Flash BIOS update - CD-ROM ISO image version for IBM(R) ThinkCentre(R) 8095, 8098, 8141, 8142, 8143, 8144, 8145, 8146, 8171, 8172, 8173, 8420, 8421, 8422, 8423, 8424, 8425, 8426, 8427, 8428 Version 2BKT31A Installation README This package updates the basic input/output system (BIOS) on IBM ThinkCentre 8095, 8098, 8141, 8142, 8143, 8144, 8145, 8146, 8171, 8172, 8173, 8420, 8421, 8422, 8423, 8424, 8425, 8426, 8427, and 8428 systems. BIOS is programming that controls low-level hardware operations, including interactions with diskette drives, hard disk drives, and the keyboard. The BIOS is stored on a chip. Your computer uses flash BIOS, which can be updated through a program on a flash diskette so that you do not have to replace the BIOS chip to update the BIOS. Note: Make note of any settings you have changed in the BIOS Configuration Utility. These settings may have to be re-entered after updating the BIOS. Print this file so that you can refer to it during the installation. Important Note -------------- Installing this update involves creating a BIOS flash CD and running the flash program from the CD. You must have access to a CD-R or CD-RW drive and CD-R software which is capable of creating a CD from an ISO image. Downloading the update ---------------------- 1. Click the file link to download the file from the web page. 2. When prompted, select a drive and directory in which to save the downloaded file. Extracting the update --------------------- 1. Click Start, select Find or Search, then click Files or Folders. 2. Type 2bjz31usa.exe in the search field, then click Find Now. This will locate the file you just downloaded. 3. Double-click the 2bjz31usa.exe icon. 4. Click Next. Read the license agreement 5. Click I Agree. The installation folder should be C:\IBMTOOLS\FLASH\2BJZ31US. 6. Click Finish. You will be prompted with a message stating "The specified output folder does not exist. Create it?" 7. Click Yes. You will be prompted with a message stating "The package has been delivered successfully." 8. Click OK. Create the bootable CD ---------------------- Use your CD-R software's feature for creating a CD from an ISO image; Adaptec Easy CD Creator calls this feature Create CD from CD image. Refer to the help provided with your CD-R software for further assistance. Create a CD from the CD ISO image located in your C:\IBMTOOLS\FLASH\2BJZ31US folder. The filename of the ISO image is 2BJ931A.ISO. Installing the update --------------------- 1. Close all open applications. 2. Insert the bootable CD into your CD-ROM drive. 3. Shutdown the computer. 4. With the CD still inserted in the CD-ROM drive, power on the system. 5. When you are prompted to select a country, press the number on your keyboard which corresponds to the country in which you are using the computer. For example, press 1 for the United States. 6. Press Enter. You will be asked if you wish to update the serial number of your machine. 7. Press N. You will be asked if you wish to update the machine type/model number of your machine. 8. Press N. The Phoenix Phlash16 utility will appear onscreen. 9. Wait until you see a message stating that the update has completed successfully. 10. Remove the CD from the CD-ROM drive. 11. Press Enter. Note: If your system boots back to a 1962 POST error or displays a picture of a diskette on the screen, enter the Setup utility by pressing F1 during startup and change the Startup options to include your hard disk drive. Flash Changes ------------- General Information: 2BJTxxA is the flash diskette level. 2BKTxxA is the binary image level. (BIOS) NOTE: All changes carry forward. That is, if a change is added in 01, it is also in 02, 03 etc. Changes for 2BKTxxA/2BJTxxA: 2BKT31A/2BJT31A - Fixes a problem where the systems with the ATI PCIe graphics adapter will hang intermittently during POST - Fixes a problem where NX setup node does not display - Updates Memory Reference Code to version 1.40 2BKT30A/2BJT30A - Adds support for IDT clock generator chip - Fixes problems with IBM 128MB memory key where the system will not boot and where a PCI error occurs when copying in DOS - Fixes a TCPA problem where the system cannot extend PCRs 8-15 using INT 1A - Fixes a problem where the screen is blank instead of displaying Preboot Notification (PBN) text when PBN is set and F12 is pressed - Fixes a problem that occurs during S3 resume with a NVIDIA PCI Express adapter - Fixes a problem where that system will hang with 0F4x processors; Also adds thermal characterization for 0F4x processors. 2BKT29A/2BJT29A - Fixes a problem on the DDR system boards with the planar recognition and 3.4GHz/3.6GHz CPU support - Corrects the length of the SMBIOS asset tag string length on a system with POV 2BKT27A/2BJT27A - Fixes a problem that occurs when integrated video coexists with PCI Express interface with PCI as the active video. Makes it so only Integrated or PCI Express graphics port is enabled, never both. - Fixes a problem where the system will intermittently hang during power-on after CMOS battery removal - Updates Memory Reference Code to version 1.10 and Grantdsale BIOS spec update to version 1.20 - Fixes the CPU speed after returning from S3 resume - Fixes a problem where the system will hang when a SRCMOS capture is performed 2BKT26A/2BJT26A - This version was never released. Changes have been rolled into 2BKT27A. 2BKT25A/2BJT25A - This version was never released. Changes have been rolled into 2BKT27A. 2BKT24A/2BJT24A - Fixes a problem where the master hard disk drive password menu disappears - Fixes a problem where 3.6GHz processors may not run at full speed 2BKT23A/2BJT23A - Fixes Last Power State - Fixes a problem where a PCI VGA card can't be active when a PCIe video is present 2BKT22A/2BJT22A - Removes the display of the LAN oprom banner in Quick POST - Fixes a problem where a blank screen appears instead of the "Hibernating" progress bar with PEG video - Implements various ICH6 updates: BSU 1.1, BSU 1.3, and BSU 1.4 - Fixes a failure of the DMI log clearing utility introduced in 2BKT21A 2BKT21A/2BJT21A - Initial Production Release Trademarks ---------- IBM and ThinkCentre are trademarks of the IBM Corporation in the United States, other countries, or both.
