DDR400 tWRT Timing
This controls the timing delay (in clock cycles) before DDR400 starts a
write command after receiving it.  Settings: 1T, 2T, 3T.    3T increases
the delay time while 1T provides the least timing delay.   This option is
effective only if DDR400 is running.

when system wakes up (resumes) from S3 sleep state. The system resume time
is shortened when you disable the function, but system will need an AGP
driver to initialize the VGA card. Therefore, if the AGP driver of the card does
not support the initialization feature, the display may work abnormally or not
function after resuming from S3.

PNP/PCI Configurations
This section describes configuring the PCI bus system and PnP (Plug & Play)
feature.  PCI, or Peripheral Component Interconnect, is a system which al-
lows I/O devices to operate at speeds nearing the speed the CPU itself uses
when communicating with its special components.  This section covers some
very technical items and it is strongly recommended that only experienced
users should make any changes to the default settings.

BIOS Setup
PCI Latency Timer
This item controls how long each PCI device can hold the bus before another
takes over. When set to higher values, every PCI device can conduct transac-
tions for a longer time and thus improve the effective PCI bandwidth. For
better PCI performance, you should set the item to higher values. Settings
range from 32 to 248 at a 32 increment.
PCI IDE BusMaster
Set this option to Enabled to specify that the IDE controller on the PCI local
bus has bus mastering capability....
