In a best way "do it yourself", I fixed my AA1.
The steps I did:
1 - removed the additional 1Gb RAM;
2 - downgrade BIOS to 3114 version (the original) using Freedos + UNetbootin. Not the Fn + Esc tip;
3 - after the downgrade, my SSD appear normaly in the BIOS;
4 - Installed Fedora linux using using UNetbootin + Fedora ISO in a USB pen drive;
5 - back again with the additional 1 Gb RAM.
I'm posting from my recovered AA1 using the wireless connection.
Relified. Cheers. Christian.
