IBM PC330/PC350 - ECA001 - IBM PC300 Series Pentium processor replacement

Applicable to: World-Wide

PURPOSE:
THE PURPOSE OF THIS ECA IS TO PROVIDE A REPLACEMENT INTEL 60MHZ PENTIUM PROCESSOR FOR AN IBM PC 300 SERIES SYSTEM. THE REPLACEMENT IS TO RESOLVE THE "REDUCED PRECISION" FLOATING POINT CALCULATION PROBLEM.

INTEL HAS ACKNOWLEDGED A DEFECT IN ITS PENTIUM MICROPROCESSOR THAT CAN CAUSE INACCURATE RESULTS IN SOME MATHEMATICAL APPLICATIONS. IN SOME CASES THE PRECISION OF THE PENTIUM DIVIDE OPERATION MAY BE REDUCED.

PHYSICAL CHECK:
ALL SYSTEMS WITHIN THE ABOVE SERIAL NUMBER RANGES WERE MANUFACTURED WITH THE AFFECTED PENTIUM PROCESSOR. TO VERIFY THE 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 CPUIDIBM PROGRAM MAY ALSO BE OBTAINED FROM THE IBM PC COMPANY BBS SYSTEM BY CALLING 1-919-517-0001. LOCATE THE
"MISCELLANEOUS FILES" SECTION (SECTION #7) FOR THE FILE TITLED "CPUIDIBM.DSK."

THE CPUIDIBM PROGRAM MAY BE DOWNLOADED VIA THE INTERNET FROM THE IBM PERSONAL COMPUTER FILE LIBRARY BY SEARCHING THE FOLLOWING INTERNET URL:
