SYSTEM BIOS CACHEABLE:
Selecting Enabled allows caching of the system BIOS ROM at F0000h-
FFFFFh, resulting in better system performance. However, if any program
writes to this memory area, a system error may result.
VIDEO RAM CACHEABLE:
Selecting Enabled allows caching of the video BIOS ROM at C0000h to
C7FFFh, resulting in better video performance. However, if any program
writes to this memory area, a system error may result.
VIDEO BIOS CACHEABLE:
Select Enabled allows caching of the video BIOS, resulting in better system
performance. However, if any program writes to this memory area, a system
error may result.
ONCHIP USB :
This should be enabled if your system has a USB installed on the system
board and you want to use it. Even when so equipped, if you add a higher
performance controller, you will need to disable this feature.
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 BURSING :
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.
