AGP Aperture Size: It refers to a section of the PCI memory address range
used for graphics memory. We recommend that you leave this field at the
default value unless your AGP card requires other sizes.
ICH Delayed Transaction: Select [Enabled] will enable delayed transactions
for internal register, FWH, and LPC interface accesses.
USB Controller: Use this to enable or disable the use of USB controller.
USB Device Legacy Support: Use this to enable or disable support to emulate
legacy I/O devices such as mouse, keyboard,... etc.
CPU Thermal Throttling: Select [Enabled] will enable P4 thermal control
circuit to keep CPU from overheated.
DRAM Write Throttling: Select [Enabled] will enable north bridge thermal
management to keep it from overheated.
AGP/PCI Frequency: You may select among four sets of configuration options
as the AGP/PCI frequency. The default value is [67.2MHz, 33.6MHz], and
other configuration options are: [72.0MHz, 36.0MHz], [64.0MHz, 32.0MHz],
[76.0MHz, 38.4MHz].
SDRAM CAS Latency:
This parameter controls the latency between the read command and the
time the data available.
Configure SDRAM Timing by SPD:
SDRAM RAS# Precharge: This parameter controls the number of idle
clocks after a precharge command is issued.
SDRAM RAS# to CAS# Delay: This parameter controls the latency
between the active command and the read/write command.
SDRAM Precharge Delay: This parameter controls the minimum latency
between the active command and the precharge command.
