CPU to PCI Write Buffer

PCI Dynmic Bursting

Disabled		Default
Enabled	Select Enabled if your system
	contains a Universal Serial Bus
	(USB) controller and you have a
	USB keyboard.
Disabled	When this field is Enabled, writes
Enabled	from the CPU to the PCI bus are	Default
	buffered, to compensate for the
	speed differences between the CPU
	and the PCI bus. When Disabled,
	the writes are not buffered and the
	CPU must wait until the write is
	complete before starting another
	write cycle.
Disabled	When Enabled, every write
Enabled	transaction goes to the write buffer.	Default
	Burstable transactions then burst on
	the PCI bus and nonburstable
	transactions don’t.
