Remote BIOS update from current running Linux OS
linux;bios
To update the BIOS, you need to use the AMI Update Utility (AFUDOS or AFUWIN).  These utilities are for DOS and Windows.  You have to boot into one of these OSes somehow (real DOS, not emulated).  Some ways you can get to DOS:You could create a DOS partition on the HDDs of the target systems, boot to it, run AFUDOS, and reboot.You could setup something with PXE to download a DOS floppy image and run AFUDOS from there.Both of these may require changing your Grub or BIOS boot order, which may require a physical visit to the PCs.  (At that point you might as well just use a USB key.)Some other options for remote management (if you have them setup):If these are server motherboards (e.g. Supermicro), you might be able to use the remote management port to get into the system.If these systems are Intel-based, you might be able to use Intel AMT to get into the systems.If you are really feeling bold, you can try using flashrom under Linux to flash the BIOS.  Note that by using an unsupported utility you increase the risk of bricking your motherboard.
