Intel Confidential QJ31ES / 90058007-0071 MALAY / i'98 80526KZ800256 2.8V

Another early Xeon sample. This one uses a classic P3 Coppermine core and features 256 KB of L2 cache. Beside the cartridge, it is strictly identical to others Pentium III. However, Intel rated the Xeon for multi-processing.
