Servers - ECA 003: MCA Servers 8595 / 9595 / 8641 Pentium processor replacement

Applicable to: World-Wide

Abstract:
ECA003, 9595/8641 PENTIUM PROCESSOR REPLACEMENT

PURPOSE:
THE PURPOSE OF THIS ECA IS TO PROVIDE A REPLACEMENT INTEL PENTIUM PROCESSOR MODULE FOR SERVERS 95, 500, 8590/8595 AND 9590/9595 SYSTEMS WITH PENTIUM 60, 66 AND 90 MHZ PROCESSORS. THE REPLACEMENT MODULE RESOLVES THE "FLOATING POINT" CALCULATION PROBLEM.

This ECA will expire July, 2001.

THIS ECA WAS PREVIOUSLY IMPLEMENTED BY REPLACEMENT OF THE ENTIRE PROCESSOR BOARD WHICH WAS SENT DIRECTLY TO THE CUSTOMER. THE NEW PROCEDURE OBSOLETES THAT METHOD BY MAKING THE FOLLOWING CHANGES:

1. ALL PARTS WILL BE PROVIDED BY THE SERVICER USING ROUTINE FRU PARTS ORDERING PROCEDURES.

2. ON SYSTEMS WITH 60 AND 66 MHZ PENTIUM PROCESSORS, ONLY THE PENTIUM MODULE (HEATSINK ATTACHED) WILL BE REPLACED.

BY REPLACING ONLY THE INTEL MODULE, THE EXISTING BIOS LEVEL INSTALLED ON THE CUSTOMER'S SYSTEM WILL REMAIN UNCHANGED. THIS ELIMINATES THE EXPOSURE TO POSSIBLE BIOS / OPERATING SYSTEM CONFLICTS WHICH COULD OCCUR IF THE BIOS LEVEL OF THE REPLACEMENT FRU IS DIFFERENT THAN THE BIOS LEVEL ON THE CUSTOMER'S ORIGINAL PROCESSOR BOARD.

3. ON SYSTEMS WITH 90 MHZ PENTIUM PROCESSORS (SERVER 500, AND UPGRADED SERVER 95's), REPLACEMENT OF THE ENTIRE PROCESSOR BOARD WILL CONTINUE, HOWEVER IT WILL NOW BE DELIVERED BY THE SERVICER, BY ORDERING FRU P/N06H7095 AND WILL HAVE BIOS LEVEL 5 INSTALLED.

<<<<<<<<<<<<<<<<<<<<<< WARNING >>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>
>>>>>>>>>> IMPORTANT NOTE FOR 90 MHZ SYSTEMS <<<<<<<<<<<<<<<

THE EXISTING BIOS VERSION INSTALLED ON THE CUSTOMER'S SYSTEM MAY BE AT A DIFFERENT LEVEL THAN WHAT IS INSTALLED ON THE REPLACEMENT PROCESSOR BOARD. POSSIBLE BIOS/OPERATING SYSTEM CONFLICTS MAY OCCUR IF THE BIOS LEVEL INSTALLED ON THE REPLACEMENT PROCESSOR BOARD (CURRENTLY AT LEVEL 5) IS DIFFERENT. REFER TO RETAIN RECORD H126229 FOR IMPORTANT DETAILS CONCERNING BIOS LEVELS.

TWO SPECIAL ECA PROCESSOR KITS ARE NOW AVAILABLE FROM MECHANICSBURG TO BE USED FOR THIS ECA ONLY:

P/N07H0758 PROVIDES A 60 MHZ PENTIUM PROCESSOR MODULE KIT.
P/N07H0759 PROVIDES A 66 MHZ PENTIUM PROCESSOR MODULE KIT.

PHYSICAL CHECK:
SERVER SYSTEMS LISTED ABOVE HAVE BEEN MANUFACTURED WITH THE DEFECTIVE PENTIUM PROCESSOR. TO VERIFY THAT A PROCESSOR IS AFFECTED, A PROCESSOR TEST PROGRAM HAS BEEN MADE AVAILABLE BY IBM. THIS BOOTABLE PROGRAM WILL DISPLAY PROCESSOR ID INFORMATION AND TEST THE PROCESSOR'S FLOATING POINT DIVISION FUNCTION. THE TEST RESULTS WILL BE DISPLAYED TO THE USER, AND CLEARLY IDENTIFY IF THE PROCESSOR HAS THE FLOATING POINT DIVIDE (FDIV) DEFECT.

THE PROCESSOR ID PROGRAM MAY BE OBTAINED THROUGH THE IBM INTERNAL "VALUE" DISK BY ENTERING THE FOLLOWING COMMAND AT THE VM PROFS/OFFICEVISION COMMAND LINE:

REQUEST CPUIDIBM PACKAGE FROM VALUE AT BCRVMPC2

THE ID PROGRAM MAY ALSO BE OBTAINED FROM THE IBM PC COMPANY BULLETIN BOARD SERVICE BY CALLING 919-517-0001 AND DOWNLOADING THE FILE TITLED "CPUIDIBM.DSK".

A COPY OF THE PROGRAM ON DISKETTE MAY BE REQUESTED FROM THE IBM PC COMPANY HELPCENTER BY CALLING 1-800-426-3389 IF THE TWO METHODS ABOVE ARE NOT AVAILABLE.

INTEL 386 AND 486 PROCESSORS ARE NOT AFFECTED.

SYSTEM DIAGNOSTICS COMPLETE WITHOUT ERRORS.

PREREQUISITES: NONE

COMPANION: NONE

CONCURRENT: NONE

DETAIL:
PHONE CALLS FROM CUSTOMERS REQUESTING THIS ECA WILL BE DIRECTED TO IBM DISPATCH. THE SERVICER SHOULD THEN CONTACT THE CUSTOMER, DETERMINE THE REQUIRED ECA PART AND ORDER IT USING NORMAL PROCEDURES.

INCLUDED WITH THE NEW 60 AND 66 MHZ PROCESSOR MODULE FRU KITS:

COMPLETE INSTALLATION INSTRUCTIONS,
A SPECIAL MODULE REMOVAL TOOL,
A MODULE INSERTION PAD TO PREVENT PROCESSOR BOARD DAMAGE,
THE PENTIUM MODULE WITH HEAT SINK ATTACHED.

THE 90 MHZ PROCESSOR BOARD ASSY IS FRU P/N06H7095.

NOTES:
ALL PARTS REMOVED, PENTIUM MODULES AND PROCESSOR BOARDS, ARE TO BE RETURNED TO IBM IMMEDIATELY FOLLOWING THE INSTALLATION USING NORMAL UPR PARTS RETURN PROCEDURES.

THE USE OF THE SPECIAL ECA 60 AND 66 MHZ PENTIUM PROCESSOR MODULE KITS (P/N's 07H0758 AND 07H0759) FOR ANY SERVICE ACTION EXCEPT THIS ECA IS NOT SUPPORTED BY ENGINEERING. THEREFORE, USE OF THESE SPECIAL PARTS WILL NOT BE RECOGNIZED, OR REIMBURSED, AS A NORMAL WARRANTY PART FOR ANY OTHER SERVICE ACTION (SERVICE CODE O1, etc.).

PART, TRAVEL AND LABOR FOR THIS ECA SHOULD BE RECORDED USING SERVICE CODE 33, ECA003 AND OTHER OFFICE WORKED 990.

This ECA will expire July 27, 2001.

ADDITIONAL INFORMATION ABOUT BIOS LEVEL 3.00 AND OTHER BIOS LEVELS IS AVAILABLE IN RETAIN RECORD H126229.

PENTIUM IS A TRADEMARK OF INTEL CORPORATION

ADDENDUM:
The versions of Flash/BIOS currently available for 9595 products with a Type 4 Reference Diskette are:


Version 1.00

Initially shipped with the 9595 models xNx, xPx and xQx.
Supports 16MB Memory SIMMs.

2.00

Identical to version 1.00, except support for 32MB Memory SIMMS
was added.

3.00

Support was added for the following enhancements:
a. 90MHZ processor card, FRU P/N06H3739, for 9595 &
8641.
b. CD-ROM as a bootable device.

Notes:
This version of BIOS REQUIRES the Reference Diskette to be at
version 1.31 and the Diagnostic Diskette be at version 2.31.

OS/2 2.0X requires later SCSI Device Drivers (IBM2SCSI.ADD) with this
version of flash BIOS.

4.00

This version was released, but immediately superseded by
version 5.00, which is the preferred replacement.

5.00

Note: Version 5.00 BIOS requires the Reference Diskette to be at
version 1.33 and the Diagnostic Diskette to be at version 2.32 or higher.

Support was added for the following enhancements:

a. Provides support for the 4 GB (gigabyte) hardfile.
b. Enables the VPD (Vital Product Data) to display the processor ID
and Step level (thereby, enabling a clear determination if a Pentium
processor with the floating point divide (FDIV) fix is installed.
c. Allows disabling of the error reporting log POST error which is useful
during RIPL under some conditions.

Resolves the following problems:

a. Corrects problems encountered with the bootable CD-ROM
attached to the RAID controller, when an additional non-RAID SCSI
adapter is installed.
b. Fixes diagnostic problems related to the CD-ROM being attached
to the RAID controller.
c. Fixes problems encountered while running SCSI fixed disk
diagnostics with the "read verify" option selected.



This Device Driver may be downloaded from the IBM PC Company Bulletin Board System by calling 919-517-0001.

Upgrading the POST/BIOS:

The Level of POST/BIOS is indicated on the IBM logo screen of the system.

Type 4 Reference Diskette versions below 1.31 will be disabled from running on a system with a BIOS version 3.00 to prevent configuration errors and startup sequence errors. If the system is "flashed" DOWN below BIOS version 3.00, AN OLDER REFERENCE DISKETTE WILL BE REQUIRED to configure the system.

Back up the system partition before updating the system and SAVE the diskettes. This set of back-up diskettes will be compatible with BIOS level 1, 2, 3 or 5.

Also verify configuration information and startup sequence before updating the system. A configuration error and startup sequence error will occur after the update. The new Reference diskette will be required to correct the configuration error.

Prior to "Flashing" a system to a different BIOS version, the customer's original System partition should be backed up to diskette and saved. This will allow restoration of the original system configuration (setup) in the event of an unforseen compatibility problem. However, the Flash/BIOS version can not be backed up from the system to a Diskette. Therefore, before "flashing" a system to a different version, it is recommended that the customer's current version BIOS diskette be available.

Additional information about BIOS level 3.00 is available in Retain record H126229.
