Service Information:
                     Intel has developed Pentium OverDrive Processors that allow an Intel 486 based system to be upgraded with Pentium OverDrive
                     Technology:

 
                      Intel Product No.
                       -----------------
                                 PODP5V63  63Mhz Intel Pentium OverDrive Processor
                                 PODP5V83  83Mhz Intel Pentium OverDrive Processor

                     The following IBM Commercial Desktop Systems are compatible with the Pentium OverDrive Processor upgrades:

                     IBM PS/ValuePoint & PS/ValuePoint Performance Series

                     6382/S    6472    6492

                     6384/D    6482    6494

                     6387/T    6484    6381 (486DX models only)
 

                     IBM PC 300 Series

                     See NOTE 1 below

                     6571  6581

                     6573  6583
 

                     IBM PS/2

                     9576i  9576s

                     9577i  9577s
 
 

                     System Requirements:
                     Following are hardware and software prerequisites that MUST be met PRIOR to installing the Pentium OverDrive upgrade. Failure to
                     install the prerequisites WILL result in a non-functional system and/or damage to the Pentium OverDrive Processor.

                     1. Flash BIOS updates. ALL systems listed above require the latest level Flash BIOS to be installed. These Flash BIOS updates enable
                     the system to support the transition from Intel 486 technology to Intel Pentium technology.

                     - ValuePoint 6382, 6384, 6387
                     - ValuePoint 6381
                     - ValuePoint 64xx
                     - PC300
                     - PS/2 9576i, 9577i

                     2. Interposer adapter. The Interposer adapter is 235 pin socket adapter that is installed between the Pentium OverDrive Processor and
                     the processor socket on the system board.

                     See NOTE 2 below for information on obtaining an interposer adapter.

                     The following systems from the list above REQUIRE an interposer adapter:

                     PS/ValuePoint
                     See NOTE 3 below  IBM PC 300 Series      IBM PS/2
                          -------------   -----------------    -------------
                           6472  6492        6571   6581        9576i  9576s
                           6482  6494        6573   6583        9577i  9577s
                           6484
 

                     3. Check the User's Guide that ships with the system for information on installing upgrades in the OverDrive socket. Jumper changes
                     are required on some models when upgrading to an OverDrive Processor.

                     IBM PC Co Warranty Support:
                     Installation of this upgrade is considered a non-IBM modification of the system. Support for system or software related failures as a
                     result of installing the Intel Pentium OverDrive upgrade should be directed to the point of purchase or the manufacturer of the upgrade,
                     Intel.

                     The IBM PC Company will not reimburse IBM Authorized Servicers or Remarketers for the installation or maintenance of the Intel
                     Pentium OverDrive Processor or the interposer adapter. BIOS updates are customer installable.

                     Note:
                     1. IBM PC 300 Series PCI models may require additional configuration assistance. Contact the IBM PC Company HelpCenter for more
                     information.
                     2. The IBM PC Company HelpCenter will provide the interposer adapter on request as a courtesy to IBM customers free of charge.
                     System specific installation assistance will also be provided by the HelpCenter.
                     For Austria - Please contact your Dealer Support Group who will handle the supply.
                     3. IBM PS/ValuePoint 6381/Si, 6382/S, 6384/D and 6387/T systems DO NOT require an interposer.
                     4. OverDrive Processor and Pentium are trademarks of the Intel Corporation.
