“The issue concerns the “Alviso” chip set, part of the Sonoma platform, which comprises the currently-shipping Pentium M processor, code-name Dothan; the Alviso chip set; and its latest wireless module. Sources said Intel will book the Alviso for revenue this year, and push the bulk of its shipments until early 2005. Intel will also launch the platform in early 2005.
