  • Thanks for the information. This is very helpful and a great place to start. Grub sounds like the way to go. I have used grub in the past, but no more than using the arrow keys to select the os. The arduino's would send the power signal to the computers to boot, and then feed the bootloader the information telling it what to boot to? The serial console is via usb? How could I do this on two separate machines at the same time? Is it the same type of thing as using the serial console to monitor the arduino through the arduino++ software?

  • The arduino would listen to the serial port and wait for grub to be ready, usually it does this by printing a prompt (e.g. traditionally this has been "grub>" not super sure about newer versions though). If these computers have actual serial ports (i.e. 9 pin DSUB RS232) I would try and use that and connect to it via the UART port on the Arduino, using an adapter like I mentioned. Using the USB serial port might be possible, but it just depends on whether GRUB supports them. Commented Jul 9, 2015 at 22:35
  • As far as multiple computers go, you would pretty much have to go the UART route and get an Arduino that has more than one UART. For example the Due and the Mega 2560 have 4. Other Arduino-like boards like the Teensy 3.1 also offer extra UARTs. Commented Jul 9, 2015 at 22:37
