Accessing the BIOS on an x86 Switch
For x86 switches, if you need to access the BIOS, use the following steps (for example, if you need to change the serial console baud rate in the BIOS, if your switch’s default rate is different than the Cumulus Linux default of 115200).
The procedure varies with the switch manufacturer, so follow the appropriate steps for your switch.
