Memory Shadow Sub-Menu
The term “Memory Shadow” refers to the technique of copying information from ROM
into RAM and accessing it in this alternate memory location. The Memory Shadow
Sub-Menu is discussed below.
About Shadow Memory Regions
The shadow regions should be used only if an EXM module is installed in the system that
contains a BIOS ROM. Enabling shadowing for the region occupied by the ROM
increases system performance.
Do not enable shadowing for the region you may have specified for installing Flash or
VME disks. When these ROMs are installed, they are automatically shadowed.
