1 Introduction
The SiS 551X / P54C PCI ma inboard is a high-performance system board that
supports Pentium P54CX and Cyrix 6x86 family CPUs. You can install 256K to 512K
of external cache memory on the mainboard. The mainboard is fully compatible
with industry standards, and adds many technical enhancements.
