I see other questions about this, but not clear on what problem could be. My AMD utility, SiSoft Sandra and WindowsXP Device Manager all report "unknown cpu type" since installing an AMD AthlonXP 2200+ on my Gigabyte GA-7DX mainboard. YES, I updated the bios prior to install which was supposed to aid in recognition of the 2200+. The AMD utility CPUID reports the correct speed, etc. but still the unknown cpu type. Fix? Need more info from me?
