Instead, motherboards that will support Tualatin (0.13 micron process Pentium III) were shown. This is the newly revised i815EP B step motherboard. Coppermine based Pentium IIIs support AGTL+ (1.5V) but Tualatin will require AGTL (1.2V). Currently, Intel i815/E/EP boards only support AGTL+ (1.5V) so a revision was necessary. While it doesn't really look any different from the A step motherboards, the B step boards will support both Coppermine and Tualatin Pentium IIIs. This is good news for early adopters who will have an easy upgrade path. Here are pictures of the i815EP B step from Intel, FIC, Abit, and Gigabyte. A Q2 (May 15) release is planned for these boards. Intel's PDF announcing the i815's design change to the B step is here.
Although EPoX was the first to announce a dual i815 motherboard at last year's World PC EXPO, the product never really materialized. Enter the ACorp 6A815ED. ACorp has not disclosed how they were able to get the i815 to support two processors but it is expected to sample from the end of this month to the beginning of next month. They hope for a retail release at the end of next month. In the meantime, pictures are here, here, and here.
Iwill was showing off a motherboard based on the i860 Colusa chipset supporting Foster/Xeon (server version of Pentium 4). It will use two PGA602 sockets. Clearly, this is a different socket from the Pentium 4 (Willamette). Thanks to Firestone for mailing the link.
