B.3.5 C8000H – Dffffh Shadow - Acer AcerPower Flex4000 Series User Manual

B.3.5 C8000h - DFFFFh Shadow
The system reserves a portion of random access memory (RAM) for the shadow RAM
function. This parameter allows you to shadow the C8000h-DFFFF address range,
enabling I/O ROM functions to run directly from the shadow RAM for faster operation.
When you set this parameter to
some legacy ISA LAN cards, you might need to disable the shadowing in order for the
card to work properly. Default is Disabled.
