H System Boot Up Num Lock

This option can set the "Num Lock" key to "On" or "Off'after system boot

H External/ Internal Cache Memory

Due to constraint of technology, speed of currently available DRAM may

not be high enough to catch up with the speed of the CPU, which means that

at every step of program execution, the CPU must wait for the DRAM to

respond.

In fact, for CPU to run faster, the system must be designed to use another

kind of fast RAM chip —SRAM (Static-column RAM).

You can have a dual cache architecture - internal (from the CPU) & external

cache (from the SRAM).
