IA: Xeon Enhancements

To maximize performance, Solaris 8 Intel Platform Edition now supports the Page Attribute Table (PAT) feature of IA 32-bit processors (Pentium II and Pentium III). This support enables a device driver writer to take advantage of the write combining feature for a device that can exploit write combining, even if the BIOS does not set up the device for write combining.
