5.6 Shadow Configuration Setup Screen
The system’s Shadow Configuration Setup Screen (Figure 5-5) 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.
