The ECC mode needs 8 ECC bits for 64-bit data. Each time memory is accessed; ECC bits are updated and checked by a
special algorithm. The ECC algorithm has the ability to detect double-bit error and automatically correct single-bit error while
parity mode can only detect single-bit error.

The EDO DRAM technology is actually very similar to FPM (Fast Page Mode). Unlike traditional FPM that tri-states the memory
output data to start the pre-charge activity, EDO DRAM holds the memory data valid until the next memory access cycle, that is
similar to pipeline effect and reduces one clock state.

Traditional motherboard stores BIOS code in EPROM. EPROM can only be erased by ultra-violet (UV) light. If BIOS has to be
upgraded, you need to remove EPROM from motherboard, clear by UV light, re-program, and then insert back.
