In affinity mask each bit represents one CPU: 1 value - use CPU, 0 value - don't. Bits are counted from right to left, so you need do the same with CPUs. In our case, that would be: 7, 6, 5, 4, 3, 2, 1, 0. Now replace wanted CPUs with 1s and unwanted with 0s. You will get: 0, 1, 0, 1, 0, 1, 0, 1 or simply 1010101. Convert that from binary to decimal (use Windows calculator) and get a mask of 85.
