USB KEYBOARD SUPPORT:
Select Enabled if your system contains a Universal Serial Bus (USB)
controller and you have a USB keyboard.
ONCHIP SOUND:
This item allows you to control the onboard AC ’97 audio.
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 non-burstable transaction 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
specification version 2.1.
PCI#2 ACCESS #1 RETRY:
When disabled, PCI#2 will not be disconnected until access finishes. When
Enabled, PCI#2 will be disconnected if max retries are attempted without
success.
IO CHANNEL CHECK NMI:
This field enables or disables IO channel check NMI. Before selecting this
function, the user should check first that NMI function is enabled as described
in chapter 2 (Reset/NMI/Clear Watchdog Selection).
