IF THE SYSTEM UNIT MEETS ALL OF THE REQUIREMENTS CALLED OUT IN THE "PHYSICAL CHECK" SECTION OF THIS ECA, A REPLACEMENT SET OF SYSTEM ROM BIOS (FRU P/N92F2434) WILL BE PROVIDED AT NO CHARGE TO THE CUSTOMER.

PHYSICAL CHECK:
TO REQUIRE A ROM BIOS REPLACEMENT KIT, THE SYSTEM MUST MEET THE FOLLOWING REQUIREMENTS:

THE SYSTEM UNIT SERIAL NUMBER MUST FALL WITHIN THE FOLLOWING RANGES:
1. 8535 SYSTEMS-
  1. MODEL 8535-040
    1. SERIAL NUMBER 23-A0000 TO 23-M9999.
    2. SERIAL NUMBER 78-TXD00 TO 78-XPV99.
  2. MODEL 8535-043
    1. SERIAL NUMBER 23-AA000 TO 23-TC999.
    2. SERIAL NUMBER 78-AAAA0 TO 78-BLTG9.
  3. MODEL 8535-24X
    1. SERIAL NUMBER 23-TD000 TO 23-ZK999.
    2. SERIAL NUMBER 78-BLTH0 TO 78-CYKP9.
2. 8540 SYSTEMS-
  1. MODEL 8540-040
    1. SERIAL NUMBER 23-AA000 TO 23-NN999.
    2. SERIAL NUMBER 78-NM000 TO 78-PM999.
  2. MODEL 8540-043
    1. SERIAL NUMBER 23-AAA00 TO 23-LGX99.
    2. SERIAL NUMBER 78-YMKW0 TO 78-ZFFY9.
  3. MODEL 8540-0451.
    1. SERIAL NUMBER 23-AAAA0 TO 23-LYDX9.
    2. SERIAL NUMBER 78-XBX00 TO 78-YDG99.
OR
THE SYSTEM BIOS DATE MUST BE 09-24-91 OR EARLIER.
THE FOLLOWING PROCEDURE SHOULD BE USED TO DETERMINE SYSTEM BIOS DATE:
- AT THE C:> PROMPT TYPE "BASIC" AND PRESS "ENTER".
- AT THE "OK" TYPE THE FOLLOWING EXACTLY AS SHOWN: DEF SEG=-1:FOR X=5 TO 12:PRINT CHR$(PEEK(X));:NEXT
- IF "SYNTAX ERROR" IS DISPLAYED INSTEAD OF A DATE, VERIFY THE LINE WAS TYPED EXACTLY AS SHOWN ABOVE.
- IF THE DATE DISPLAYED IS 09-25-91 OR LATER, THE SYSTEM IS NOT ELIGIBLE FOR THIS ECA.
- IF THE DATE DISPLAYED IS 09-24-91 OR EARLIER, THE SYSTEM IS ELIGIBLE FOR THIS ECA IF REQUIREMENT 3 (BELOW) IS MET.
AND
SYSTEM BOARD FRU PART NUMBER MUST BE P/N92F0108 OR P/N85F0077
