Pci Resource Allocation
Ratio
Allocates PCI resources, buses, memory-mapped I/O (MMIO) space, and I/O
space. If set to Allocate Evenly, equal amount of memory is allocated to all the
resources when two CPUs are installed. When set to Allocate More to CPU1,
larger amount of device-specic memory is allocated, which in turn reduces the
usable memory on a system with a 32-bit operating system.
Possible values are:
• Allocate Evenly
• Allocate More to CPU1
Microsoft Windows
Pci Mmio Space Size It allows you to reserve large or small device-specic memory regions to decrease
or increase the usable memory on systems with a 32-bit operating system.
Possible values are:
• Small — Allocates a small region of memory to PCI memory mapped I/O.
• Large — Allocates a large region of memory to PCI memory mapped I/O. This
reserves the large device-specic memory regions, but reduces the amount of
usable memory in 32-bit operating system.
