    Intel Atom N270 - unknown CPUID cache descriptors

    bazie

      Hi,

      Recently I found out a strange output of CPUID in Intel Atom N270 processor. It gives cache descriptors (CPUID function 02h) of 59h, BAh, 4Fh, C0h, 80h and 0Eh which are not defined according to the most up-to-date version of Application Note 485 (August 2009). Could you confirm the same results? I use a simple program I have written in assembler for MS-DOS, but AFAIK CPUID works in all modes the same way.
