**82378       System I/O (SIO) (82378IB and 82378ZB)           c:Mar93
***Notes:...
***Info:...
***Versions:
82378IB   c:mar93  (Only supports 2 PCI Bus Masters)
82378ZB   c:dec93  (Supports 4 PCI Bus Masters)
82378ZB   c:dec94  (Supports 6 PCI Bus Masters)

Don't know how to tell the difference between the last 2.

For some more (important) details see the Configurations section of
the 82430LX section, and the errata document below:

****Errata:2 (Aug'93)
82378IB to 82378ZB
Errata Fix and Feature Enhancement
Conversion FOL933002-01

1. Name of Change
   82378IB  to  82378ZB errata  fix,  feature  enhancement and  vendor
   proliferation

2. Description of Change
   The  82378ZB eliminates  all 82378IB  B-0 step  errata.  A complete
   listing of the 82378IB errata  may be found in the attached CDC/SIO
   B-0 Stepping Information document. In addition to the errata fixes,
   the  82378ZB  integrates  the  Interrupt Steering  logic  which  is
   required  for  systems  to   be  PCI  compliant.  This  integration
   eliminates  an external PLD  from the  motherboard and  reduces the
   system's total cost by approximately $2.

   The  82378ZB provides  several  feature enhancements  to the  82420
   PCIset.  These enhancements including  supporting four  PCI masters
   and adding power management features such as System Management Mode
   (SMM). The B-0 parts only  supports two PCI masters and contains no
   power management features.

   Finally,  the 82378ZB  will  proliferate from  LSI  logic to  Tosh-
   iba. This proliferation will result in two changes:
      1.  The leadframe will change from Copper to Alloy 42.
      2.  The manufacturing process will change from 1.0 u to 0.8 u.

3. Reason for Change

   The 82378ZB  eliminates all errata associated with  the 82378IB and
   provides new  functionality to the 82420 PCIset.   In addition, the
   vendor  proliferation   to  Toshiba  will   help  maintain  product
   availability to customers.  

4. Products Affected
   The 82378IB is the only product affected by these changes.
   
5. Qualification/Certification Plan
   82378IB  quality and  reliability  results will  be substituted  to
   achieve Level II  for the new components. The  results are enclosed
   in  the  attached 82420  &  82430  PCIset  Quality and  Reliability
   report.  

6. Timing
   The 82378ZB  will begin sampling  in September, 1993.  Sample parts
   will be marked  82378ZB Q184 while production units  will be marked
   82378ZB. The  82378ZB components may be ordered  through your local
   Field Sales Office.

Limited  production quantities for  the 82378ZB  will be  available in
Dec.  '93  and full  production  will  be  available in  January.  All
customers are asked to convert by February, 1994. Intel will phase out
B-0 material during the conversion period.
