We've been getting machine check 2, cp tbuf par faults. I don't think 4.1 knows how to deal with it but 4.2 does. However it would be even better to eliminate them completely. DEC is willing to upgrade the CPU from rev level 3 to rev level 7. But the rev 7 CPUs store their microcode in RAM. Presumably there is a method that VMS sites use to load the microcode but is it possible for Unix sites to get the microcode loaded? Has anyone dealt with and solved this problem already? -- I'm going to keep boring until I strike oil.
