space for ISA expansion cards that specifically require this

system .Expansion cards can only access memory up to 16 MB. The

default setting is "Disabled".

The chipset has an embedded 32-bit posted write buffer to support

delayed transactions cycles. Select Enabled to support compliance

with PCI specification version 2.1.
