PCI Configuration Screen 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. Back to [PCI Configuration Screen] - [Advanced Screen] 2. Memory Mapped I/O above 4 GB 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.
