Screen Field Descriptions:
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.

Option Values: Enabled
Disabled
Help Text:
Enable or disable memory mapped I/O of 64-bit PCI devices to 4 GB or greater address space.
Comments: When enabled, PCI/PCIe Memory Mapped I/O for devices capable of 64-bit
addressing is allocated to address space above 4GB, in order to allow larger allocations and avoid
impacting address space below 4G.
