BiOS shadow memory

Because the ROM used by the BIOS is much slower than the normal Memory RAM we use, people come up with the idea of copying the information in the BIOS Rom to the memory stick (RAM) we inserted after the boot) to improve the reading speed, and the BIOS information in Ram is called the BIOS shadow memory.
Boot-generally press del to enter BIOS for viewing.
BiOS shadowed (BiOS positions include system BIOS ing, video BIOS ing, and video memory buffering !) Set the video BIOS shadow to enabled. Maps the BIOS on the video card to the memory to increase the display speed.
Set system BIOS shadow to enabled. The system BIOS is mapped to the memory to improve performance.
Set the video BIOS cacheable to enable. Maps the BIOS on the video card to the cache.
Set system BIOS cacheable to enbaled. Map the BIOS of the motherboard to the cache.
In the main menu, enter advanced BIOS features and you will find it. Of course, some motherboard BIOS projects are not covered here. It may also be found in the overall peripheral settings of Integrated peripherals.
Adjust Pagedown to enabled on the keyboard to enabled; otherwise, disable. After the adjustment, press the F10 key to save and exit, and restart the computer.
System BIOS shadow and system BIOS cacheable are rarely used in these two systems, so there is no need to adjust to enable ing. If you want to try it, it is not possible. If the system function is abnormal or conflicted after it is enabled, the ing function is disabled.
After the video BIOS shadow and video BIOS cacheable are enabled and used on poorly configured machines, we recommend that you enable them.
