Flash BIOS update for IBM(R) NetVista(R) 2255 and 2275 computers version P6JT28A README This package updates the basic input/output system (BIOS) on IBM(R) NetVista(R) 2255-xxx and 2275-xxx 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.
