Known Issues With Running Windows Nt 4.0 And Windows 98 Second Edition - HP Compaq dc7100 DT Supplementary Manual

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 (hot-
swapping). 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.
