The following components require address space:

System ROM

Advanced Programmable Interrupt Controllers (APIC)

Integrated PCI devices (such as NICs) and SCSI controllers

PCI expansion cards

At start-up, the BIOS identifies the components that require address space. The BIOS dynamically calculates the amount of reserved address space required. The BIOS then subtracts the reserved address space from 4 GB to determine the amount of usable space.

If the total installed system memory is less than the usable space, all installed system memory is available for use only by the operating system.

If the total installed system memory is equal to or greater than the usable address space, a small portion of installed memory is available for use by the operating system.
