From MEPIS Documentation Wiki
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.
NOTE FOR MEPIS 11: If setting a graphics value, always include confx after the cheatcode.
|3||boots the computer to runlevel 3, may not work in M8|
|acpi||off||turn ACPI completely off.|
|aufs||---||allows software to be installed during LiveCD session, see Aufs.|
|autox||---||in M8.5 and earlier versions of MEPIS, configures and writes x config file, useful if you change the video card or if you move or clone the HDD to another computer|
|confx||---||in M11, instructs system to create a new xorg.conf; the new xorg.conf file will be created using default settings from the /etc/X11/xorg.conf.in template file and autodetection; template defaults and autodetected settings may be overridden by using one or more of the following cheatcodes: drvr, res, hsync, vsync|
|drvr||---|| same as xdrvr
The "confx" cheatcode must be used with the drvr cheatcode in M11.
|fromiso||/path/to/iso||allows booting from an ISO, see Fromiso|
|hsync||range in KHz (e.g. "30-75")|| specify the horizontal sync range of your monitor (see your monitor manual)
The "confx" cheatcode must be used with the hsync cheatcode in M11.
|mem||MemoryRAMToUse||RAM size to be used|
|noacpi||---||disable acpi (Advanced Configuration and Power Interface)|
|noagp||---||disable AGP (Accellerated Graphics Port)|
|noapic||---||disable APIC (Advanced Programmable Interrupt Controller)|
|noddc||---||disable automatic use of Direct Digital Calibration|
|nodhcp||---||disable automatic use of Dynamic Host Configuration Protocol|
|nodma||---||disable the use of Direct Memory Access|
|nomodeset||---||instructs the kernel to not load video drivers, try this when you get black screen with nVidia using the nouveau drivers|
|nomsi||---||disable MSI, try this cheatcode if the harddisks are not recognized or if you have various PCI problems|
|nonet||---||boots without starting net|
|noscsi||---||disable SCSI devices|
|nofirewire||---||disable firewire (ieee 1394)|
|nocpufreq||---||disable CPU frequency scaling|
|quiet||---||don't list details to console|
|res||Number x Number|| set screen resolution (res=800x600, etc.)
The "confx" cheatcode must be used with the res cheatcode in M11.
|resume||YourSwapPartition||hibernation suspend file written to this partition|
|rootdelay||number of seconds||introduces a wait period that allows devices to settle down, try this if you have problems booting|
|single||---||boots to runlevel 1 (you can use "1" instead of "single")|
|toram||loads a live cd completely in ram, releasing the cd for use. Need 1GM minimum RAM.|
|vga||normal||used on older hardware to disable default resolution|
|vga||some value, auto||specifies framebuffer mode to display text mode and splashy. Read more here|
|vsync||range in Hz (e.g. "73-77")|| specify the vertical sync range of your monitor (see your monitor manual)
The "confx" cheatcode must be used with the vsync cheatcode in M11.
|xdrvr||vesa, somedrivername|| specify a video driver for your hardware. Use 'vesa' for generic, i.e. "xdrvr=vesa" Via/S3 chipsets may work with the fbdev driver if vesa fails.
The "confx" cheatcode must be used with the xdrvr cheatcode in M11.
|xres||---|| same as res
The "confx" cheatcode must be used with the xres cheatcode in M11.
|lean||---||disables some services for faster boot|
|nogui||---||disables Slim login manager|
|Xtralean||---||disables extra services for faster boot|
|Rox||---||enables Rox-desktop with icons (in antiX-M8.5)|
|noRox||---||disables Rox-desktop (in antiX-M11)|
|desktop=||fluxbox||Set live desktop. X is either fluxbox or wmii|
|dpi||96||Sets the dpi. Default in antiX is 96|
|homefs||/dev/sdc2||Set a persistent /home|
|rootfs||/dev/sdc1||Set a persistent /root|
|image_dir||boot/antiX||Useful for fromiso/frugal/liveusb. Place initrd.gz, vmlinuz and antiX compressed squashfs file in this folder|
|image_name||antiX||Useful for fromiso/frugal/liveusb. Name of the compressed squashfs file, default is antiX|
