Video shadowing is when a video card's BIOS is copied to system RAM for faster access. That was mostly only useful under real-mode operating systems such as MS-DOS, and was mainly only an option on older computers. The bus was quite a bottleneck, and ROM routines are slower than running them out of RAM, so it was faster to use a copy of the routines out of RAM. On boot, the system BIOS would create a copy of the video BIOS in RAM, protect that area of memory, and update the vector tables to point to it.
While such an option might make a computer seem to boot faster in some cases, shadowing the video BIOS didn't help under Windows. Windows requires drivers and the drivers are loaded into RAM, while the BIOS routines remained untouched. So if you didn't have much memory or conflicts were likely, you'd likely want to leave the shadowing disabled.
