PCI Bridge
The PCI bridge chip (Intel 82454) provides high-bandwidth PCI compatibility for the system. The
bridge chip supports the primary PCI bus and is the path by which processors have access to all PC
compatible devices such as the ISA bus, BIOS PROM, and graphics controller. PCI slots 5 and 6 are
on the primary PCI bus. PCI slots 1 through 4 (secondary) are supported by an Intergraph
programmable part on the riser card.
PCI to ISA Bridge
The Intel 82379AB System I/O-APIC (Advanced Programmable Interrupt Controller) bridges the ISA
bus off the Primary PCI bus (PCI bus 0). The 82379AB supports all four ISA expansion slots.
Memory Components
Memory Sockets
The system board contains eight memory sockets which accept 72 pin SIMMs from Intergraph. The
sockets are divided into four banks. When all sockets are populated, the memory is four-way
interleaved which results in maximum memory performance. Refer to Chapter 4 for instructions to
upgrade memory. The following figure shows the socket numbers and bank organization.
