Lenovo ThinkPad R61i - Manual (Page 19)

The installer compares the current version level against the minimum
version level. If the current level is greater than or equal to the minimum
level, the installer looks for a .tvt file with a compatibility code (for
example: AA, AB) that is equal to the minimum version compatibility
code and a level that is greater than the current version level (all other
version fields in the .tvt filename must match the minimum version
exactly). If it does not find a file, the install process continues without
updating the Predesktop Area. If the current level is less than the
minimum level, the installer will look for a .tvt file with a compatibility
code (AA or AB). that is equal to the minimum version compatibility code
and a level that is greater than or equal to the minimum version level (all
other version fields in the .tvt filename must match the minimum version
exactly). If a file is not found meeting these criteria, the installation is
halted.

v Predesktop Area language packs (approximately 5 – 30 MB each): There are
16 language packs for Windows PE that are supported in Rescue and
Recovery 4.21. Each language pack is named in the format
z652ZABXXXXCC00.tvt where XXXX is the build ID and CC represents the
language. One of these files is required if the Predesktop Area is being
installed on a non-English system or a system with a non-supported
language and must be in the same directory as the main installation and the
US Predesktop Area .tvt file. If the Predesktop Area is being installed or
updated and a language pack is required, the installation looks for the
minimum level of language pack required in a version file contained within
the installation executable. The installation also looks for a language pack .tvt
file that is greater than any current language pack that is already installed
and greater or equal than the minimum version required.
Following is a list of languages supported in Rescue and Recovery 4.21:
– Brazilian Portuguese
– Danish
– Dutch
– English
– Finnish
– French
– German
– Italian
– Japanese
– Korean
