2-20 Setup and Operation

Latency Timer (PCI Clocks)

The Latency Timer (PCI CLOCKS) field controls the length of time an agent on the PCI
bus can hold the bus when another agent has requested the bus. Value choices range
between 0 and 256, the default value is 66.
In general this should not be changed. If there are latency sensitive cards in the system (such
as audio cards and/or network cards with small buffers) this can be set to a lower value to
reduce latency.
If there are no latency sensitive cards in the system, but I/O intensive applications are being
run, this can be increased to slightly improved performance.

PCI Burst

Disable PCI Burst when installing slower PCI video cards. The default is "Enabled".
