Questions and answers

1.

How can the BIOS settings be restored (returned to factory settings)?

a.

Turn on or restart the computer and press 

F10

 when prompted near the bottom of the display.

b.

Select Main, then select Restore defaults.

c.

Follow the on-screen instructions.

d.

Select Main, save changes and exit, then press 

Enter

.

2.

What kind of configuration data is stored on the DIMM Serial Presence Detect (SPD) memory 
module? How would this data be written?

The DIMM SPD memory contains information about the memory module such as size, serial number, 
data width, speed/timing, voltage and thermal information. This information is written by the module 
manufacturer and stored on an EEPROM. This EEPROM cannot be written to when the memory module is 
installed in a PC. Third party tools do exist that can write to the EEPROM when the memory module is 
not installed in a PC. There are various third party tools available to read SPD memory.

3.

Does the “Firmware Hub for System BIOS” contain the BIOS program? Is this chip writable, and if so 
how?

The Firmware Hub does contain the BIOS program and is writable. A utility is required to perform 
the write function.

4.

In some PC systems, the Firmware Hub for System BIOS is a flash memory chip so that updates can 
be written by the customer. Is this true for these BIOS chips?

Yes, they are flash memory chips.

5.

What is meant by “Restore the nonvolatile memory found in Intel-based system boards”?

This relates to clearing the Real Time Clock (RTC) CMOS memory that contains PC configuration data.

6.

Does resetting the CMOS configuration memory return the PC back to factory defaults?
