Disclaimer
The idea of this blog it's just to post the BIOS history for Acer Aspire 5520/5520G from the first version up to version 1.33, the last one published as october 27th, 2009.
Why? Because I needed this information (to decide if I was to update the lappy BIOS or not), and it was nowhere to be found on the net. Now I've got it, I want to share it.
How did I get it? I asked Acer support, who kindly provided it to me. But it's still not published anywhere on the web...
I hope this provides useful for other owner of Acer Aspire 5520/5520G and any other covered by this BIOS.
Now a final statement: do not ask me for more information. I'm not Acer, I got this information asking, if you need other information, ask Acer or your lappy/mobo manufacturer. Not me. If you can improve this information in any way, please do it. Thanks.
The information
