3. 82460GX PXB (PCI eXpansion Bridge) connects the PCI 64/33 bus and core I/O (Ethernet LAN,
PS/2, parallel, serial, IDE, USB, VGA) and the baseboard management controller via one I/O
channel to the SAC
4. 82460GX SDC (System Data Chip) is the central memory data controller:
It connects to the data part of the FSB system main bus
Has a private link to the SAC (PD)
