A quick search turned up this...

	This BIOS feature controls how long a PCI device can hold the PCI bus before another takes over. The longer the latency, the longer the PCI device can retain control of the bus before handing it over to another PCI device. For better PCI performance, a longer latency should be used. Try increasing it to 64 cycles* or even 128 cycles. The optimal value for every system is different. You should benchmark your* PCI cards' performance after each change to determine the optimal PCI latency time for your system. In addition, some time-critical PCI devices may not agree with a long latency. Such devices require priority access to the PCI bus which may not be possible if the PCI bus is held up by another device for a long period. In such cases, it is recommended that you keep to the default PCI latency of 32 cycles.
