Sorry, I must've missed your last post.

1. Xterm?  I really only use aterm, but I think the switch is the same... you can use like -sl 1000 for a 1000 line buffer.
2/3. This depends on what the software requires/modifies.  If the kernel itself needs to be changed, then you do need to do replace that.  If some extra modules need to be used or replaced, then you need to do that too - but you probably don't need to replace every one.
3. make bzImage is for the kernel packaging

Thanks for the xterm buffer switch, I'll try that.

Ref 2/3 - In overview, in order for the cpufreqd daemon to work and automatically manage Intel Speedstep settings to conserve battery life, it needs ACPI to be running, the various ACPI modules to be installed (fan, processor, etc) and a driver specific to the type of processor in your laptop.

In order to get the cpufreq driver, the 2.4.26 kernel needs to be patched - from the previous posts in this topics, you can maybe see that I have managed to patch the kernel source (I think).

I believe that if I replace the original DSL files with the ones created in the patch process, this whole thing will work. What I don't know is:

1. How to find out which new files are created by the patch/recompile.
2. Where to copy the new files to
3. How to create the new knoppix image file for DSL to boot from.

Doesn't DSL already come with acpi?...

If it adds more modules, you could just see which ones are missing.  If it modifies some.. well then I guess you could replace them - the paths probably are the same.  The kernel on the livecd is packaged differently.. if I remember, but you could also try any of the packages by modifying your bootloader.

You should see the topic of DSL/Knoppix image remastering.

You're right, DSL comes with ACPI and the ACPI modules - these all load on my laptop without problems and work. What DSL doesn't come with is the cpufreqd daemon and the cpufreq driver(s) that cpufreqd needs in order to work.

I read the DSL image remastering posts but I am missing the step that comes after patching the kernel source for the cpufreq driver relevant to my processor and before remastering - i.e. I apply the patch, make mrproper, make oldconfig, make dep, make modules, make modules_install but then what?

So you're saying you need to replace the kernel, add in the cpufreqd application, and add the drivers (which I assume are kernel modules)?

What happens if you try to load the modules now and run the cpufreqd application? (before packaging everything)
