Can a DOS-based MSR tool write to a specific core? (Developers)

posted by RayeR(R) Homepage, CZ, 19.07.2011, 18:18

I guess it needs APIC initialization and I don't know about any DOS app that handle it to utilize multicore. I remember there was a discussion and maybe Japheth tried some experiments with it. DJGPP and other DOS C compilers generate singlethread code without any control of APIC. In my case I use affinity function that works for windows and linux and compile to dummy function on DOS.

But I hoped if I will set multiplier/VID on one core it will set globally because CPU has only one PLL (I belive) and mobo has only one VRM. Please give me some time for experiments...

DOS gives me freedom to unlimited HW access.
