Install Debian over a serial console

Debian can be installed using the serial console.

First, if you're doing this via serial over LAN (SOL), you'll need to have enabled and configured it in the BIOS.

Next, boot the installer. When the installer boots, it loads into a GUI which will appear as a white screen to the serial console. Press ESC here to get to a boot: prompt, and then enter the following:

install console=ttyS0,115200n8

Adjust tty and baud values to match the values you configured in the BIOS. Now press enter, and you should see the text based installer start over the serial console.
