The integrated MAX1617 temperature sensors monitor the CPU temperature and the ambient
temperature around the CPU to make sure that the system is operating at a safe temperature
level. If the temperature is too high, the sensors automatically reduce the CPU clock frequency,
depending on the mode chosen in the BIOS set.
2.4.7
Serial EEPROM
A serial EEPROM is provided, organized into 4 blocks with 256 bytes per block (24LC08). This
EEPROM is connected to the I²C-bus provided by the ICH4.
2.4.8
BIOS FLASH (Firmware Hub)
For simple BIOS updating a standard onboard 1 MB Firmware Hub device is used.
The FWH stores both the system BIOS and video BIOS. It can be updated as new versions of
the BIOS become available. You may easily upgrade your BIOS using the Phoenix Phlash16
utility.
2.4.9
User FLASH
For small flash extensions an additional 1 MB Firmware Hub flash memory is available.
2.4.10
Dual BIOS
Dual BIOS means that there are two chips for the BIOS on the CP605 board (BIOS Flash and
the User Flash). One chip is intended to act as a backup in the event that the other one gets
corrupted. These chips are soldered on to the board.
