1a) Choose the release of the BIOS, where the issue is solved.

1b) Choose the latest release and pray.
2) What to do if the disk does not functioning.

2a) - Try different disk (meaning the plastic ring)
- Try different disk writer/burner meaning a device and a software
- Try different release of the BIOS version (for ex., if you used floppy image, try a CD image then or some other type of BIOS installation utility available)

2b) - Try all options for 2a
- Try to download different version of BIOS (the first earlier than the tried one)
3) Why anything helps me???
3a, 3b, 3c...) Ask a person, who knows about BIOS and its updating, to do this for you. Serve him/her beer.
