Shadowing refers to the technique of copying BIOS code from slow ROM chips into faster RAM chips during boot-up so that any access to BIOS routines will be faster. DOS and other operating systems may access BIOS routines frequently.
Yintoni injongo yempendulo yesithunzi seBIOS?
The term BIOS shadow is the copying of ROM contents to the RAM, where the information may be accessed more quickly by the CPU. This copy process is also known as Shadow BIOS ROM, Shadow Memory, and Shadow RAM. The examples below are messages you might see when the computer first boots.
What is the purpose of the BIOS?
I-BIOS, kwiNkqubo epheleleyo yeNgeniso/yeMphumo, inkqubo yekhompyutha egcinwa ngokwesiqhelo kwi-EPROM kwaye isetyenziswe yi-CPU. ukwenza iinkqubo zokuqalisa xa ikhompyutha ivuliwe. Iinkqubo zayo ezimbini eziphambili zimisela ukuba zeziphi izixhobo zeperipheral (ikhibhodi, imouse, iidiski zokuqhuba, abashicileli, amakhadi evidiyo, njl.
What is shadowing in computers?
Webopedia Staff. A technique used to increase a computer’s speed by using high-speed RAM memory in place of slower ROM memory (RAM is about three times as fast as ROM). On PCs, for example, all code to control hardware devices, such as keyboards, is normally executed in a special ROM chip called the BIOS ROM.
How do I fix BIOS shadowing?

Yintoni ukuseta BIOS?
Yintoni i-BIOS? Njengeyona nkqubo ibalulekileyo yoqalo lwePC yakho, iBIOS, okanye iSistim yeNgeniso/yeZiphumo, yi isoftwe eyakhelwe-ngaphakathi yeprosesa enoxanduva lokuqalela inkqubo yakho. Ngokuqhelekileyo ifakwe kwikhompyuter yakho njenge-motherboard chip, i-BIOS isebenza njenge-catalyst yesenzo sokusebenza kwePC.
