When the UV BIOS starts the kernel it passes the UVsystab info struct to the kernel which contains information elements more specific than ACPI, and generally pertinent only to the MMRs. These are read only fields so information is passed one way only. A new field starting with UV5 is the UV architecture type so the ACPI OEM_ID field can be used for other purposes going forward. The UV Arch Type selects the entirety of the MMRs available, with their addresses and fields defined in uv_mmrs.h.
