6.16 GeodeLink™ PCI Bridge Register Descriptions
All GeodeLink™ PCI Bridge (GLPCI) registers are Model
Specific Registers (MSRs) and are accessed via the
RDMSR and WRMSR instructions.
The registers associated with the GLPCI are the Standard
GeodeLink Device (GLD) MSRs and GLPCI Specific
MSRs. Table 6-91 and Table 6-92 are register summary
