!!Note: For new installations: the PC Engines APU platform will be soon EOL :-(!!

**Serial Console COM Port:**

!!Note ->!! Skip this section for AstLinux 1.3.0 and later, which uses a ''115200'' baud rate.

For AstLinux 1.2.10 and earlier, the board type of "genx86_64-serial" defaults to a 19200 baud serial console, unfortunately the PC Engines's BIOS is fixed at 115200 baud, so if you want to view the BIOS console you must change the AstLinux serial console speed to match at 115200 baud.  After
**[[userdoc:new-install#persistent_storage_options_gui|persistent storage]]**
has been configured, from the CLI issue the following command:

  setconsole-speed-tty 115200 ttyS0


!!Tip ->!! A reboot is required for the change to take effect.

!!Note:!! Wake-on-LAN (WOL) does __only__ work on eth2 (next to the USB ports)!
