This drivers is dated 14 September 01 and that makes it the latest version that seems to be available. Furthermore it was obtained from the PC-chips web site (they hide many of the pages to their older drivers/BIOS's).
It allows the clock multiplier to go up to 16x with my P-II which should make it useable with fairly new Celerons.
Other people have said it sorts out problems with large HD's. Try it and see. You will need to download the flash utility as well (available with one of the other Bios's on this site). My motherboard was V1.4 (if anyone needs to know).
