     Update patch file for processor 0683

     This BIOS update addresses Intel Errata G85 and E76.  This Errata 
        effects 933 MHZ / 1GHZ 'B' Stepping Level Pentium III processors, only. 
        (i.e. A and C Stepping Levels are okay, as well as B levels at speeds 
        lower than 933MHZ.)

     This BIOS includes a patch from Intel which Intel believes prevents a
        potential data error problem.  Although Intel states that the problem
        can only occur under certain limited temperature and voltage conditions, 
        IBM strongly recommends updating your BIOS immediately.

     For those customers who wish to use the new processor patch code 
        without updating their current level of BIOS, please refer to the
        "README.1ST" file.

PLKT42A/PLJT42A:
     Set "32-Clock Retry Enable" bit on in the ICH.

PLKT43A/PLJT43A:
     Fix for 103 POST error

PLKT44A/PLJT44A:
     SMBIOS: Fix memory device mapped address structure
