Computer Knowledge: SHADOW
What is the SHADOW? The BIOS of standard video or interface cards is stored in ROM, and it is
often very slow. With the Shadow feature, the CPU reads the BIOS on the VGA card and copies it
into RAM. When the CPU runs this BIOS, the operation is speeded up.

kinds of devices during system booting. You can adjust the value to fit such devices. Larger values will
give more delay time to the device. The minimum number you can enter is 0, the maximum number you
can enter is 15. The default setting is
0 .
