Getting back my ibook G4 booting into OS9 by correcting Open Firmware

Hey Everyone, I wanted to add to this.

Recently I messed up my OS9 boot and my ibook wasnt booting. It took me a couple of weeks to figure out how to add this script on the nvram in open firmware, because I didnt have any access to any OS. Here is what I did. (All of the commands I am going to post below are in Open Firmware)

In open firmware there is a variable called nvramrc, this var contains the contents (in open firmware language) of the script shared above. This is the script that patches your ibook G4 to make it bootable.

First thing to check is if you have the var set up in open firmware (if you dont, dont worry, I will explain how to adapt the bash script above to make it work) To do so type: printenv nvramrc

[quote author=Doggoli link=topic=4021.msg27261#msg27261 date=1507384197]
After googling for a bit i found a script that modifies the nvram to work but that didnt help...Do any of you have some ideas?
Here is the script i tried:
#!/bin/sh
echo Enabling OS 9 booting...
echo "You may have to enter your password"

--- Day 4: Repose Record ---
You've sneaked into another supply closet - this time, it's across
from the prototype suit manufacturing lab. You need to sneak inside
and fix the issues with the suit, but there's a guard stationed
outside the lab, so this is as close as you can safely get.
As you search the closet for anything that might help, you discover
that you're not the first person to want to sneak in. Covering the
walls, someone has spent an hour starting every midnight for the past

Approach:
if we assume the string is in ASCII, we can use an integer array of 256
chars and mark the used chars and add them.
Assuming the interviewer mentions the string is in UNICODE, then the max #
