1-20 Chapter 1: 7401-2xxx and 3xxx Product Overview
The Processor Boards support linear addressing by creating a "hole" in
the memory address space at the 63 MB boundary. When the system is
configured for 64 MB and linear addressing is enabled, the last 1 MB of
system memory is unusable; therefore, the board will report that total
available system memory is 63 MB.
Because a hole in memory creates a non-contiguous address space,
enabling linear addressing when total system DRAM is greater than 64
MB is not recommended. Video linear addressing is enabled through
PC Setup under the Integrated Peripherals menu.
The processor also supports VESA standards such as the VESA DPMS
protocol to place a DPMS compliant monitor into power savings
modes.
