What should I do if the Multicore CPU test returns "Misconfigured" in a Recovery environment?

Recovery environments that are based on Windows PE 1.6 (or earlier) only use a single core from each multicore processor. If all cores are enabled in the BIOS and in your main operating system, such as Windows Vista or XP, the multicore functionality is working fine.
