Description
The C1 step has not been shown to cause any other erroneous behavior aside from the InterVideo failure
noted above. The failure is caused by a legacy CPU detection algorithm in older versions of the InterVideo
application.
For a user who has a system already loaded with InterVideo 3.2-41.142 or earlier, an upgrade patch version
is available at: http://www.pc.ibm.com/qtechinfo/MIGR-44474.html. NOTE: any system manufactured
after October, 2002 will be loaded with an updated preload which contains the new InterVideo player. (See
appendix C. for a list of changes to the preload).
End-user:
If you have a system with the Intel C1 step CPU, have InterVideo 3.2-41.142 or earlier installed, and are
unable to download the update from the web, please contact the IBM Helpdesk at 1-800-772-2227.
Enterprise:
Beginning September, 2002 some ThinkPad systems will begin shipping with the new C1 stepping CPU.
For customers who have a DVD or DVD/CD-RW combo drive and use the InterVideo WinDVD player,
the system image will need to be updated to incorporate WinDVD version 3.2-41.148, 3.2-B041.148 or
later.
The fix version WinDVD player is available on the web for A31, T30, and X30 systems. The updated
player can be downloaded from: http://www.pc.ibm.com/qtechinfo/MIGR-42309.html (26MB). An updated
player for use with the R32 system will be available on the web at a future date. When the download
becomes available, this document will be updated with the download location.
Conclusion
Limited exposure
For customers using the IBM Preload, only those customers who have purchased one of the affected model
types, have a DVD or CD-RW/DVD combo drive, and use an old version of the InterVideo WinDVD
player to view DVD movies will notice any impact. No other preloaded applications or operating system
component will be affected.
All ThinkPad systems shipped from IBM with the C1 step CPU will have a fixed version of the WinDVD
application loaded in the preload. No adverse behavior will be noted on this system when used in
conjunction with the latest release of the WinDVD player.
All other users who have an impact to their WinDVD player can download a fixed version of the WinDVD
player from: http://www.pc.ibm.com/qtechinfo/MIGR-42309.html.
