Upgrading the CPU
The board supports the Pentium II processors with speeds ranging from 233 MHz to 450
MHz. It utilizes the new enclosed packaging technology called S.E.C (single-edge contact)
cartridge, that allows the second-level cache to remain tightly coupled to the processor. It is
capable of increasing the performance of 32-bit software and multimedia applications.
