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
