Well there IS one virus that will write its self in the BIOS, only
on flastbios mother boards. And I did find it some time ago on
the internet, but since then the procedure to reprogram the flask
bios on mother boards has been changed... I hope. Now some modens
can have their eeprom also over written, and their has been
extensive messages on it wither it was hardware damage or not.
