1. Maximize Memory below 4GB
Option Values: Enabled
Disabled
Help Text:
BIOS maximizes memory usage below 4GB for an OS without PAE support,
depending on the system configuration. Only enable for an OS without PAE support.
Comments: When this option is enabled, BIOS makes as much memory available as possible in
the 32-bit (4GB) address space, by limiting the amount of PCI/PCIe Memory Address Space
and PCIe Extended Configuration Space. This option should only be enabled for a 32-bit OS
without PAE capability or without PAE enabled.
