Updating graphics bios in linux
Leave the stick plugged in to your computer and then restart the system.
Upon restart, enter the BIOS again using the method above.
Use the boards UEFI interface to navigate to the board’s BIOS update section usually dubbed “EZ-Flash,” “M-Flash” or the like.
Once started, you will be asked to navigate to the BIOS file.
Take the updated BIOS version and BIOS update utility you downloaded from the manufacturer’s website and copy them to the newly bootable USB stick. Once the prompt appears, you will need to type the exact name of your BIOS update utility or flash tool such as “bupdater” or “afudos” or “awdflash.” If your files and update tool are located within a different folder, such as ours seen in the image above, then you need to first access that folder using the command “cd\.
Our files are in “cd\TEST” again noted in the image above.
Look for debian-mac-XXX-amd64Also like the Macmini1,1; there will be an approximate 30 second delay before booting via BIOS emulation, for both booting from the CD and from the installed system thereafter.
(Tested on a macmini2,1: Intel Core 2 Duo 2.0 GHz, 4GB RAM, using debian-mac-8.4.1-amd64at search_keywords=Macmini2,1 boot from CD/DVD to boot into BIOS Compatibility mode; booting from USB causes the 3,1 to boot into EFI mode.
Like most things, a strong foundation is key to the efficiency of any system and updating your motherboard’s basic input/output system (BIOS) can do everything from adding new features and functions, support for new CPUs, squashing bugs, refreshing a corrupted UEFI environment, and much more.
You can also create one from an existing ISO image if you would prefer. This will take you to the Boot Selection where you can set a boot device.
Press and in a few short minutes your bootable USB stick will be ready. Make sure you set your bootable USB stick as your boot device and then press .
Going forward, each flash utility is a bit different but simple enough to understand.
Plus they all provide info on how to proceed once the application is initiated in DOS.
Debian installs fine in EFI mode, but freezes on boot when the nouveau FB driver tries to load due to the lack of a video BIOS.
