... Please, can anyone post a link where download the bios file....
Particularly where Acer's are concerned, always use the DOS method of BIOS updating. Windows is far from an ideal environment for such operations and I've seen quite a few perfectly good notebooks bricked.
There are retrieval tools for newer notebooks but success is not guaranteed and companies such as Acer seem hell bent on preventing you from successfully retrieving dead machines.
