These systems must contain a 2.5GB IDE hardfile, Microsoft WindowsNT 4.0 or Microsoft Windows95, and either of the following Busmaster IDE device drivers: Intel PIIX PCI Bus Master IDE Controller Intel 82371SB PCI Bus Master IDE Controller FEATURES: Type, Machines Affected Model, With and/or Feature/Device B/M to be Service System Stage B/M Description Installed Hours Hours 6577 B/M0000000 6577 PC 330 B/M0000000 00.2 00.1 MODELS - 7BT 7BJ,9BT,KBT 6587 B/M0000000 6587 PC 350 B/M0000000 00.2 00.1 MODELS - 7BT, 7BJ,9BT,K0U, KBT,KSX,L0U, LBV PHYSICAL CHECK: Affected systems contain at least one 2.5 Gb IDE hardfile with a FRU part number of P/N76H0961 and manufacturing part number P/N46H3431 or P/N46H3282. No other IDE hardfile used in the manufacture of the PC 300 6577/6587 or sold through Options By IBM (OBI) is affected. IBM (OBI) is affected. The system MUST be running a WindowsNT or Windows95 Busmaster IDE device driver obtained from the IBM PC Company BBS system or installed from the RTC CDROM that shipped with the PC 300 6577/6587. To verify that the Bus Master IDE driver is installed, perform the following steps appropriate for the operating system installed: WindowsNT 4.0 1. Double click "My Computer" icon. 2. Open the "Control Panel" folder. 3. Open the "SCSI Adapters" applet. 4. Select the "Drivers" tab. 5. If one or more instance of: "Intel PIIX PCI Bus Master IDE Controller" is listed, then you are using a Bus Master IDE device driver. Windows95 1. Select "My Computer." 2. Open the "Control Panel" folder. 3. Open the "System" applet. 4. Select the "Device Manager" tab. 5. Select "Hard disk controllers" from the list of devices. 6. If one or more instance of: "Intel 82371SB PCI Bus Master IDE Controller" is listed, then you are using a Bus Master IDE device driver. System diagnostics run without errors. PREREQUISITES: A system exposed to the failure MUST contain other IDE devices attached to the system board integrated IDE controller such as a secondary IDE hardfile or an IDE CDROM drive. The 2.5Gb IDE drive installed alone in a 6577/6587 will NOT exhibit the condition. COMPANION: NONE CONCURRENT: NONE DETAIL: A limited number of IBM PC300 6577/6587 Series systems containing a 2.5GB IDE hardfile may be exposed to a drive timing incompatibility condition which can potentially affect data transfer when the specified systems are used in conjunction with an IDE Bus Master device driver for WindowsNT or Windows95. The condition can result in a modification of data without any error indications or other evidence of system failure. The condition has been isolated to certain 2.5GB IDE fixed disks that were used in twelve PC300 6577/6587 models announced on January 8, 1997. Systems that do meet ALL of the conditions should have the Bus Master IDE Device Driver disabled until the following update is applied. The update program prevents the potential condition from occurring. Obtain the hardfile update program from the IBM PC Company BBS system by calling 1-919-517-0001. Locate the "IBM PC 300/700 Files" section (section #21) for the file titled: 25GBFIX.EXE The update program may also be downloaded via the Internet from the IBM Personal Computer File Library by searching the following Internet URL: http://www.pc.ibm.com/files.html NOTES: Physical replacement of the fixed disk is not necessary. Systems of the specified models which do not contain the 2.5GB IDE drive are not affected. Running the utility 25GBFIX.EXE will not affect existing data on the fixed disk drive. Running the utility on an IBM PC300 6577/6587 model that does not require it will have no adverse affects. This ECA provides labor reimbursement in situations where the Customer is unable or unwilling to install the hardfile update program on the PC 300 6577/6587. Any warranty claims submitted against this ECA that include parts are invalid.
