AGP Aperture Size
Selects the size of the Accelerated Graphics Port (AGP) aperture. Aperture
is a portion of the PCI memory address range dedicated for graphics memory
address space. Host cycles that hit the aperture range are forwarded to the
AGP without any translation. Options are 4M, 8M, 16M, 32M, 64M and
128M.
OnChip USB
This is used to enable or disable the USB ports. Settings are Enabled and
Disabled.
USB Keyboard Support
Set to Enabled if your system installs and uses an USB keyboard.
OnChip Sound
Auto allows the mainboard to detect whether an audio device is used. If the
device is detected, the onboard audio controller will be enabled; if not, the
controller is disabled. Disable the controller if you want to use other
controller cards to connect an audio device. Settings are Auto and
Disabled.
OnChip Modem
Auto allows the mainboard to detect whether a modem is used. If a modem is
detected, the onboard modem controller will be enabled; if not, the controller
is disabled. Disable the controller if you want to use other controller cards
to connect modems. Settings are Auto and Disabled.
CPU to PCI Write Buffer
When Enabled, CPU can write up to four words of data into the PCI write
buffer before the CPU must wait for PCI bus cycles to finish. When
Disabled, the CPU must wait after each write cycle until the PCI bus signals
that it is ready to receive more data.
PCI Dynamic Bursting
When Enabled, every write transaction goes to the write buffer. Then
burstable transactions burst on the PCI bus and nonburstable transactions
do not.
