Live Knoppix Is Very Nice Desktop Linux
Cheat Knoppix 4 to Improve Performance
Part 3. Advanced Knoppix Cheating
Mike Angelo -- 16 Janaury 2006 (C)
Next in Part 4, you will learn how to put together all the stuff you learned in Parts 1 through 3 to make a very portable Live-Knoppix setup. It's really very slick and it is very handy too.
In Parts 1 and 2 of this Knoppix tutorial, we laid out the basics of using Knoppix cheat codes. Then we applied those basics to:
Today's tutorial builds on what you learned in Part 1. Cheat Code Basics and the ALSA Cheat Code, and in Part 2. Performance Improvement Cheats to chain several cheats together at the same boot: prompt.
If you already have not done so, please read Part 1. Cheat Code Basics and the ALSA Cheat Code and Part 2. Performance Improvement Cheats Doing so will get you up to speed on the basics of using Knoppix cheat codes.
In Part 1 we used the knoppix alsa cheat to force Knoppix to use the ALSA drivers. Then in Part 2, we used the
cheats to make Knoppix run faster and to free a CD/DVD drive.
Today in Part 3 we will show you how to chain several cheats together at the same boot: prompt. As an example, we will chain the
cheats. That lets you both force Knoppix to use the ALSA drivers and also force Knoppix to grab its files from a USB key, rather than the live Knoppix CD.
You can use more than one Knoppix cheat at a time by chaining cheats. For example, let's say you want to use both the ALSA cheat and the performance cheat.
First tell Knoppix to use its default Linux kernel by typing
at the boot: prompt, just like you have been doing all along with the cheats in this tutorial series. Next, type a
following the kernel choice, knoppix, which you already typed in.
Now, your boot-parameters string should be:
This command string tells the Knoppix boot loader and startup process to use the default Knoppix Linux kernel and to force the system to use the ALSA drivers.
Next add the cheat code to force Knoppix to read its live CD image and files from the USB key, fromhd=/dev/sda1. So, type a
following the knoppix alsa string, which you already typed in.
Now your boot prompt cheat parameters should be:
knoppix alsa fromhd=/dev/sda1.
That directs Knoppix to use its default kernel and to use the ALSA sound drivers. Additionally, it also directs Knoppix to use your USB key to read its live CD image and files from the USB key rather then from the CD drive.
Then hit the enter key. That's simple enough, is it not?
You can chain as many Knoppix cheats as you like. However, only type the knoppix parameter once -- and only at the beginning of the cheats string.
For example, if you want to set your screen resolution to 1280x1024, simply add this text to your cheats string at the boot prompt:
Now the string of parameters you have typed at the boot prompt is:
Another caution is to be careful about which cheats you chain. For example, do not chain the tohd=/dev/sda1 and fromhd=/dev/sda1 cheats. It is doubtful that Knoppix can both read its files from the USB key and copy them to the USB key at the same time. So, use your head when chaining Knoppix cheats.
More Knoppix Cheat Codes
You can find more Knoppix cheats by hitting F3 when the Knoppix, boot-prompt splash-screen appears. Hitting F2 when the boot-prompt splash-screen appears provides a list of Linux kernels and other actions that you can try instead of the default Knoppix kernel parameter, knoppix.
There is a Cheatcodes And Hints For Knoppix V4.0 page on the Knoppix Web site that has an extensive list of Knoppix cheat codes. (Link in Resources section at the end of this article.)
Chapter 1 in Knoppix Hacks - 100 Industrial-Strength Tips & Tools (By Kyle Rankin, O'Reilly, 2004) has more Knoppix cheat codes too.
Look for Part 4, Computer on a Disc and a USB Key, coming soon. In Part 4, you will learn how to put together all the stuff you learned in Parts 1 through 3 to make a very portable Live Knoppix setup. It's really very slick.
