  4.   ************************ and ***********************
  5.  system board FRU part number must be P/N 85F0077 or   P/N 92F0108.


NOTE:
Systems with serial numbers or system board FRU part numbers that are not listed above are not exposed to this problem and are not eligible for this ECA:.

DETAIL:
A limited number of 8535 and 8540 systems may experience one or more of the following failures:

  1.  Failure to RIPL with an OEM Network card.
  2.  When an OEM video adapter is installed, the monitor attached  to the video adapter may display unintelligible video patterns  or remain completely blank.
  3.  Various keyboard related failures that are not resolved with  a keyboard replacement.

In all three cases above, if the system unit meets all of the requirements called out in the "physical check" section of this ECA:, the system board will be replaced free of charge.

Alternate method to determine affected systems without removing the system cover is as follows:

determine system BIOS date:
- at the c:> type "BASIC" and press "ENTER".
- at the "OK" type the following line exactly as shown.
def seg=-1:for x=5 to 12:print CHR$(PEEK(x));:next
- press "ENTER"
- the system will display a date.
- if "Syntax Error" is displayed instead of a date, verify that
the line was typed exactly as shown above. (there may be a
problem in that your system may show the fourth letter of the
word CHR$ as a different letter depending upon the language.
please use this as the normal character string)
- if the date displayed is 9/25/1991 or later, no action is
required, the system is not eligible for this ECA:.
- if the date displayed is 9/24/1991 or earlier, the system
is eligible for this ECA:.
- to return to the c:>, type "SYSTEM" and press "ENTER".
