5.6 Shadow Configuration Setup Screen
The system’s Shadow Configuration Setup Screen (Figure 7) allows the selective enabling and
disabling of shadowing in 16 Kbyte sections, except for the top 64 Kbytes of the BIOS ROM,
which is shadowed as a unit. Normally, shadowing should be enabled at C000/C400 (to enhance
VGA ROM BIOS performance), and then E000-F000 should be shadowed to maximize system
ROM BIOS performance.
