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.
