• EEPROM bytes 28h through 35h correspond to and are loaded into the configuration space for the first

downstream virtual bridge or port 1 (see Figure 4-1).

• EEPROM bytes 36h through 43h correspond to and are loaded into the configuration space for the

second downstream virtual bridge or port 2 (see Figure 4-1).

• EEPROM bytes 44h through 51h correspond to and are loaded into the configuration space for the

third downstream virtual bridge or port 3 (see Figure 4-1).
