i believe that a-bit makes a dual pIII FPGA motherboard.  this would
eliminate the need for the bridges.

Subject: SLOT 1 <-> FC-PGA converter in DUAL-SMP systems


Dear Sirs.

We use with great success and with reliability TYAN's Thunder 2500
mainboard (2x 866MHz) for our server box. We wish to upgrade this
machine with to 1000 MHz Intel PIII CPUs within the next months.
As we know, this mainboard has two SLOT 1 for CPUs and the most
Intel-launched CPUs today are FC-PGA types. My first though was to
obtain high quality (but from whom?) Slot 1 to FC-PGA converters as
offered by several vendors but in the past I read much about high
frequency/impedance problems with CPUs in such converter boards,
especially for dual SMP systems.

Has anyone experiences with such converters in DUAL-SMP boxes and
CPUs >933 MHz? Can you name me please some high quality vendors of
such boards?

Thanks.

Oliver
