![]() The PnP/PCI Configurations page of a standard (non-UEFI) Award BIOS setup program The setting appears in the PnP/PCI Configurations page of a standard (non-UEFI) Award BIOS setup program, an image of which is shown below. All of the existing hardware configuration data is erased and then replaced, giving a fresh start that can resolve many hardware misconfiguration problems. That setting is enabled and the BIOS resets what the BIOS knows about all of the hardware components and peripheral devices (printers, etc.) and then disables the option so that its isn’t repeated with every system startup. Resetting the standard BIOS itself, dealt with above, so that the entire BIOS is reset must not be confused with its Reset Configuration Data setting of a standard (non-UEFI) BIOS that resets its hardware configurations. The Reset Configuration Data BIOS setting of a standard legacy BIOS Nevertheless, these passwords provide some limited protection from unauthorised access, because physical access to the computer, know-how and time is required to bypass them. The hard disk or SSD drive can also be removed and installed on another computer to bypass those passwords. If that is the case, you just have to plug the secondary chip into its socket in order to recover the BIOS. If you have a very recent motherboard, it may come with a secondary BIOS chip that plugs into the board and overrides the BIOS chip that is fitted to it. Showing the jumper settings on a motherboard to store or clear the BIOS settings Ports panel of an MSI MS-7673 motherboard showing its CMOS reset button A jumper placed over two pins on a motherboard that retains the BIOS settings. Here is a webpage on resetting the BIOS of a laptop: There may not be a jumper option and removing the BIOS battery could be difficult. Resetting the BIOS of a laptop is usually more difficult due access to the motherboard usually being very difficult. Click on them to see a larger version if one is available.Ī desktop PC’s motherboard manual provides instructions on how to do it. If, say, you have set a BIOS User or Supervisor Password and forgotten what it is, the BIOS can be cleared and reset to its default state either by enabling a jumper setting on the motherboard, which is usually beside the BIOS battery, as shown in the image below, or on some desktop PC motherboards by pressing a button on the ports panel.The images below show both options. Both passwords are usually limited to 8 characters and both can be bypassed by resetting the BIOS, usually by changing a jumper – a small connector placed over two pins – on the motherboard, or just by removing the BIOS battery. The Supervisor password protects the BIOS settings from being changed and the User password has to be entered at startup in order to boot past it. ![]() Note that with this particular standard BIOS there are options for a Supervisor and a User password, which not every BIOS provides. The page in an AMI BIOS setup program showing the settings for the boot order of devices – Floppy drive, USB drive, SATA hard disk drive The page in an AMI BIOS setup program showing the settings for the boot order of devices – Floppy drive, USB drive, SATA hard disk drive. The image below shows how the settings appear in a particular BIOS. For example if the CD/DVD drive is set as the first boot device and there is no boot CD/DVD disc in the drive, the BIOS will try to boot from the second boot device. If the first boot device contains no boot files, the BIOS uses the next boot device until it finds one that it can boot from. Some BIOSes allow you to set a USB flash drive or external hard disk drive as the first boot device. You will be able to set a floppy disk drive, CD/DVD, or hard disk drive, etc., as the first boot device. You can change the boot order of devices by dragging them into the first, second, third position, etc.įor example, in a standard (non-UEFI) Phoenix Award BIOS, in the Advanced BIOS Features section, you might see settings for First Boot Device, Second Boot Device, Third Boot Device, etc. ![]() ![]() You just have to click on the device you want to boot from and drag it to the first position. The new UEFI BIOS usually has selectable icons that represent the boot devices. For this particular BIOS the important navigation options are: The basic navigation instructions appear at the bottom of the main menu page and more detailed instructions appear on all of the pages listed on the main menu page. The menu presented by an Award standard BIOS Clicking on any image shows an enlarged version if one is available, which is the case with the one below. The image below is the much simpler menu presented by a standard BIOS created by Award that can only be accessed by pressing keys, because a mouse/touchpad doesn’t work at this level.
