Setting the Processor Speed
The CPU Speed option sets the processor speed to fast or slow.
At fast speed, your processor operates at its highest speed. At
the slow speed setting, the processor operates at 8 MHz to
provide compatibility with older application programs. Leave
it set to fast speed unless you know your application program
requires the slow setting.

Relocating memory
The Relocate Memory option relocates the memory between
A0000h to BFFFFh and D0000h to EFFFFh for use as extended
memory. If you enable shadowing between D0000h and
EFFFFh, however, relocation is automatically disabled.
Shadow RAM options
Your computer can access RAM (random access memory)
faster than ROM (read only memory).
The Shadow BIOS ROM (always enabled) and Shadow Video
ROM
options allow your system to copy the contents of its
system and/ or video ROM into RAM so it can perform certain
operations faster.
