Flash BIOS update - bootable diskette version for ThinkCentre(R) 8290, 8291, 8292, 8293, 8294, 8295 Version C915KT19A Installation README This package updates the basic input/output system (BIOS) on ThinkCentre 8290, 8291, 8292, 8293, 8294, and 8295 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.
