Abstract: NETFINITY 5500: with 256MB REGISTER SDRAM


SYMPTOM:

Netfinity 5500 intermittent memory failure during POST (Power On Self-Test). Depending on memory configuration, the failure occurs with various symptoms:


PROBLEM ISOLATION AIDS:


FIX:

  1.  As a workaround, place the DIMM with Header Code J1542 to a  memory slot other than J1. Or,
  2.  For a permanent fix, upgrade system BIOS to BIOS Level 3.  The BIOS is available in the following IBM website with  filename 36L9816.EXE:

    http://www.pc.ibm.com/us/files.html

     To download:

     The files are self-extracting executable files that will  prompt for a diskette.

     The corresponding Text files are viewable and may be printed.

  3.  Do not replace the DIMM, unless a solid memory failure is  detected outside the scope of this Tip.


NOTE: 256MB DIMMs with any other header codes are not suspect.
