Flash BIOS update - flash from operating system version for IBM NetVista 6266, 6270, 6276, 6279, and 6280 systems PUKT21A README This package updates the basic input/output system (BIOS) on IBM NetVista(R) model 6266-xxx, 6270-xxx, 6276-xxx, 6279-xxx, 6280-xxx, and 6286-xxx computers. 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.
