I agree we are very close, to that point. And it does look like However I suspect the 16G case to look like: > Setting variable MTRR 0, base: 0MB, range: 2048MB, type WB > Setting variable MTRR 1, base: 2048MB, range: 1024MB, type WB > Setting variable MTRR 2, base: 3072MB, range: 512MB, type WB > Setting variable MTRR 3, base: 3584MB, range: 256MB, type WB > Setting variable MTRR 4, base: 4096MB, range: 4096MB, type WB > Setting variable MTRR 5, base: 8192MB, range: 8192MB, type WB I hadn't realized we would start using > 1 mtrr after 4GB. The challenge is that the kernel really need to be shown how to handle overlapping mtrrs. That would let me handle the first 4 mtrrs (0-3) with just two mtrrs, fairly reliably.
