Datasheet
For platforms which do not implement any of the SMBus features found on the processor, all of the
SMBus connections to the 603-pin socket may be left unconnected (SM_ALERT#, SM_CLK,
SM_DAT, SM_EP_A[2:0], SM_TS_A[1:0], SM_WP). SM_VCC must be supplied when support
for future processors utilizing the 603-pin socket is desired.
NOTE:
Actual implementation may vary. For use in general understanding of the architecture. All SMBus pull-up and
pull-down resistors are 10K ohms and located on the processor.
7.4.1
Processor Information ROM (PIR)
The lower one kilobit portion of the processor SMBus memory component is an electrically
programmed read-only memory with information about the processor. This information is
permanently write-protected. Table 36 shows the data fields and formats provided in the Processor
Information ROM (PIR).
