The 6x86MX (i.e. M2) is a 686-class chip. Michael, you are correct. However, I think the newer 2.2.2 snapshots (post 2.2.2R) are using the 686 compile settings for the M1 as someone reported... I haven't tested this myself, but someone earlier in this message thread I think said it was probed as a 686 class cpu and setting it to 486 cpu settings would cause a panic. (I agree that the 6x86/L should be properly labeled as a 586 class cpu despite its name). It comes down to whether choosing the cpu type depends on x86 instruction set compatibility, cpu speed class, or cpu name. I believe it used to be based primarily on instruction set (i.e. 6x86/L was 486); now it seems the compile settings are based on cpu speed. > > >Cyrix 6x86MX - 686 > >AMD K5 - 586 (?) > >AMD K6 - 686 (?) > [...] > > ----------------------------------------------------------------------------- > Michael L.
