Processor Information ROM (PIROM)
The lower half (128 bytes) of the SMBus memory component is an electrically programmed read-
only memory with information about the processor. This information is permanently write-
protected. Table 35 shows the data fields and formats provided in the Processor Information ROM
(PIROM).
