Description
In system/boot/platform/bios_ia32/smp.cpp if ACPI is disabled and the MPS tables are loaded, then the enabled flag is not checked for CPUs. This causes Haiku to fail to boot under KVM on Linux.

Updated patch which is much cleaner and doesn't rely on the enabled processors being the first ones.

The patch I've attached is sufficient in the case when the enabled CPUs are the first CPUs found. It is sufficient to allow Haiku to run as a KVM guest, but a more involved patch will be needed for proper support.
