The bus and the cache RAM both! Unfortunately not many older or lower-end machines in the Intel world do have ECC on the cache, and very few have ECC on the data paths between the CPU and other devices. Most Pentium-Pro and all Pentium-II systems have ECC on the cache, and *can* have ECC on the data bus paths. I don't know how many actually have it enabled, though various server manufacurers, such as Dell, IBM, et al claim they've turned it on. > Basically all data paths need protection to cover all the bases. Buy a good Alpha or Sparc or Power-PC or really good P-Pro for this level of protection. -- Greg A.
