yup... basically flash the bios with the same or updated bios file.
then turn on trendaway next time

.
worked with me back in '98 when i had a bios virus... its one of those things that are not so wide spread (thank god!)
If that doesn't work... guess your going to have to email your mobo manufacturer or computer manufacturer and tell them what happened and that you need a new bios chip
