Flash BIOS update - bootable diskette version for IBM(R) ThinkCentre(R) 8141, 8142, 8143, 8144, 8145, 8146, 8171, 8172, 8173, 8420, 8421, 8422, 8423, 8424, 8425, 8426, 8427, 8428 Version 2BKT35A Installation README This package updates the basic input/output system (BIOS) on IBM ThinkCentre 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. 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, be sure to select a path that does not have a space in it's name. Extracting the update --------------------- Installing this update involves creating a BIOS flash diskette and running the flash program from the diskette. Before you begin, have a blank 1.44 MB diskette ready. 1. Click Start, select Find or Search, then click Files and Folders. 2. Insert a blank 1.44MB floppy diskette into the diskette drive. 3. Type 2bjt35a.exe in the search field, then click Find Now. This will locate the file you just downloaded. 4. Double-click the 2bjt35a.exe icon. 5. Follow the onscreen prompts. The necessary files will be extracted to the diskette. Installing the update --------------------- 1. Close all open applications. 2. Leave the diskette in the A: drive, and shut down and restart the computer to start the BIOS flash program. 3. 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. 4. Press Enter. You will be asked if you wish to update the serial number of your machine. 5. Press N. You will be asked if you wish to update the machine type/model number of your machine. 6. Press N. The Flash BIOS update utility will appear onscreen. 7. Wait until you see a message stating that the update has completed successfully. 8. Remove the diskette from the diskette drive. 9. Press Enter. 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: 2BKT35A/2BJT35A - Adds an acoustics improvement - reduces the rate and size of fan speed changes - Fixes a problem where the system hangs at TP DAh with ATI PCIe graphics adapters and more than 3GB of memory - Fixes a problem with the OS/driver install for NVIDIA PCIe adapters 2BKT34A/2BJT34A - Adds support for 0F41 Prescott processor at full speed. Previous releases would leave it in Safe Mode under some circumstances. - Shortens the "System UUID" setup string to just "UUID" to prevent truncation of the UUID in some languages. Add periods at the end of the Italian and Dutch UUID help text strings. - Fixes a potential USB keyboard problem where the keyboard does not work or is slow to respond to keystrokes in DOS when loading the USB_CD.SYS DOS driver and no USB CD is attached - Adds a thermal control adjustment to reduce power-on fan speeds and to correct the TControl setup for 0F41 processor. To get the full benefit of this fix you must update the boot block. - Fixes a problem where systems with a Token Ring adapter hang during POST when onboard PXE Boot Agent is disabled 2BKT33A/2BJT33A - This level was never released 2BKT32A/2BJT32A - Fixes a problem where NX (No Execute Technology) setup node does not display - Adds microcode upgrades for 0F34 E0-step (patch ID was 0Eh, now 13h) and 0F41 E0-step (patch ID was 05h, now 09h) processors 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.
