In order to incorporate speed enhancements for Yonah Based Processors, Intel
is converting the Intel® Core™ Duo Processors T2600, T2500, T2400 from C-0
Stepping to D-0 Stepping.

  • A BIOS update is required for D0-Step Products.
  • The D-0 stepping is backwards compatible with the C-0 stepping.
  • All C-0 products supported under Intel’s Stable Image Platform Program (ISIPP)
    will continue to be supported on D-0 stepping.
  • To improve package quality, D0-Stepping products use a package with
    Reverse Geometry Caps. The visible package differences are cosmetic only.

Intel plans to conduct conversion of Intel® Core™ Duo Processors, Intel®
Core™ Solo Processors and Intel® Celeron® M 400 series C0 processors over three
phases.
