The BIOS, or basic input/output system, gives users the option of changing the settings of their computer without booting into Windows, Linux or another operating system. Basic settings, such as changing the boot order and system date, are all accessible from within the BIOS, but accessing the BIOS menu requires pressing an access key at the correct time during the boot process. Each computer manufacturer uses a different access key or combination of keys to get into the BIOS settings. The Dell Latitude E6400 uses a single key stroke to enter into the BIOS settings.
