The registers for the System Management Bus (SMB) are
divided into two sets:
• Standard GeodeLink Device (GLD) MSRs (Shared with
• SMB Native Registers
The MSRs are accessed via the RDMSR and WRMSR pro-
cessor instructions. The MSR address is derived from the
370
DIVIL, see Section 6.6.1 on page 317.)

Addressing" on page 59 for more details.
The Native registers (summarized in Table 6-27) are
accessed via Base Address Register MSR_LBAR_SMB
(MSR 5140000Bh) as I/O Offsets. (See Section 6.6.2.4 on
page 327 for bit descriptions of the Base Address Regis-
ter.) The reference column in the summary table points to
