The VIA chipset will use fast write

Default

Enabled

to AGP if this item is enabled. Not

 

 

all AGP cards support fast write.

 

 

 

 

Disabled

This should be enabled if your

 

Enabled

system has a USB installed on the

Default

 

system board and you want to use it.

 

 

Even when so equipped, if you add

 

 

a higher performance controller, you

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.
