Correcting Flat-Panel Display Video Problems During
Microsoft Windows Server 2003 Operating System
Installations
NOTE:
The following information applies only to Microsoft Windows Server 2003 operating system
installations on systems that have certain flat-panel displays attached, and console redirection is
enabled in the System Setup program (console redirection is disabled by default). Systems that have a
CRT monitor attached, or systems that are having any other operating system installed, are not affected.
Under certain conditions, the image on some flat-panel displays may roll during the installation of
the Microsoft Windows Server 2003 operating system. This is caused by console redirection being
enabled in the System Setup program (console redirection is disabled by default).
Console redirection is intended for system management from a terminal attached to the system’s
serial port. When Windows Server 2003 detects that console redirection is enabled, it optimizes its
installation screens to a low-resolution text mode for a vt100-compatible terminal. Some flat-panel
displays cannot synchronize to that mode.
To correct the problem, restart the system, enter the System Setup program, and disable console
redirection. After installing the Windows Server 2003 operating system, enter the System Setup
program, and enable console redirection, if desired.
Maintaining Proper Back-Panel Ventilation
The back panel of your system provides airflow vents to maintain proper ventilation to the inside
of your system. Never place labels or other obstacles over an airflow vent.
Failure to Load usb-ohci Driver Message on Systems Running
Red Hat Enterprise Linux (Version 2.1)
A failure message may be displayed when
Initializing USB controller (usb-ohci)
appears during startup. Update versions of Red Hat Enterprise Linux (version 2.1) prior to Update
4 mistakenly attempt to load this driver for the USB 2.0 controller. Red Hat Enterprise Linux
(version 2.1) does not support USB 2.0. To avoid this erroneous message on versions prior to
Update 4, remove the line in
/etc/modules.conf that causes usb-ohci to load. Otherwise, install
Red Hat Enterprise Linux (version 2.1) Update 4 to resolve the problem.
Single Memory Module Installation
If only one memory module is installed, it must be installed in socket DIMM1_A or DIMM1_B.
Two-way interleaving is not supported for this configuration. See the
Installation and
Troubleshooting Guide for more information about memory modules.
