**82430NX     PCIset (Pentium) NX (Neptune) (82433NX/82434NX)    Mar94
***Notes:...
***Info:...
***Configurations:
Parts:
Intel 82434NX (PCMC) PCI/CACHE/MEMORY CONTROLLER
Intel 82433NX (LBX)  LOCAL BUS ACCELERATOR

ISA (single CPU):	
82434NX + 2x 82433NX + 82378IB   
82434NX + 2x 82433NX + 82378ZB 

  The main difference between the 82378IB and 82378ZB is the number of
  PCI  masters supported.  See  the 82378  section  for details.   The
  pairing with the IB variant is  unlikely as it was outdated when the
  430NX was introduced.

ISA (Dual CPU):
82434NX + 2x 82433NX + 82379AB   

EISA: 
Intel 82434NX + 2x 82433NX + 82374EB + 82375EB 
Intel 82434NX + 2x 82433NX + 82374SB + 82375SB

  The main  difference between the EB  and SB variants is  that the SB
  includes  power  management  options.  It was  released  later  when
  various  enhancements had  been made  to  the EB  variant.  See  the
  82374/82375 section  for details. It  is unlikely the EB  variant is
  paired with  this chipset  as it  was replaced by  the SB,  when the
  430NX was being introduced.

These chipsets  are often paired with  the SMC 665 for  I/O support or
the NCR 810 for SCSI.
 
According to a Usenet post in comp.sys.ibm.pc.hardware.chips from '94,
there are at  least 2 revisions of this chipset.   The latter resolves
some issues with posted buffered writes.
