well many people frown upon slayers cuz it's so simple to use.. (i even did when i started here) people think you should go through the hour long process of configuring all of your files, trying to create an evox boot disc over and over before it finally works, ftp each individual tool/folder over.... it's a pain...
if you have a mod chip with a good bios (evox m7 or x2 4981) then you can just download the 100 meg slayers 2.5 iso, burn it to cd-rw, and boot to it by just loading the cd-rw into the xbox. you will get an ip on the top of the screen, can ftp in and do whatever, and use slayers to install the dashboard and all the apps you want

of course you should still go in, read the ini's, upgrade whatever programs you want to update, and get a feel for how it all works. that way you will understand what to do if anything ever breaks on you
