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.
