If you put the CD into the system and run the command:
diskutil list

It will give you a list of all of the drives that are mounted and their device name

Ok, first, it’s a script, which is intended to be copied and pasted into pico (or whatever text editor you use) and run as such. If you don’t know what you’re doing, you shouldn’t be in the command line anyway.

Second, I was mistaken, it’s not “injecting” code per se. It does leverage the VT-x technology built into the Core Duo, and elevates the code to a higher “ring” in the processor. If not done correctly, this can have serious consequences (hard crashes, data loss, etc.) You can read more about it here.

Ditto the previous two comments. Also note that the given /dev/ location for one’s optical drive is a likely one, but not necessarily the correct one.

There’s a good how-to at http://www.macfixit.com/article.php?story=20060407080157849

Yeah, none of those “rm” commands do anything about the kernel. None of those paths are kernel extensions. The closest thing is a startup item that may launch some background process. I don’t think it’s “injecting code at the kernel level” at all.

Whoa! Watch out for those shell commands in the previous message. If you make a typo such as putting a space between the / and the rest of the path then you can kiss your hard drive data goodbye.

The -r flag attempts to delete everything including directories and the -f flag does so without asking your permission.

Bad idea!

The proper address for your DVD-R drive is: /dev/rdisk2s0

Second, I would be very careful with Parallels’ software. It injects code at the kernel level, and I found my system to be very unstable while this software was installed on my system. Incidentally, here is a script to uninstall the Parallels’ stuff in case you need it (taken from a user at MacSlash… sorry, I don’t remember who):

#!/bin/sh
sudo /Library/StartupItems/Parallels/Parallels stop
sudo rm -rf /Library/Parallels
sudo rm -rf /Library/Receipts/Parallels.pkg
sudo rm -rf /Applications/Parallels.app
sudo rm -rf /Library/StartupItems/Parallels
sudo rm -rf ~/Library/Preferences/com.parallels.Parallels.plist
sudo rm -rf ~/Library/Parallels
sudo rm -rf ~/.parallels_settings

I know that this is beta software, but again, be very careful. I have a recent backup of my entire system, and I would recommend anyone who uses this stuff to have the same.
