Device Info
The Device Info byte gives details regarding the PECI client configuration. At a 
minimum, all clients supporting GetDIB will return the number of domains inside the 
package via this field. With any client, at least one domain (Domain 0) must exist. 
Therefore, the Number of Domains reported is defined as the number of domains in 
addition to Domain 0. For example, if bit 2 of the Device Info byte returns a ‘1’, that 
would indicate that the PECI client supports two domains.
2.5.2.2.3
Revision Number
All clients that support the GetDIB command also support Revision Number reporting. 
The revision number may be used by a host or originator to manage different command 
suites or response codes from the client. Revision Number is always reported in the 
second byte of the GetDIB() response. The ‘Major Revision’ number in 
always maps to the revision number of the PECI specification that the PECI client 
processor is designed to. The ‘Minor Revision’ number value depends on the exact 
command suite supported by the PECI client as defined in
