Specifying -maxcpus allows the user to cap the limit of possibly cpus of the system, as opposed to -smp which specifies the number of running cpus at startup. This allows us to build BIOS tables accordingly when trying to scale up in size, and it also allows for the BIOS to build smaller tables when not needed. I am going to submit a set of patches directly for BOCHS as well covering the BIOS part, but I am still waiting for my bochs-developers subscription to be enabled. Avi asked me to post this both for QEMU and the BIOS part for BOCHS. Cheers, Jes
