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 8 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.
