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-specific 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-specific 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-specific memory
regions, but reduces the amount of usable memory in 32-bit
operating system.
