The CELEBRIS Pentium computer is equipped with a 5V dc or 3.3V dc 256 KB external cache module. A

3) Unlock and remove cover.
4) Remove external cache from anti-static bag, and install it in socket.
5) Replace and lock cover.
6) Connect external devices and restore power.
7) If necessary, run BIOS Setup utility and enable external cache option.
