Dear John. >I couldn't find any docs that explain the CPUID >steppings for VIA CPUs, do you know of any? You can download programming_guide.pdf http://www.via.com.tw/en/initiatives/padlock/developercenter.jsp (http://www.via.com.tw/en/downloads/whitepapers/initiatives/padlock/programming_guide.pdf) There is it in VIA's CPUID table in the Page 4 nat the PDF. Nehemiah (C5XL) : Type 0 , Family 6, Stepping 3 Nehemiah (C5P) : Type 0 , Family 6, Stepping 8-F Ruth (C5Q) : Type 0 , Family 6, Stepping 1-7 Esther (C5J) : Type 0 , Family 6, Stepping 8-F These CPU cannot distinguish it only in CPUID. The difference of Nehemiah and Esther is CPU featuer flags(SSE2, SSE3, NX bit...). (umm... patch was not better for CPU name... ) >Seemingly this should be for 'c7' rather than 'c5j'? We use 'c3' for the VIA >C3 Nehemiah rather than 'c5p'. I leave the matter of the "name" to you. If these cpu features(SSE2 and SSE3) becomes effective(bsd.cpu.mk) and padlock is enabled(initcpu.c), I do not have any problem. The "name" is very very small problem(or not problem). sorry. --------------------------------- Never miss a thing. Make Yahoo your homepage.
