--pcibuscount
Valid Argument 64, 128, 256
Description Sets the maximum PCI bus count for the system.
--pciersa
Valid Argument enable, disable
Description
Enables or disables the Reliability Availability Serviceability (RSA) support on PCIe devices.
--pcielinkspeed
Valid Argument auto, gen1, gen2
Possible Values auto, gen1 and gen2.
auto - PCIe link speed is congured based on the maximum speed supported by both upstream
and downstream devices.
gen1 - The PCIe link speed is congured in gen1.
gen2 - The maximum PCIe link speed allowed is limited to gen2.
Description Congures PCIe LinkSpeed.
--pcimmiospacesize
Valid Argument
small, large
Description Allocates a part of the memory to the PCI Memory Mapped I/O. It allows you to reserve large or
small device-specic 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 specic memory regions, but reduces the amount of usable memory in 32-bit
operating system.
--pciresallocationratio
Valid Argument
allocateevenly, allocatemoretocpu1
Description 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-specic memory is allocated,
which in turn reduces the usable memory on a system with a 32-bit operating system.
--pcisata
Valid Argument
enable, disable
Description Enables or disables the PCI Serial ATA controller.
