Flash BIOS update - CD-ROM ISO image version for IBM(R) ThinkCentre(R) 8127, 8128, 8183, 8184, 8185, 8186, 8187, 8188, 8189, 8190, 8192, 8193, 8194, 8195, 8196, 8197, 8320, 8416, 8418, 8419, 8432, 8433 Version 2AKT48A Installation README This package updates the basic input/output system (BIOS) on IBM ThinkCentre 8127, 8128, 8183, 8184, 8185, 8186, 8187, 8188, 8189, 8190, 8192, 8193, 8194, 8195, 8196, 8197, 8320, 8416, 8418, 8419, 8432, and 8433 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 2ajz48usa.exe in the search field, then click Find Now. This will locate the file you just downloaded. 3. Double-click the 2ajz48usa.exe icon. 4. Click Next. Read the license agreement 5. Click I accept the terms in the license agreement. 6. Click Next. 7. Ensure that "Save files in folder" is set to C:\IBMTOOLS\FLASH\2AJZ48US. 8. Click Next. 9. Click Finish. 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\2AJZ48US folder. The filename of the ISO image is 2AJ948A.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 -------------Phoenix Phlash16 Status------------- | | | Flash memory has been successfully programmed | | | | PRESS KEY TO RESTART THE SYSTEM | | If the system does not restart | | TURN THE POWER OFF, THEN ON | | | ------------------------------------------------- 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: 2AJTxxA is the flash diskette level. 2AKTxxA 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 2AKTxxA/2AJTxxA: 2AKT48A/2AJT48A - Fixes a problem where the asset tag is corrupted when the asset tag in EEPROM (POV-3) is longer than the one in flash. Limits the copy to the length of the flash string. - Fixes a problem in the Spanish language version of the Setup utility where the UUID is truncated - Fixes a problem where the BIOS flash diskette crashes if a wrong key is pressed. This was not a BIOS change, this is fixed by a new phlash16.exe, version 1.6.0.4. 2AKT47A/2AJT47A - Updates the fan control in an attempt to balance both thermal and acoustics. (Increases fan speed gradually by small steps instead of a big jump. Disables fan speed hysteresis when temperature gets above the voltage regulator overheat threshold, to cool it quickly.) 2AKT46A/2AJT46A - Adds new microcode for 0F34 (patch ID was 0Eh, now 13h) and 0F41 (patch ID was 05h, now 09h) - Adds a fan control update that will skip the voltage regulator temperature test on the small-form-factor chassis 2AKT45A/2AJT45A - Rerelease of BIOS 44A 2AKT44A/2AJT44A - Fixes a problem where the system will hang at boot when TCPA is enabled and a long bad password is entered - Fixes a problem where the system cannot extend PCRs 8-15 using INT 1A (TCPA) - Corrects the IOAPIC pin assignment for IRQ0/pin 2 - Fixes the support for the 0F41 (Prescott E0-step) processor 2AKT43A/2AJT43A - Fixes a problem where winphlash reboots the system unexpectedly - Fixes a problem where the LAN fails intermittently 2AKT42A/2AJT42A - Fixes a problem where the Pentium 4 logo is displayed when the system is using a 0F34 Prescott Celeron processor - Fixes a problem where the system hangs while booting Windows XP if the USB optical mouse is moved during the transition - Fixes a problem where the system hangs with 0F41 (Prescott E0-step) processor - Increases SMBIOS Type 4 structure maximum CPU speed entry from 3200MHz to 3400MHz - Fixes a problem where the system hangs if AC power is lost during S3 standby 2AKT41A/2AJT41A - Fixes a problem where the floppy diskette drive settings are lost when Setup is initiated from the IBM Predesktop Area - Fixes a problem where the system may hang during power on with a Token Ring adapter when the onboard Ethernet is enabled but the PXE Boot Agent is disabled - Fixes a problem on TCPA systems where the last five characters of the default asset tag string are not cleared 2AKT40A/2AJT40A - Corrects the display of characters in older DOS applications on non-English systems - Fixes a problem where the system constantly reboots in a loop with a Hitachi and Western Digital drive combination - Adds fan control to increase fan speed if the processor Voltage Regulator is over 70C - Adds an Intel errata patch for the microprocessor firmware to address a potential issue that might cause a system to exhibit erratic behavior such as a system hang, reboot, blue screen, or Kernel Panic in Linux, and may also cause in-progress system operations (e.g., file, I/O) to fail. The possibility of this behavior is believed to be limited, but IBM strongly recommends that customers install this update as soon as possible to prevent the possibility of the issues listed above. See Retain Tip H181898 for more details on this issue: http://www.ibm.com/pc/support/site.wss/document.do?lndocid=TCTR-ERRN91 The IDs of the affected microprocessors are 0F29, 0F33, and 0F34. NOTE: If you want to apply this processor patch without updating the rest of BIOS, refer to the "FLASHING BACK TO AN OLDER LEVEL OF BIOS" topic in the README.1ST file contained in this BIOS update package Determining the processor ID ---------------------------- There are several ways to determine the ID of the processor: 1. Go to BIOS setup (hold down the F1 key and power up the system) and look under the "Advanced" tab. (The processor ID is about 1/2 way down the screen.) 2. Use the Microsoft "System Information" tool. Go to the task bar and click through the following selections: Click Start, select Programs, select Accessories, select System Tools, then click System Information. The first screen displayed with this tool has processor information. For example, a F24 ID processor will have the following entry. (The "F" is translated to a "15" by this tool.) "Processor x86 Family 15 Model 2 Stepping 4 GenuineIntel .." 3. DMI information. The processor ID is presented in the DMI (Desktop Management Interface) Type 4 structure. There are various tools (DMI browsers) available to view this information. 4. If you have a Windows installation that for some reason does not have the "System Information" tool, a utility to display the processor ID can be obtained from Intel at the following URL: http://support.intel.com/support/processors/tools/frequencyid/ 5. System administrators may wish to refer to the following URL for an example of a Microsoft script file that extracts (among other things) the processor ID: http://www.microsoft.com/technet/community/scriptcenter/compmgmt/scrcm73.mspx 2AKT39A/2AJT39A - Fixes a violation of the USB 1.1 specification for Reset Recovery Time - Corrects the display of accented characters in some languages at runtime.
