Introduction

Cheatcodes are codes that can be entered under "Boot Codes" (where the cursor is blinking) when booting a SimplyMEPIS LiveCD to change the booting behavior. They are used to pass options to MEPIS to set parameters for particular environments. You can test various cheatcodes using the Live CD's by typing them in at the grub bootloader. (just start typing when you see the various selections available and you'll see your "edits" at the bottom of the screen) They can be added permanently by Editing the GRUB menu after MEPIS is installed to your hard disk.

Table of Codes

NOTE: If setting a value, connect the code and value with an equals sign, e.g. vga=normal.
