored). You can choose to have a high performance RAID 0 array of hard drives where data is striped across multiple hard drives (this RAID method greatly improves data access times and system performance). You can choose to have a highly reliable RAID 1 array of hard drives, where data is duplicated to multiple hard drives at once (this RAID method essentially creates a backup copy of all your data in real time). You can choose to implement a RAID 5 array, which protects against data loss and provides faster throughput. Data is distributed across at least two hard disks, with error correction information stored on an additional disk. Finally, you can choose to implement a RAID 10 array, which offers the advantages of RAID 0 and RAID 1 by utilizing four hard disks.

  • What is the value of Native Command Queuing or NCQ?

    NCQ is a performance enhancement for hard drives. NCQ reorganizes read/write commands in such a way that they can be executed in a more efficient manner than typical synchronous execution. NCQ performance improvement is highly dependant on the type of application and load, but can be as high as 20%.

  • What SCSI drives and controllers are offered on the HP xw4300?

    We continue to offer a wide selection of SCSI disk drives and controllers. The faster spindle speeds (10K or 15K rpm) and the high bandwidth controllers (320 MB/s) result in very fast access to your data. We offer two different PCI SCSI controllers: an entry U320 SCSI controller with basic hard drive connectivity/control, and a full-featured U320 SCSI controller with an external connector and host RAID capability. Both cards are single channel, 32-bit cards. We offer the following SCSI drives: 73 GB/10K, 146 GB/10K, 300 GB/10K, 36 GB/15K, and 73 GB/15K rpm.

  • What optical drives are available with the HP xw4300? What software is bundled with these drives?

    The following table outlines what optical drives will be available at launch and what software will be bundled with each drive.

  • Is the chassis for the HP xw4300 the same chassis used on the HP xw4200? Is it still convertible?

    Yes. The HP xw4300 uses the same award-winning chassis as the HP xw4200. The HP xw4300 is housed in an intelligently designed chassis with tool-less access for ease of servicing, upgrading and maintenance. It is still convertible from a desktop orientation to a minitower orientation. The HP xw4300 is rackable and shelving kits are available

  • What ports does the HP xw4300 have on the front bezel?

    The front bezel on the HP xw4300 has the following ports available: (1) IEEE 1394a port*, (2) USB 2.0 ports, (1) microphone port, and (1) headphone port.

    *The IEEE 1394a port is only active when the optional IEEE 1394 PCI card is installed in the system.

  • What is the "Solenoid Hood Lock"? Is it available on the HP xw4300?

    The "Solenoid Hood Lock" is an electro-mechanical lock that is activated through the manageability software on the workstation. Instead of a physical key, the chassis is locked through a password by the local user or the remote system administrator.

 Intel Extended Memory Technology (EM64T)*
  • How will I benefit from Intel's Extended Memory 64 Technology?

    With Intel EM64T, you will be able to go far beyond the current 32-bit limitation of 4 GB of addressable memory space which will aid in your design and manipulation of large data sets or models.

    An EM64T enabled workstation should provide leading performance for many 32-bit applications. Although not all 32-bit applications run as normal on a 64-bit operating system, many will, providing a "friendly" transition path from 32-bit to 64-bit computing. It is advised to pre-test your applications by using Microsoft's 64-bit 120 day free trial before you order EM64T.

  • Will my 32-bit applications run on Intel's EM64T?

    Many applications were developed prior to the introduction of Intel's Extended Memory 64 Technology. 32-bit applications should run at full performance though this can not be guaranteed. To ensure a smooth transition, Microsoft ? offers a free 120 day trial of Windows XP Professional x64 Edition software. For more information, go to Windows XP Professional 64 Edition trial software program.

  • What value does Intel EM64T bring to personal workstations?

    Today's 32-bit operating systems limit users to 32-bits (4GB) of memory address space. This limits the type and amount of I/O (input/output) and physical, configurable memory. I/O cards with on-board memory (e.g. graphics) and the system memory both consume the same address space. When I/O cards with large memory are present, this leaves less addressable space, thus limiting the amount of physical memory one can effectively put in a system. Some examples can be shown where physical system memory is actually limited to less than 3GB.

    A 64-bit architecture will tremendously expand addressable memory space allowing the large I/O to work in harmony with physical memory.

  • Why has HP chosen to add Intel Extended Memory 64 Technology to their product line?

    HP constantly monitors the industry for, or invents, new technologies that could benefit our customers. EM64T is a new technology that has shown great promise in meeting our customers' needs. We've chosen to add this technology to our workstation product line to provide our customers increased flexibility when choosing their workstation solutions.

  • If I don't need 64-bit today, why would I consider moving to an HP Workstation enabled with a new Intel processor with EM64T?

    Intel EM64T is not a special architecture just for users with 64-bit addressing needs. This technology is the follow-on processor to today's existing Intel processor family. Buying an EM64T enabled workstation will provide the flexibility to move to a 64-bit operating system later on the same workstation, should your computing needs change.

  • What sets HP Workstations enabled with Intel EM64T apart from others' workstations?

    HP is leading the industry to industry-standard 64-bit computing.

    HP has been developing 64-bit systems and operating systems for 20+ years.

    HP has an understanding of customer needs, operating systems, applications, and hardware that is unmatched in the industry.

 Hyper-Threading*
  • What is Hyper-Threading technology*?

    Faster clock speeds are an important way to deliver more computing power, but clock speed is only half the story. The other route to higher performance is to accomplish more work on each clock cycle, and that's where Hyper-Threading technology comes in. Hyper-Threading technology enables the processor to utilize its execution resources more efficiently, delivering performance increases and improving user productivity. Hyper-Threading technology presents the Pentium 4 processor to modern operating systems and applications as two virtual processors that can work on two sets of chores simultaneously. The benefits of this technology include:

    • Support for multi-threaded code and multi-tasking operations through better utilization of processor resources.
    • Multiple threads/tasks running simultaneously to increase the number of transactions that can be executed.
    • Improved reaction and response times for end users.

    For more detailed information visit Intel's Hyper-Threading site at: www.intel.com/homepage/land/hyperthreading.htm

  • Is Hyper-Threading Technology available on all HP xw4300 systems?

    Not all systems. All single core Pentium 4 processors offered on the HP xw4300 will support Hyper-Threadingii. The dual-core processor(s) offered will have two true processors contained in one package already, eliminating the need for Hyper-Threading Technologyii.

  • Is Hyper-Threading Technology something I can turn "on" or "off?"

    Yes, HT is controlled from a simple setting in the BIOS. You can experiment with HT by testing your systems and applications with it turned "on" and turned "off" to see what works best for you. For convenience, HP also provides a preloaded applet that can turn HT on and off (followed by a simple reboot).

  • Does Hyper-Threading Technology improve performance in all situations?

    Not in all situations. Hyper-Threading Technologyii (HT Technology) is beneficial in many circumstances, but in some cases it can actually hurt the performance of the system. HT Technology is not compatible with older operating systems (Windows 2000, Windows 98, Windows NT, etc) and will actually cause systems running these legacy operating systems to run slower with HT turned on. However, with newer operating systems (Windows XP), the system can really take advantage of the Hyper-Threading Technologyii. HT can really improve system performance when multi-tasking (running several applications at once) or when running multi-threaded applications. Most workstation applications are multi-threaded to take advantage of multiple processors. As a result, Hyper-Threading technologyii plays very well into the technical computing environment.

  • What operating systems take advantage of Hyper-Threading Technology?

    Windows XP takes advantage of Hyper-Threading Technology. Some Linux distributions also support HT but not all of them. Older operating systems (Windows 2000, Windows NT, etc) will actually run slower with Hyper-Threading Technologyii turned on.

*Hyper-Threading (HT) Technology requires a computer system with an Intel Pentium processor supporting HT Technology and an HT Technology enabled chipset, BIOS, and operating system. Performance will vary depending on the specific hardware and software you use. See http://www.intel.com/info/hyperthreading/ for more information including details on which processors support HT Technology.

 PCI Express Graphics and I/O
  • What is meant by PCI Express?

    PCI Express is the latest generation of PCI architecture. PCI Express is a radically new implementation of the PCI computer bus that uses existing PCI programming concepts and communications standards, but is based on a much faster serial communications system.

  • What's the advantage of PCI Express for graphics? What are the differences?

    PCI Express is the next generation interface not only for graphics cards, but also for I/O cards. PCI Express is a scalable interface, and depending on the chipset the system can have multiple PCI Express connections with various bandwidths. For graphics cards, the defined standard is "by sixteen" (or x16). This implementation of PCI Express provides twice the unidirectional bandwidth and four times the peak bandwidth as AGP 8X. The PCI Express specification also allows for 75W from the motherboard to the graphics cards. This is three times as much power as the standard AGP 8X specification.

  • Will the HP Workstations HP xw4300 support the AGP 8X graphics?

    No. The chipset in the HP xw4300 does not support the AGP interface. Instead, a new PCI Express (x16) graphics slot will be available. Graphics card vendors are launching a whole new line of graphics cards that will be compatible with the new PCI Express interface.

  • Will I be able to plug my AGP graphics cards into the HP xw4300?

    No. AGP and PCI Express are completely different interfaces. An AGP card will not plug into a PCI Express slot, nor will a PCI Express card plug into an AGP slot.

  • What graphics cards are available on the HP xw4300 Workstation?

    High-end 3D NVIDIA Quadro FX 3450 (PCIe), Quadro FX 4500 (PCIe)
    Mid-range 3D ATI V5100 (PCIe); NVIDIA Quadro FX 1400 (PCIe))
    Entry 3D ATI V3100 (PCIe); NVIDIA Quadro FX 540 (PCIe)
    Professional 2D NVIDIA Quadro NVS 285 with NVIDIA TurboCache technology (PCIe)


 ISV Certifications
  • What is the ISV Certification plan for the HP xw4300 Workstation?

    HP has very strong relationships with independent software vendors (ISVs). The software vendors recognize that HP is a critical ally in the industry, not only as a hardware OEM, but in marketing and support relationships. HP, in many cases, has engineering personnel located full-time on site at these software vendors' location providing technical support, application performance tuning, and graphics driver optimization.

    ISV certification is a critical aspect of the workstation value proposition. Workstation customers are running very complicated, high-end, technical applications and reliability and stability are an absolute requirement. The entry workstation is targeted at specific technical applications, many of which were listed above. The following table outlines the applications that are planned for the HP xw4300.

    Some of the applications listed in the table do not certify hardware, but they are listed as "targeted" applications. For those applications listed above that do offer hardware certification, the new entry workstation will be certified.

Red Hat Enterprise Linux WS 3 and the HP Installer Kit for Linux are also available.

    Due to licensing agreements, HP Workstations cannot support and do not load dual operating systems --- whether it be a Windows and Linux combination or a Windows 32-bit and Windows 64-bit combination.

 Microsoft Windows

  • Is Microsoft Windows 2000 supported on the HP xw4300 Workstation?

    No, but... Microsoft has stopped offering Windows 2000, and has stopped supporting it as of June 2005. Windows 2000 cannot be offered or fully supported with the HP xw4300. However, HP recognizes that many customers still need to deploy their own Windows 2000 licenses on new hardware. With this in mind, HP has performed limited testing on most of the components available on xw4300, and has documented issues found. A full summary of the testing, issues found, and support information can be found in this whitepaper. Drivers for Windows 2000 on xw4300 can be found at this location within HP's support website.

  • Is Microsoft Windows NT supported on the HP xw4300 Workstation?

    No. Microsoft has stopped offering and supporting Windows NT. Windows NT is not supported or offered with the xw4300. No drivers will be available for Windows NT.

 Linux

  • What is the HP Installer Kit for Linux?

    The HP Installer Kit for Linux facilitates the installation of the Linux operating system allowing you to make your own image, and to customize Linux to meet your needs. The HP Installer Kit for Linux for the HP xw4300 will contain the HP Driver CD for Red Hat Enterprise Linux WS 3 and 4 Box Sets.

  • Does the HP Installer Kit for Linux actually contain the Red Hat Box Sets?

    No, you must obtain the Red Hat Box Set of your choice.

    Red Hat requires that you purchase Red Hat Enterprise WS 3 or 4. It is available from HP as After Market Option (AMO) kits.

  • Why is HP supporting Linux on workstations?

  • Why would I run Linux on my client?it seems more like an ISP or compute server OS?

    In the server space, Linux has established itself as a robust and well performing operating system for Intel Xeon?/Pentium 4 based servers. These aspects of Linux for servers are highly leveraged into the desktop space. Linux offers a multitude of desktops, window managers, and Open Source-based applications and tools that may very well fit what you need now, and with the support, extensibility, and control you will need for the future. In the DCC, CAE, EDA and the emerging oil and gas markets, Client Linux is a proven solution.

    Linux on the desktop provides an industry standard solution on industry standard platforms providing choice and flexibility. Linux on the workstation today is a high quality solution for engineering and technical computing applications typically run on UNIX based workstations.

  • Why doesn't HP offer a dual boot with Windows and Linux?

    HP cannot offer dual boots due to licensing agreements.

  • What client functionality is available on Linux?

    Linux is moving in on the client desktop. Client Linux deployments are fueled by better security, easier management, improved ease of use, lower cost, and virus protection. Governments, developing countries, "task-focused solutions," and SMB are all beginning moves to a Linux desktop.

    All types of productivity solutions available on a Microsoft Windows desktop environment are available on the Linux desktop as well. The challenges are integration of Linux client's with Windows client in the IT infrastructure. These integration solutions are improving over time.

 64-bit Linux

  • What version of Red Hat Linux supports 64-bit?

    Red Hat Enterprise Linux WS3 (RHEL 3 WS) has both a 32-bit version and a 64-bit version. HP will preinstall the 64-bit version and will also support the 32 and 64-bit versions with a Driver CD in the HP Installer Kit for Linux.

  • Are there other 64-bit distributions of Linux that will work on the HP xw4300 Workstation?

    Yes, HP has tried other distributions on the HP Workstations. To see what has been fully certified, go to www.hp.com/linux and click on the "OS Supported and Certified Matrices".

  • Can I run 32-bit apps on a 64-bit Linux OS? How does this work?

    Yes, you can run 32-bit apps on 64-bit Linux OS as the runtime support (mainly shared libraries) for the application exists on the system. The Linux convention for having 32-bit libraries and 64-bit libraries on the same OS is to have companion library directories. The 32-bit libraries are in the conventional locations?. /lib, /usr/lib, /usr/X11R6/lib, etc whereas 64-bit libraries just append 64 to the directory name such as /lib64, /usr/lib64, and /usr/X11R6/lib64. This also includes 32-bit versions of the graphics libraries which HP has included from the graphics vendors.

  • What do I do if my 32-bit apps do not run due to missing shared libraries?

    You will need to get the library from Red Hat's 32-bit RHEL 3 distribution and put it on your system in the appropriate directory and report the missing library to Red Hat through their Red Hat Network subscription. This will help Red Hat to get the right set of 32-bit libraries needed for most apps in future releases.

  • How do I install the 64-bit version of Linux?

    They will need to purchase the Red Hat Enterprise Linux 32-bits, either from HP or from some other source, and go through the normal Red Hat Anaconda install. Once they have completed the installation and are rebooting for the first time, the FirstBoot utility will run and ask if them if they have additional CDs to install. They will then insert the HP Driver CD for RHEL 3 and say "Yes." This process will install RHEL 3, any HP additions, and the accelerated graphics driver from the appropriate graphics vendors.

  • Once I have installed the 64-bit version of Linux, what do I have to do to build 64-bit apps?

    Simple. Just rebuild from scratch and the compiler will build 64-bit by default. This is true for most apps. However, some apps must be made 64-bit clean which means that the developers must review the code to get rid of any assumptions about 32-bitness, such pointer arithmetic issues. Some makefiles that explicitly declare paths such as /lib, /usr/lib and /usr/X11R6/lib might need to be changed to append "64."

 Manageability
  • What manageability features are available on HP personal workstations *?
