Common Options : Enabled, Disabled

Details

In most motherboards, the AGP bus-mastering device waits for at least 2 wait states or AGP clock cycles before it starts a read transaction. This BIOS feature allows you to reduce the delay to only 1 wait state or clock cycle.

So, for better AGP read performance, enable this option. Disable it only if you experience weird graphical anomalies like wireframe effects and pixel artifacts after enabling this option.

Note, however, that some motherboards apparently have an AGP master read latency of 0. So, enabling the AGP Master 1WS Read in this case will actually increase the latency by 1 wait state and reduce performance. Although that's really quite unlikely, that's what their manuals say.

Therefore, check your motherboard manual to see if the manufacturer has implemented the first (and more common) interpretation of the AGP Master 1WS Read BIOS feature or the second one. Either way, the lower the AGP master read latency, the higher the read performance of the AGP bus.
