Configuration Summary

•Supported processors: P54C and P54CS.

•Level-2 cache memory socket - supports 256-KB cache memory module (the module is already installed in some PCs).

•Intel SB82437/8 PCI chipset which consists of four chips that interface between the three main buses (the processor’s local (PL) bus, the PCI bus, and the ISA bus).

❒The PL/PCI bridge chip (SB82437FX-66) which also provides control for the PCI bus, level-2 cache memory, and main memory.

❒Two data path unit chips (SB82438FX) that provide a 64-bit data path between the processor local bus and main memory modules.

❒The PCI/ISA bridge chip (SB82371FB) which also provides control for the IDE.

•Six SIMM sockets for EDO or FPM DRAM - up to 128 MB.

•Onboard video controller (S3 Trio64) offers full compatibility with VGA. Note that one model (D4471A) uses a Matrox MGA Millennium video card instead of the onboard video controller.

•Super I/O controller (SMC FDC37C932), driven from the ISA bus, supports two serial ports and one bidirectional multi-mode parallel port. It also provides control for two slow mass-storage devices (any suitable combination of floppy disk and tape drives).

•Little-Ben chip which takes care of security features and power management.

•128-KB flash BIOS
