Very old information.

Basically, shadowing BIOS means the PC will copy the BIOS from ROM chip to some of the "high memory" that sits between 640K and 1024K. Since back then reading RAM is faster than reading ROM, you get a performance increase.

The problem nowadays is BIOS is usually only used at the very beginning of the boot... and hardly ever after that. Everything nowadays is handled by Windows and its libraries and drivers, NOT through BIOS. Thus, ROM Shadowing will gain you very little, if any, performance gain.
