Intel Pentium Bug: Workaround (1st lvl cache)

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. | | Ralf Rudolph, Dipl.-Inf.
