5.5. Change BIOS settings

The IPMI serial console can be used to configure BIOS settings remotely. To enter the BIOS setup you usually press F2 (ESC + 2) or DEL while the system is initializing.

Warning

Unfortunately, the hardware available at the MHPC lab does not support adjusting the BIOS via the serial console. To verify these following BIOS settings you will have to attach the screen and keyboard to each compute node.
