Notes:
1. Model numbers provided are worldwide generally available variant (GAV) model numbers which are
not orderable as listed and need to be modified by country. The U.S. GAV model numbers use the
following nomenclature: xxU. For example, the U.S. orderable part number for 7978-71Y is 7978-71
U. See
the product specific Official IBM announcement letter for other country-specific GAV model numbers.
GAV to MTM mapping for A.P. Geographies follow the same pattern. Substitute the last character with
the country-specific designator.
