  • CPU ID changed from 0xF34h to 0xF41h
  • New processors require updates motherboard BIOS

More details are promised on July 14, 2004. The following processors are affected:

According to Korean Say25.com, 3.60GHz Pentium 4 LGA775 and respective i915P (Grantsdale) motherboard went on sale in the local market. Though I doubt there´s many of them, judging by "Intel Confidential" line on the chip. Seems like a sample delivered to one of their local labs.
