Installation Language was Spanish (and also Keyboard, and so on). I do not know for sure, but I think it happened running an installation 
selecting "automatic partitioning" having previous partitions on the disk, but I am not sure!.

The installation program told me to help the programmers inserting a diskette to save a file containing the following data:

-------------- [BOF] - BEGIN OF FILE ------------------------
