Questions and answers

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

b. Select File, then select Restore defaults.

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.
