Flash BIOS update - bootable diskette version for IBM(R) NetVista(R) 6290 system version 26KT25A Installation README This package updates the basic input/output system (BIOS) on IBM NetVista(R) 6290 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. 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 26jt25a.exe in the search field, then click Find Now. This will locate the 26jt25a.exe file you just downloaded. 4. Double-click the 26jt25a.exe icon. 5. Follow the onscreen prompts. The necessary files will be extracted to the diskette. Installing the update --------------------- 1. Please make note of any settings you have changed in the configuration utility. They may have to be re-entered after updating the BIOS. 2. Close all open applications and shut-down the machine. 3. Insert the flash update diskette in the floppy diskette drive and power on the system. The current BIOS level on the computer is compared to that on the flash update diskette. 4. If the levels are the same, or the level on the diskette 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)" 5. Press Yes to continue. Update may take up to 2 minutes. Warning:Do not power off or restart the system during this procedure!! 6. Once the flash update is complete, remove the floppy diskette. 7. Press Enter to reboot the system. Flash Changes ------------- General Information: 26JTxxA is the flash diskette level. 26KTxxA 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 26KTxxA/26JTxxA: 26KT18A/26JT18A - Initial Production Release 26KT19A/26JT19A - Add support for Intel memory reference code 1.2 - In Setup, grey out PXE options when onboard ethernet is disabled - Fix for loss of USB 2.0 device after hibernation - Fix for restoring ATAPI transfer rate on resume from S3 under W98 - Fix occasional failure to wake from S3 via directed ping - Fix NT reboot problem - Fix Dual mode password 26KT20A/26JT20A - Fix incorrect Setup Summary Screen CPU speed - Update SM BIOS FSB speed during POST - In Setup, set PXE Boot & PXE Base to Enabled when System Board Ethernet is enabled - Disable native mode IDE support in ASL code - Correct the wrong prompt with power on password set - Update SMBIOS 4 to list the correct FSB speed - 0F27 processor microcode update - In Setup, enable PXE options when onboard ethernet is enabled 26KT21A/26JT21A - Fix problem with Intel Boot Agent not loading 26KT22A/26JT22A - Update of onboard video BIOS. Fixes intermittant video problems with DVO flat panel displays. - Fix "Compatibility Rev ID code". - Fix "Does not wake on LAN after losing AC power". We revert to a software approach where we power up, enable WOL, and go back down which is about three seconds into POST. - Fix fan failure which can occur if an application does not release the SMBus semaphore. - Fix Win ME resume hang when USB Device Support = Disabled. - New level of processor microcode update files. 26KT23A/26JT23A - Update of onboard video BIOS. Fixes video problems with the DVO flat panel displays. 26KT24A/26JT24A: - Fixed ACPI issue with UDMA slave device using capabilities of the master device - Fix data corruption on POV card and clearing 190 error - Fix potential bank 1 CMOS corruption due to SMI - Correct use of semaphores in SMBus code. 26KT25A/26JT25A: - Increased maximum processor speed reported by SMBIOS structure 4 to 2.8GHz Trademarks ---------- IBM and NetVista are trademarks of the IBM Corporation in the United States, other countries, or both.
