Aha! That might be the problem. Because there is still the factory BIOS, 
which is F11. I'll try the current F20 when I get home and I'll let you 
know.

Well as I said, with the native Mandrake kernel 2.6.8.1-12mdk everything 
was OK. First vanilla kernel I tried on this MB was somthing about 
2.6.9-rc2 if I remember correctly and it allready had the problem, and all 
subsequent ones had it as well.

OK, I'll take a look at it and let you know of the results (hopefully in
few hours).
