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.

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. -Corey -- linuxbios mailing list linuxbios@linuxbios.org http://www.linuxbios.org/mailman/listinfo/linuxbios
