6220M Mainboard Chapter 3 Award BIOS Setup
27
EDO Auto Configuration
The first chipset settings deal with CPU access to
dynamic random access memory (DRAM). The default timings have been carefully
chosen and should only be altered if data is being lost. Such a scenario might well
occur if your system had mixed speed DRAM chips installed so that greater delays
may be required to preserve the integrity of the data held in the slower memory chips.
EDO DRAM Speed Selection
The DRAM speed is controlled by the DRAM timing
Registers. The timings programmed into this register are dependent on the system
design. Slower rates may be required in certain system designs
to
support
loose
layouts or slower memory. i.e. 50ns; 60ns
EDO CASx# MA Wait State
This item allows you to select EDO CASx# MA Wait
State. The choice : 1, 2
EDO RASx# Wait State
This sets the relative delay between the row and column
address strobes from DRAM (EDO). The choice : 1, 2
Auto Detect DIMM/PCI ClK
If this item is enabled, the unused DIMM and PCI slot
clock will be disabled. If this item is disabled the unused DIMM and PCI slot will still
get the active clock signal.
Spread Spectrum
Enable / Disable this item, the BIOS will Enable / Disable the
clock generator spread spectrum .
Software Clock Control
When disabled, the system will automatically set the base
frequency according to the CPU type :
Pentium
II 233~333MHz & Celeron
TM
266~466MHz: Set to 66MHz.
Pentium
II 350~450MHz and Pentium
III: Set to 100MHz.
When enabled, there is another item showed below: “CPU Host/PCI Clock” for user
to set the base frequency manually.
CPU Clock Frequency
Use this item to set CPU base clock frequency which
includes 66
、
75
、
83
、
100
、
103
、
112
、
124 and 133MHz.
Note: After you change the CPU Clock Frequency and the system can not start,
please do the following procedures:
1.
Turn the system off firstly.
2.
Turn on the system. Then press and hold the “ Insert ” key at boot.
3.
Select the proper frequency in the item of CPU Clock Frequency.
4.
Save and Exit Setup.
