WinDVD
™
Incompatibility Issue with Intel® CPU’s
September 20, 2002, document version 1.2
Introduction
InterVideo® WinDVD™
is the preferred DVD movie player for use on the IBM ThinkPad. Due to an
incompatibility issue with the previous release of the InterVideo WinDVD application and Intel’s latest
CPU revision, some users may find that the WinDVD application is unable to play DVD mo vies, and may
cause a system crash when they attempt to play a movie.
InterVideo has designed the WinDVD application to be portable and useable by many different system
manufacturers. The cause of this failure is due to a legacy CPU detection method in the WinDVD player
which will cause the DVD player to incorrectly identify the Intel® CPU as an AMD® CPU. This failure is
only exposed on the latest revision of Intel CPU’s.
Beginning 4Q 2002 Intel will begin shipping new revisions of the
Mobile Intel® Pentium®
4
Processor-
M
and the
Mobile Intel® Celeron® Processor
. The revision changes have been designed to have no
impact to end-users. However, a legacy CPU detection scheme utilized in previous release of the
InterVideo WinDVD player will incorrectly identify the new revision of the Intel CPU as an AMD
processor. This incorrect detection will cause a general protection fault when the WinDVD application is
used.
This document describes the failure condition, ThinkPad systems affected by the change, and the impact of
the failing scenario.
Scope
IBM ThinkPad Models Affected
Intel Corporation has released new revisions for the
Mobile Intel® Pentium®
4
Processor-M
and the
Mobile Intel® Celeron® Processor
. Pentium 4 Processor-M revisions are affected on the 1.6GHz,
1.7GHz, 1.8GHz, 1.9GHz, and 2.0GHz speeds. Intel Celeron Processor revisions are affected on the
1.4GHz and 1.5GHz speeds. These processors will be shifted from the current step level of B0 to the new
step level of C1.
The CPU revision changes will be rolled into the following ThinkPad systems starting October, 2002:
A-series: A31 systems with model number: 2652-xxx, 2653-xxx, 2654-xxx
R-series: R32 systems with model number: 2658-xxx, 2659-xxx, 2677-xxx
T-series: T30 systems with model number: 2366-xxx, 2367-xxx
No other ThinkPad systems are affected by the change.
To determine if you have a C1 revision CPU, you can obtain one of the CPU information utilities available
from
www.intel.com
.
