May be... ;)
Interesting thing to note, the Biostar seems to search a strap in order to boot within the very high FSB range, let's say 530 to 600.
For instance, I've booted @600FSB*9, the post screen monitored 5.4GHz but actual clock was 3XXFSB*9 under windows. Then, it was required to boot @401FSB*9, and do it again @540FSB*9 in order to recover the real setting.
