BIOS Setup Information
Shadow Memory
(from address C000 – DFFF, 16K per segment)
Each segment provides three options
Disabled
,
Enabled
, and
Cached
for a
faster adapter’s ROM execution. However this shadow function is chipset oriented
and dependent on system hardware features. In general, C000 and C800 will be
allocated for VGA BIOS and set to
Cached
to get a higher display performance
using the shadowing and caching features. If the user chooses the
Enabled
setting, only the BIOS shadow function is active.
