Mainboard User's Manual
OnChip USB: This should be enabled if your system has a USB in-
stalled on the system board and you wish to use it. The default is
Enabled.
USB Keyboard Support: Enables function when the USB keyboard
is being used. Disabled (default) when an AT keyboard is used.
OnChip Sound: When set to Disable, the onboard audio chip is
turned off. The default is Auto.
CPU to PCI Write Buffer: When enabled, up to four words of data
can be written to the PCI bus without interrupting the CPU. When
disabled, a write buffer is not used and the CPU read cycle will not
be completed until the PCI bus signals that it is ready to receive the
data. The default is Enabled.
PCI Dynamic Bursting: When enabled, every write transaction goes
to the write buffer. Burstable transactions then burst on the PCI bus
and nonburstable transactions do not. The default is Enabled.
PCI Master 0 WS Write: When enabled, writes to the PCI bus are
executed with zero wait states. The default is Enabled.
PCI Delay Transaction: The chipset has an embedded 32-bit posted
write buffer to support delay transactions cycles. Enable to support
compliance with PCI specification version 2.1. The default is E n-
abled.
PCI#2 Access #1 Retry: When enabled, the AGP Bus (PCI#1) ac-
cess to PCI Bus (PCI#2) is executed with the error retry feature. The
default is Enabled.
AGP Master 1 WS Write: This implements a single delay when
writing to the AGP Bus. By default, two-wait states are used by the
system, allowing for greater stability. The default is Disabled.
AGP Master one WS Read: This implements a single delay when
reading to the AGP Bus. By default, two-wait states are used by the
system, allowing for greater stability. The default is disabled.
