Most likely this memory is mapped into a region using memory management hardware and software or special chipsets on the motherboard, rather than physically existing there. Ordinary applications cannot use this memory easily. Using special utilities e. This helps free up conventional memory. High memory area is an area slightly smaller than 64Kb starting at the Kb boundary, available only on or higher computers.
Due to the design of the memory addressing of Intel microprocessors, you can address this space in real mode without switching to protected mode. With appropriate software, you can load device drivers and TSRs into this region as well. Quaterdeck's Desqview uses the high memory area, as does Windows 3.
The domain for these standards go beyond simple memory management, but they often include EMS and XMS support as well. Shadow ram is memory that is used to "shadow" ROM chips. Like this presentation?

Supplemental Information. Memory Specifications. The problem with this approach is that while in protected mode, DOS calls could not be made. The work around was to implement a callback mechanism. On the , this was a major problem. The Intel , which introduced "Virtual86 mode", allowed the guest kernel to emulate the and run the host operating system without having to actually force the processor back into "real mode".
It also permitted multiple protected mode clients. There are a number of other common DOS extenders. Wikimedia Foundation. Conventional Memory — [engl. Memory architecture — describes the methods used to implement electronic computer data storage in a manner that is a combination of the fastest, most reliable, most durable, and least expensive way to store and retrieve information.
