PCI DEVICE LATENCY TIMER
This parameter allows you to set the length of time for a PCI device to
use the PCI bus.
A PCI master can burst indefinitely as long as the target can
source/sink the data, and no other agent requests for the bus. If
another PCI device requests for the use of the PCI bus, a PCI bus
arbitration takes place, and the tenure of the device currently using
the PCI bus cannot go over the PCI latency time set in BIOS. This
setting depends on your application. For example, if you install a high
bandwidth block I/O card, e.g., FDDI, the longer the latency time the
better. This setting only affects the primary PCI components (PCI
slots 1, 2, 3, AGP slot, and onboard LAN).
components are always set to 20 PCI clocks.
