Emulated IRQ Solution

All PCI-E devices are required to support Message Signaled Interrupts (MSI).

However, some legacy operating systems might not recognize MSI. This feature

provides a workaround solution for a PCI-E device to function properly in a system

that is supported by a non-MSI aware OS. When this item is set to Enabled, a

PCI-E device will generate a memory transaction with a correct PAR (Pin Assertion

address and date registers, so the BIOS can initialize this PCI-E device before

booting the OS. The options are Enabled and Disabled.

PCI-Exp. I/O Performance

Some add-on cards perform faster with the coalesce feature, which limits the payload

size to 128 Bytes; while others, with a payload size of 256 Bytes which inhibits

the coalesce feature. Please refer to your add-on card user guide for the desired

setting. The options are Payload (256 Bytes) and Coalesce.

PCI Parity Error Forwarding

The feature allows SERR and PERR errors detected in PCI slots to be sent

Enabled and Disabled.
