It's also interesting to note that this is no different than what Windows is doing. Windows 2000 "supports" the HT processors, but treats them as 2 separate physical CPUs. For a 2-CPU system, you actually need a 4-CPU license. For Windows XP, HT is "fully aware" and counts the logical cpus different than physical cpus. -- Ed Wilts, Mounds View, MN, USA mailto:[EMAIL PROTECTED] Member #1, Red Hat Community Ambassador Program -- Psyche-list mailing list [EMAIL PROTECTED] https://listman.redhat.com/mailman/listinfo/psyche-list
