Flash BIOS update - CD-ROM ISO image version for ThinkCentre M55 (type 8009, 8010, 8011, 8012, 8791, 8792, 8793, 8794, 8795, 8796, 8797, 8798, 8799, 8800, 8801, 8802, 8803, 8804, 8805, 8806, 8807, 8808, 8810, 8811, 8812, 8813, 8814, 8816) Version 2JKT32B Installation README This package updates the basic input/output system (BIOS) on ThinkCentre 8009, 8010, 8011, 8012, 8791, 8792, 8793, 8794, 8795, 8796, 8797, 8798, 8799, 8800, 8801, 8802, 8803, 8804, 8805, 8806, 8807, 8808, 8810, 8811, 8812, 8813, 8814, and 8816 systems. This package is for use with systems that are not AMT capable. BIOS is programming that controls low-level hardware operations, including interactions with diskette drives, hard 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. Determining if system is AMT capable ==================================== 1. Click Start, then click Run. 2. Type msinfo32.exe, then click OK. 3. Select System Summary. 4. Look for BIOS Version/Date. You should see a value similar to either '2MKTxxAUS' or '2JKTxxAUS'. If the first two characters of the value are '2J', then your system is not AMT capable and this package applies to your system. 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 package ======================= 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. Create the bootable CD ====================== Create a CD from the CD ISO file, 2jj932b.iso. Use your CD-R software's feature for creating a CD from an ISO image; RecordNow! calls this feature "Burn Image". Refer to the help provided with your CD-R software for further assistance. Installing the package ====================== 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. The current BIOS level on the system is compared to that on the flash update CD. If the levels are the same, or the level on the CD is older than the ROM, a message is displayed stating: "BIOS ROM file is older than (or same as) BIOS ROM image. Continue Anyway? (y/n)" 6. The update may take up to 2 minutes. Do not power off or restart the system during this procedure! 7. Wait until you see a message stating that the update has completed successfully. 8. Remove the CD from the CD-ROM drive. 9. 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. Summary of changes ================== General Information: 2JJTxxA is the flash diskette level. 2JKTxxA 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 2JKTxxA/2JJTxxA: 2JKT32B/2JJT32B - Updates Intel Conroe CPU microcode 2JKT32A/2JJT32A - Fixes a problem where the system fails to update TCG PP (Physical Presence) from operating system (Move TCG PHS call from _SST back to _PTS, CRB was wrong) - Fixes "Invalid password in case setting pop with ten keys" - Fixes a problem where huge hard drives are not recognized - Fixes a problem where GetAssetData fails 2JKT31A/2JJT31A - Fixes a problem where the system has a bad start sequence on first POST after CMOS failure or reset - Fixes a problem where the system will not boot to network (Actual symptom: Kill AC + battery, won't boot to network on first POST, only second and subsequent) - Fixes a problem where an unsupported system shows the Cover Tamper setting 2JKT30A/2JJT30A - Fixes a problem where a corrupt screen randomly appears at POST screen 2JKT29A/2JJT29A - Fixes a problem where the hard drive LED is always lit on select systems that have no slim optical drive - Fixes a problem where the system cannot detect a PCI-E 1x LAN card - Fixes a problem where the system shows a yellow mark for PCI-Express ports under windows When 4GB memory is installed 2JKT28A/2JJT28A - Fixes a problem where the system hangs at POST screen after ME is disabled - Fixes a problem where a USB key for factory mode setup does not work - Fixes a problem where a wake event is always logged as 'unknown' 2JKT27A/2JJT27A - Fixes a problem where the system cannot access ME setup with a fingerprint keyboard - Fixes a problem where the system hangs at POST screen after ME is disabled - Fixes a problem where a USB key for factory mode setup does not work 2JKT26A/2JJT26A - Enhances Fan Acoustics function in high mode - Fixes a problem where 186 and 190 POST errors do not stop POST - Fixes a problem where the system hangs at hard drive config screen when install Windows 2000 - Fixes a problem where the keyboard does not work when install Windows XP with an NVIDIA 7300LE video adapter 2JKT25A/2JJT25A - Fixes a problem where some Setup screens do not match help - Fixes boot block recovery from USB CD-ROM - Fixes a problem where IGD cannot start in Windows XP with PCIe-x1 card installed - Fixes a problem where the system hangs or displays a bluescreen error when insalling Windows Vista with PEG card - Fixes a problem where the system hangs after installing ATI X300 driver on Windows 2000 - Fixes an intermittent hang or bluescreen in Windows XP with Ricoh USB printer 2JKT24A/2JJT24A - Updates fan control support for the CPUID 0F49 processors - Removes exclamation marks in Device Manager when a PCI video card is installed - Ensures that the system can boot the primary boot sequence after a dead battery is replaced - Updates SMBIOS processor socket information - Adds additional TCG Vista updates - Fixes a problem where the system hangs immediately after updating the BIOS to level 23 - Fixes a problem when the CPUID is limited to 3 - Prevents corrupting boot block if it is updated after completing the manufacturing process - Fixes a highly infrequent problem when a USB device is plugged in to the system, BIOS USB keyboard emulation is enabled, and USB control is being handed off to Windows 2JKT23A/2JJT23A - Various TCG code updates required for Vista - Updates the Audio Verb Table for Vista 2JKT22A/2JJT22A - Corrects a problem setting up the caches on systems with the Intel(R) Core(TM)2 Duo Processors.
