--PciMmioSpaceSize
Table 301. --PciMmioSpaceSize
Attribute Details Description
Valid Argument Small, Large, Dynamic
Allocates a part of the memory to the PCI Memory Mapped I/O. 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.
• 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.
--PciResAllocationRatio
Table 302. --PciResAllocationRatio
Attribute Details Description
Valid Argument AllocateEvenly, AllocateMoreToCpu1
Allocates PCI resources, buses, memory-mapped I/O (MMIO) space, and I/O space. If set to
AllocateEvenly, equal amount of memory is allocated to all the resources when two CPUs are installed.
When set to AllocateMoreToCpu1, 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.
--PciSata
Table 303. --PciSata
Attribute Details Description
Valid Argument Enabled, Disabled
Enables or disables the PCI Serial ATA controller.
