Boot from external BIOS

MB-COME6-1
X23
SM Bus CLK 1 2 I2C Bus CLK
SM Bus DAT 3 4 I2C Bus DAT
SM Bus Alert 5 6 3V3
BIOS_DIS0# 7 8 GND
BIOS_DIS1# 9 10 GND

If there is no Jumper present on the BIOS_DIS1# signal the module will load its BIOS from the internal SPI flash.
If there is a Jumper on the BIOS_DIS1# signal (between signal and GND) the module loads its BIOS from the flash in the SPI socket of the carrier board.


Console Redirection

To display the BIOS over the serial port in addition to the display output on the Starterkit apply the following steps.
The 'Console Redirection' option for example may be useful for BIOS remote control tasks.

On Starterkit
  1. Connect a null modem cable to the desired serial interface (e.g. SER0)
  2. Boot the system into the BIOS menu
  3. Enable 'Console Redirection' option in the BIOS Menu (Setup Utility > Advanced > Console Redirection > enabled) and the corresponding serial port (e.g. COMA)
  4. Press <F10> to save the settings and reboot the system
On Host PC
  1. Connect the null modem cable to an available serial port
  2. Run your favorite terminal emulator on your Host PC (we recommend TeraTerm Pro)
  3. Configure the serial port according to the table below:
Serial port configuration
Baudrate Data bits Parity Stop bits Flow Control
115200 8 none 1 none

⇒ Reboot the Starterkit and use the terminal emulator to set up the BIOS



Hardware Monitor Fan Scaling

With 'Fan Scaling' option it is possible to control the system temperature at a certain load of the system by setting up the fan speed at certain trip points. To create a custom 'Fan Scaling' plan apply the following steps in the BIOS setup.

  1. Boot the system into the BIOS menu
  2. Enable 'Fan Scaling' option (Setup Utility > Advanced > SIO Hardware Monitor Nuvoton NCT7802Y > Enable Fan Scaling) and set it up according to your needs
  3. Press <F10> to save the settings and reboot the system
