Flash Bios Dell
Chieko Boteler
From certain Bios version Dell started to emit Bios with higher security standard. Sad is that it doesnt work and only lock your machine bios not to be able to be upgraded any more. Just look to your Bios general page whether SFU is enabled. If so, you have no chance to upgrade your BIOS any more. Change is irreversible, just like stated in Dell sheet. It behaves just like described - flashing starts as usually but after restart doesnt continue - just loads OS again....
EDIT2: ME drivers did not help, neither did enabling/switching to legacy/UEFI, updating thru DOS also does nothing, updating thru BIOS just reboots as soon as i click "OK".... still stuck on A21, tried using the newer/updated Flash64 External which also does nothing
same issue here, laptop has bios A21 cant update to anything newer since bios wont load the update
EDIT: ill be looking into this, one thing i think might help is installing the Chipset drivers/Intel ME interface components, ill message back if this helps/solves the issue
