Note that on some systems (Ubuntu for example) you will need to enable frame buffer
Do this by editing /etc/modules and add the following rules:
Then in: /boot/grub/menu.lst add:
to the end of a ‘kernel’ option here change ’769′ to the settings you wish to run at (see below) These are the value’s to choose from:
| 640x480 800x600 1024x768 1280x1024
----+-------------------------------------
256 | 0x301 0x303 0x305 0x307
32k | 0x310 0x313 0x316 0x319
64k | 0x311 0x314 0x317 0x31A
16M | 0x312 0x315 0x318 0x31B
Or in decimal:
| 640x480 | 800x600 | 1024x768 | 1280x1024
----+-----------------------------------------
256 | 769 771 773 775
32K | 784 787 790 793
64K | 785 788 791 794
16M | 786 789 792 795

Because some people asked me this question I will drop it here also instead of screaming out GOOOOOOGLEEEEEEE..
Creating a ISO image So you got yourself a nice little CD or DVD and want to make a ISO out of it. Well this is actually really simple just use ‘dd’ to create a iso out of it.
trouble@sun:$ dd if=/dev/hdc of=~/myimage.iso
Isn’t that easy?
Well to explain it a little bit:

| dd = The program that converts and copy's file's.
if=/dev/hdc = The Input source.
of=~/myimage.iso = The Output file. |
Note that this will not work always (copy protection etc..) but it works in most case’s if you want to create a image out of something..
In case its not working try looking at ‘mkisofs’..
Mount a ISO image
First create the directory where to mount the iso, then you make sure the loop module is mounted and then you can mount the image.
trouble@sun:$ sudo mkdir /media/iso
trouble@sun:$ sudo modprobe loop
trouble@sun:$ sudo mount file.iso /media/iso/ -t iso9660 -o loop
