Headless (Serial Console) Installation?

Is it possible? I'm attempting to install on a device which has no video card. I can see the options over serial once it boots -

"boot:" prompt and instructions about Enter, F1 and F3. But after that nothing shows on the serial console.

Is it possible to perform the install this way?

I guess no but I made this script some time ago to automate ASG ISO installations. You can use the installer.ini file to burn-in custom settings into the modified ISO.

Basically you run it on a Linux box:

sudo asg2asi.sh asg-9.004-33.1.iso

This will produce a modified, automated ISO that you can burn or put on an ASI/SUSI stick. If you don't want to further customize the ISO, delete the installer.ini file and it will use the defaults (except timezone).

asg2asi.sh

#!/bin/bash

CWD=`pwd`
BASE="/tmp/$$.asg2asi"
ISO=`basename $1`
ISOPATH="`dirname $1`/$ISO"
ISOTYPE=`echo $ISO | cut -d '-' -f 1`
ISONAME=`echo $ISO | cut -d '-' -f 2-`
BISO="$BASE/iso"
BPATCH="$BASE/patched"

on_die() {
  echo "Interrupting..."
  cd "$CWD"
  if [ -e "$BISO" ]; then
    sudo umount "$BISO"
  fi
  exit 1
}

trap 'on_die' TERM
trap 'on_die' KILL
trap 'on_die' INT

if [ ! -e "$ISOPATH" ]; then
  echo "Please specify an existing ASG ISO file: asg-*.iso"
  on_die
fi

if [ ! "$ISOTYPE" = "asg" ]; then
  echo "Sorry, only ASG ISOs supported"
