As requested by many, the changes in the BIOS of an Olivetti M6 460 Suprema can be achieved in 2 ways. If the hard disc is the original one there is a time period of 5 seconds during startup of the computer, where the user can press CTRL-ALT-U to get into the BIOS settings. If this does not work you will need the included zip file. Prepare a bootable DOS disc and copy the unzipped files onto this floppy. Reboot the system with this disc and you will be able to go to the bios settings.
