Introduction
Device drivers are required for proper functioning of devices included with computers. Some device driver support
is included with the operating system; however, newer devices frequently require additional device drivers that were
not available when the operating system was introduced. HP packages device drivers in Softpaq format and places
them on an HP Web site for the customers' convenience.
The Intel 915 Express chipset is known by the Intel code name “Grantsdale” and features PCI Express, DDR1 or
DDR2 memory support, support for up to four SATA storage devices, and the next generation Intel integrated
graphics. For more details refer to the Intel Web site.
For this paper, the 2004 HP Compaq Business Desktop Computers with the Intel 915 Chipset include these specific
models:
• HP Compaq Business Desktop dx6100 microtower
• HP Compaq Business Desktop dx6100 slim tower
• HP Compaq Business Desktop dc7100 convertible minitower
• HP Compaq Business Desktop dc7100 small form factor

Acronyms used
• 48-Bit LBA – Logical block Addressing. 28-bit LBA allows the use of hard drives up to 137 GB. 48-bit LBA
allows the use of hard drives significantly over 137 GB. For more information see
http://support.microsoft.com/default.aspx?scid=kb;en-us;303013
http://support.microsoft.com/default.aspx?scid=kb;EN-US;305098
• APM/APCI – APM (Advanced Power Management) is a legacy power management scheme that was first widely
supported in Microsoft® Windows® 95. Most of the interesting functionality for APM is in a machine-specific
BIOS that is hidden from the operating system. APM is a legacy solution that has been superseded by ACPI
(Advanced Configuration and Power Interface), which is the robust scheme for power management and system
configuration supported in the Windows 98 and Windows 2000 family of operating systems. Windows XP uses
ACPI. For more information see:
http://www.microsoft.com/whdc/archive/apm.mspx
http://www.microsoft.com/whdc/archive/w2apm.mspx
• APIC – an advanced programmable interrupt controller (APIC) scheme used by all PCs currently in production. It
consists of a local APIC which delivers interrupts to a specific processor and an I/O APIC which collects interrupt
signals from I/O devices and sends messages to the local APICs when those devices need to interrupt. Each I/O
APIC has an arbitrary number (typically 24) of interrupt inputs. For more information see:
http://www.microsoft.com/whdc/system/sysperf/IO-APIC.mspx
http://www.microsoft.com/whdc/system/sysperf/apic.mspx
• BIOS – Basic Input/Output System: The system’s firmware which allows the power up of various devices during
boot for the OS to load properly.
• HP – means that these device drivers are available from the HP Web site:
http://h18007.www1.hp.com/support/files/index.html
• HP/WU – means that drivers are available from both the HP Web site (Softpaq) and from Windows Update. HP
has tested and validated that the device drivers on the HP Web site function as expected with the operating
systems that are listed as supported in Table 3 Operating System Support Definitions.
• HPQFlash – HPQFlash is a BIOS update utility used from within Windows from Hewlett-Packard that updates the
read-only-memory (ROM) chip on the system board.
• N/R – means "not recommended."
• OS – means that support is included with the operating system.
• PIC – A programmable interrupt controller (PIC) scheme first used in the IBM PC/AT from the 1980s that used two
Intel 8259 programmable interrupt controllers. Each 8259 had eight interrupt inputs (IRQs). The second interrupt
controller was connected to the first interrupt controller leaving fifteen interrupt inputs available for all devices in a
PC.
• ROMPAQ – ROMPAQ is a BIOS update utility on a bootable diskette from Compaq (now Hewlett-Packard) that
updates the read-only-memory (ROM) chip on the system board.
• SP – Service Pack
• 98SE – refers to Microsoft Windows 98 Second Edition
• Me – refers to Microsoft Windows Millennium Edition
• NT4 – refers to Microsoft Windows NT 4.0
• 2000 – refers to Microsoft Windows 2000 Professional

• Hyper-Threading makes a single physical Hyper-Thread enabled Pentium 4 processor appear as two logical
processors to the operating system.
• Due to application compatibility concerns, HP recommends Windows XP -SP1 or later be used when
Hyper-Threading is enabled. Some Linux versions also support Hyper-Thread.
• Windows 2000 supports up to two processors. Business Desktops do not support 2 processors.
• Optimizations for Hyper-Threading are not included in Windows 2000 Professional so performance will be lower
with Hyper-Threading enabled.
• Support for Hyper-Threading is available for both Windows XP Professional and Windows XP Home Edition.
Some Linux versions also support Hyper-Thread.
• Windows XP Home Edition provides support for one physical processor.
• Windows XP Professional provides support for one or two physical processors.

Known issues with running Windows NT 4.0 and Windows 98
Second Edition
Windows NT 4.0 and Windows 98 Second Edition have been loaded and tested with "will it run" criteria. No
driver development will be undertaken by HP. Many subsystems will not function when a device driver is not
available. Problems are documented with customer advisories as appropriate. No integration testing is performed.
HP does not provide phone and e-mail support.
1) While running Microsoft Windows 98 Second Edition and Microsoft Windows NT 4.0 on 2004 HP
Business Desktop Computers with the Intel 915 Chipset, the following subsystems will not function since
device drivers are not available from either HP or Microsoft: audio, graphics, NIC, wireless LAN, modem,
PC card, HP ProtectTools Embedded Security (TCPA TPM), USB 2.0, networking, and Multibay (hotswapping). While running Microsoft Windows NT 4.0 on 2004 HP Business Desktop Computers with the
Intel 915 Chipset, the following subsystems also do not have available device drivers so these subsystems
will not work: USB 1.X, IEEE 1394, ACPI, and Bluetooth. Support is also not built into Windows NT4.0 and
Windows 98 Second Edition for CD-RW burning and disk drive support for disk drives larger than 137 GB.
To get higher resolutions, higher color depths, or accelerated performance, a third-party add-in PCI
graphics card must be added while running Windows NT4.0 or Windows 98 Second Edition. HP does not
provide support for third-party add-in cards.
While running Windows 2000 or Windows XP, the 2004 HP Compaq Business Desktop Computers with
the Intel 915 Chipset support two parallel ATA (PATA) devices and four serial ATA (SATA) devices. The
2004 HP Compaq Business Desktop Computers with the Intel 915 Chipset ship with a SATA hard drive and
with one or two PATA optical drives.
Users attempting to boot to the hard drive or OS installation CDs with Windows NT4.0 (the original version
through Service Pack 5; Service Pack 6 is not impacted by this issue) will observe their systems either reboot
or experience a blue screen error message (STOP 0x3E) during the initial text-based setup. Microsoft
Windows NT 4.0 does not comprehend the latest Intel processors which are hyper-threading capable.
Windows NT 4.0 believes that the system has dual, mis-matched processors. To work around this issue,
change the “Limit CPUID Maximum Value to 3” BIOS setting option to enabled.
While running another operating system (e.g. Windows 98 SE, Windows Me, Windows NT, and Linux),
the BIOS must be configured to use the non-default setting of Combined IDE Controller for compatibility
mode which supports two PATA devices and two SATA devices. HP also recommends the other two BIOS
setup options while running Windows 98 SE, Windows Me, Windows NT, and Linux:
a) Set Storage > Storage Options > SATA Emulation to Combined IDE Controller.
b) Set Advanced > Power-On Options > Hyper-Threading to Disable.
c) Set Advanced > Power-On Options > ACPI/USB Buffers at Top of Memory to
Disable.
d) Set Advanced -> Power-On Options -> Limit CPUID Maximum Value to 3 to Enable
2) Users may experience hangs or reboots after installing the Intel chipset support package for Windows 98
Second Edition if other device drivers were loaded first, e.g. NIC, audio, or graphics. To work around the
issue:
a) In F10 (BIOS) Setup Advanced > PCI Devices, change the first two USB controllers (2658 and
2659) to Disabled.
b) Save changes, exit, and reboot.
c) Run the chipset support package setup.
d) Reboot the system.
12
Page 13
e) Allow devices to enumerate.
f) Reboot as required.
g) Make sure all devices are finished enumerating.
h) Reboot, re-enter F10 Setup, and change the first two USB controllers back to their original IRQs (10
and 11). Alternatively, user can save default settings and exit.
The user should no longer see any issues once this initial enumeration is complete.
