Flash BIOS update - bootable diskette version for ThinkCentre(R) 8086, 8087, 8088, 8089, 8090, 8092 Version 2DKT13A Installation README This package updates the basic input/output system (BIOS) on ThinkCentre 8086, 8087, 8088, 8089, 8090, and 8092 systems. 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. 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 its name.
