BIOS Configuration
K7 CLK-CTL Select
This function sets the K7 clock controller. This setting should remain as
Optimal and should not be adjusted.
OnChip USB
The chipset contains an integrated USB controller. Select Enabled if you have
USB peripherals.
USB Keyboard Support
Select Enabled if your system contains a Universal Serial Bus (USB) controller
and you have a USB keyboard.
OnChip Sound
Integrated Audio is built into the KX-133 southbridge. Use this setting to
enable/disable the onboard sound feature.
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; nonburstable transactions do not.
PCI Master 0 WS Write
When this field is 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
transaction cycles. Select Enabled to support compliance with PCI specifica-
tion version 2.1.
PCI#2 Access #1 Retry
Select Enabled to rotate priority of PCI masters.
AGP Master 1 WS Write / Read
Select Enabled to add one clock tick to AGP write operations.
