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 the number 0b1 is returned, that would indicate
that the PECI client supports two domains.

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 Revision Number always maps to the
revision number of this document.
