Introduction

• The purpose of this article is to provide information on how to update the BIOS of a computer. It is ever all-time to fully review all documentation from the vendor regarding BIOS updates before proceeding. Even so, every bit a courtesy to the Ubuntu Community, information has been collected hither that others have successfully used to update their BIOS.

Considerations earlier updating the BIOS

Finding the right BIOS file

• When looking upwardly which BIOS file to download from a vendor'due south website, it is best to consult the sticker on the calculator itself, and non rely on the outcome of a terminal command (i.e. dmidecode). This is due to how the results of terminal commands can either be as well vague, or provide incorrect results for the computer due to the vendor not coding or properly documenting the data.

Reviewing installation instructions

• To ensure the best results, ane should review all documentation from the vendor. This may be a split README from their website.

BIOS update changes previously set configurations

• Some BIOS updates will add new settings within the BIOS, as well every bit adjust previously existing settings to something different than what was set previously. One would want to have note of the settings prior to updating, in case the desired settings do become changed, or the new feature would have an undesirable impact.

UEFI (Unified Extensible Firmware Interface)

• If the system has an UEFI (Unified Extensible Firmware Interface) based BIOS, one would want to fill-in the EFI segmentation first. To do then, copy the /kick/efi/EFI/ binder to a safe location. If the BIOS update either adjusts or removes it, 1 may restore it to its intended location, for example, via alive surroundings.

Acer

• For either the Acer Aspire 1 AOA110 Netbook or Acer Aspire I AOA150 Netbook please run into here.

Apple

• One may reinstall OS Ten for a firmware update following Apple tree'southward instructions here.

ASUS

• When looking up the model on the ASUS website, one may need to notice the model name every bit noted in the BIOS screen, which tin can differ from the sticker, or the result of a terminal command.

• For the model R554LA, the BIOS version found on the ASUS website is unlike, depending on if one goes to the Driver & Tools section, versus if one goes to the BIOS & FIRMWARE section.

• ASUS provides within their BIOS a utility called Easy Flash. Please search the Asus website for instructions.

• When searching for the latest BIOS update, please brand sure i checks the OS for both Windows and Linux to become the latest fixes. For example, the latest BIOS available for Windows was a later version in comparison to Linux for the Eee PC 1005HA Seashell.

Dell

• If you lot are using UEFI and your F12 boot options include "Flash BIOS upgrade", one may download the BIOS upgrade .exe from Dell's website, and put information technology to your /boot/EFI/ binder. Reboot and select "Flash BIOS upgrade" option. In the dialog select the .exe file you accept but downloaded and continue with the procedure.
  

  For more than on Dell specific procedures, delight see hither.

HP

Website bug

• Delight be advised HP was previously blocking review of their software updates (BIOS, firmware, drivers, etc.) from non-Windows operating systems for many PC models. This was last identified for HP Pavilion Elite d5200t ATX CTO Desktop PC but has since been partially stock-still. What happened previously was the Software & Drivers tab at the top was missing. If one uses any browser in Windows, the tab did evidence upward. To work around this problem, one may alter the URL from:

                http://support.hp.com/united states of america-en/product/HP-Pavilion-Elite-d5200-ATX-Desktop-PC-series/3824586/model/3824587

  to:

                http://back up.hp.com/united states-en/drivers/selfservice/HP-Pavilion-Aristocracy-d5200-ATX-Desktop-PC-series/3824586/model/3824587

  At present the tab shows up, but doesn't bring you lot to the drivers page for that model. Instead, one has to go lower in the page and click the button "Software and Drivers" and then click the button "Go".

Boot into BIOS (F10) to upgrade BIOS

• Ane may update the BIOS during startup via the F10 carte. Please keep in mind that the USB drive must be formatted with FAT32 (NTFS won't work).

Lenovo

• Lenovo makes bachelor up to iii different methods with which to update the BIOS. They are presented in the gild 1 should utilize them:

• A self-independent bootable ISO environment. In that location are instances where one may not update via the Windows .exe, and only update to a certain level via the ThinkVantage System Update. Hence, it is recommended to effort this first.

• Windows simply executable file.

• ThinkVantage System Update. In certain circumstances, the Windows but executable file may non piece of work. Withal, the ThinkVantage Organisation Update has a dissimilar update implementation, that may work when the Windows only executable file does non.

MSI

• MSI offers an update via a control from within the UEFI/BIOS to select and load a specific file from a USB bulldoze.
• Boot into the BIOS setup (by pressing DEL-cardinal while MSI splash screen is shown).
• Take note of the exact model (e.yard. GE70 2oe).
• Take notation of the currently installed BIOS version (e.g. E1757IMS.517).
• Have note of any changed configuration (as these will all be reset to defaults).

• Search MSI's website for the exact model (if you tin't find it, try to create an account and annals your device via its serial number from inside the bombardment compartment).

• Download and excerpt update file (~ 8 MB) to a USB stick post-obit this guide.

• Reboot into BIOS and showtime the update by selecting the file (e.k. E1757IMS.520).
• If after the update Ubuntu isn't starting and instead fails with a red failure dialog, check the kicking options in your BIOS (e.g. effort "UEFI with CSM").

Samsung

• Unfortunately, for many models, Samsung does non provide via their website the option to see the latest BIOS version, the release notes for a given BIOS version, or permit i to download a defended, Bone vendor independent BIOS upgrade method. Instead, they provide a Windows just software update programme called Samsung PC Update or SW Update, that is used to both check if a BIOS update is bachelor, and if so, then download and install via this program.

Toshiba

• Toshiba has made available a BIOS .exe for certain models (ex. Toshiba Satellite L305D-S5934) that when executed, generates an ISO to fire to disc, and in turn allows one to boot to the disc to update the BIOS. This .exe was successfully run in Ubuntu via WINE to generate this ISO, the ISO burned in Ubuntu, and the BIOS updated successfully.

Vendor contained updating methods

• Windows 10

  • Ane may temporarily install Windows 10 to update the BIOS from hither.

• Windows Evaluation

  • One may utilise an evaluation copy of Windows from here to update when ane may only use Windows.

• Windows System Repair Disc

  • In Windows seven, create a System Repair disc. Put the BIOS file on a spare USB drive (formatted every bit FAT32), boot to to the System Repair disc, navigate to the USB via command line and execute the file.

• USB Recovery Drive

  • In Windows eight.1, create a USB recovery drive. Put the BIOS file on the USB drive.

• Boot into Windows

  • I may do this via swapping in defended drive, or dual boot.

  • In a Windows Enterprise surroundings, use Windows To Go.

  • Request or download Windows recovery media from the vendor, and so one may employ it for an update.

• FreeDOS

  • Boot to FreeDOS and execute the .exe file. If ane is using UEFI, one may want to utilize Legacy fashion, versus UEFI.

• flashrom

  • http://world wide web.flashrom.org/Supported_hardware

• WINE

  • While Using WINE worked once for 1 person, for one piece of hardware, at i point in fourth dimension of Ubuntu and WINE development, it would exist considered a last resort. It would be conservative to believe that using WINE to update the BIOS holds a potentially higher risk in comparison to using Windows to damage your motherboard across troubleshooting, necessitating a warranty upshot or purchase of a new motherboard.
