I. CPU to PCI Write Buffer

When Enabled, CPU to the PCI bus are buffered, to compensate for the speed
differences between the CPU and the PCI bus.

J. PCI Delay Transaction

The chipset has an embedded 32-bit posted write buffer to support delay
transactions cycles. Select Enabled to support compliance with PCI specification
version 2.1.

K. Memory Parity/ECC Check

If the DRAM chips in your system support parity/ECC check, select Enabled
