With the latest microcde update, there's one big problem: size.
what is the size?
The full microcode update file is a little over 1MB, that's all the current updates for all CPUs, since the Pentium Pro. I've broken that down (with the help of a script) into individual updates, these range in size from 6-21K. Some CPU models have multiple updates, I'm not sure why, but my gut tells me they're all needed.
- The end user needs to select between p2 and p3 cpus for slot 1
systems. This may also come up in LGA775-based systems, due to size constraints
for slot 1, we no longer care. But, in general, we must ensure that any cpu can be plugged into a socket that is allowed and still have microcode updates work. Can you explain the lga775 issue a bit more?

Not yet, because I'm not even sure there's going to be an issue, I'm still working on the 6xx series. I've had to go to intel.com and compose a list of all the PPro, P2, and P3 (and Xeon/Celerons of the same era) CPU IDs, and break them down by model and package, so it's a fairly long process. If there is a problem, it'll be the same as with the slot 1s, there will be so many updates for so many CPUs that all of them simply can't fit into a 4Mb rom.
