Just to save anyone else some time...
Just bought a Foxconn K7S741GXMG-6L (from EBuyer in UK). Brand new etc.
etc.
It wouldn't install Windows (but Linux was fine). Sorted by updating the
BIOS from
www.foxconnchannel.com , now windows XP installing fine...

(PS the "Bundled" CPU cooler was garbage, ..., but the motherboard & Sempron
3000 for £66:37 seems reasonable...)
