**AMD 640/645     (Pentium Based on VIA VT82C590) [some info]      c97
640=VT82C595
645=VT82C586B

The  Shuttle  HOT-603 is  the  only  known  motherboard with  the  640
chipset.

There may be another version known  as the 640AGP with AGP support. It
is difficult to determine if this ever existed.

Various sources  state the  AMD 640  is the same  as the  VIA VT82C590
(VP2) chip set. However no first-hand source (datasheet, etc) has been
found. YMMV
