CPU to PCI Write buffer
When this field is
Enabled,
writes from the CPU to the PCI bus are 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.
PCI Dynamic Bursting
When
Enabled,
every write transaction goes to the write buffer. Burstable
transactions then burst on the PCI bus and nonburstable transactions don’t.
PCI Master 0 WS Write
When
Enabled,
writes to the PCI bus are executed with zero wait states.
PCI Delay Transaction
The chipset has an embedded 32-bit posted write buffer to support delay
transactions cycles. Select
Enabled
to support compliance with PCI specifica-
tion version 2.1.
PCI#2 Access #1 Retry
When disabled, PCI#2 will not be disconnected until access finishes (difault).
When enabled, PCI#2 will be disconnected if max retries are attempted with-
out success.
AGP Master 1 WS Write
When
Enabled,
writes to the AGP(Accelerated Graphics Port) are executed with
one wait states.
